This FUSE BLOCK is awesome! Blue Sea Systems Review

In car audio builds we will always need wire distribution via fuse blocks for all the new devices we are adding, whether its DSP's, Active Line Output Converters, Equalizers, Lighting, Radios, etc. All of these devices require wiring, both a positive and negative lead and some also need a switched positive. In this video I review a fuse block I really like for custom installs, the Blue Sea Systems split system.

Happy Friday dudes! Can I get some love for 3 videos in one week? :)

[@fdfc78]

The hat trick is well appreciated!! Sidenote, I stumbled upon a video of you and Kyle Golden which was pretty awesome. Where did Kyle get off to? I heard he has left the car audio game. If thats true, its a big loss.

[@1-Six-dee]

Love ur vids man I think u would be soundman future self if he never discovered drugs n his youth

[@VanDamArtisan]

Love it! Never get tired of your videos. They are so informative and you cover so many topics that I didn't even know existed, let alone know how to do. Your finish work is spectacular and you are a true artist at what you do. Keep up the great work!

[@loloforge2841]

Good stuff Mark, keep learning with these videos!

[@robrodriguez4866]

Mark, please help me out for the love of God! I have been driving myself crazy looking for individual speaker harness adapters for my 09 altima s. ive found them on the metra site but only retailers can buy from them, from what I can tell. Is there any way u can help out? My factory speakers are driving me nuts and I would love a clean removable install

[@MrMeanderthal]

I work for company that builds multimillion dollar custom yachts... Blue Sea products are the ones we use most often.. they are extremely reliable and easy to work with.. I also buy their products for my personal use..

[@cliffbooth7075]

I used this fuse block for my diy wiring job on my caravan refurb.

[@jonnytacooutdoors]

What size are the positive and negative terminals ? 3/8? And the smaller ones 1/4”?

[@devinmartin7626]

Its also got a few more cool features, like the plastic is non flammable up to 1200 degrees for 45 min and even after that it doesnt really burn it "aggressively" melts without actually flaming. Their also disassembable to accommodate a sleek and hidden bridging of circuits and segregation of power supplies. They also have a minor ixp rating

[@chevybel6287]

Need your help. On the b part of the block for accessories, do I need to wire it to a relay ? Or can I just wire it to my ignition switch? Thank you so much for the great videos!

[@ZxSkyLineKidxZ]

Would this work with accessories like interior LED lights that come originally with a cigarette lighter adapter so I can get rid of the adapter piece? I simply want to have something to tap into if I want to run little low voltage accessories and make it look neat in the car instead of having a bunch of wires tapping into the fuse box lol I'm looking to tap into the ignition relay and run the power to supply to this block. Would you suggest this for my kind of use? Thanks in advance.

[@jonnnn4895]

Yes !! I would I’m thinking of buying it for this exact reason and having the switched fuse box for lights and other things and live fuse box for usb when car is off I can charge my phone with car off.

[@KH-yv1bo]

how do u hook a switched main power wire to it, im confused how this actually works….i bought one but lost at what to do

[@olliehopnoodle4628]

They make quality stuff. I have a fuse blocks and busses in my old Jeep. I take it wheeling often so that means a lot of abuse and vibration. No issues ever with their stuff.

[@i39440]

I use the 12 position + negative one in my bass boat. 1 single 4 AWG power and ground goes to the unit and provides constant power to my relay panel. They are definitely marine grade.

[@MautreXvids]

jacob p as far as i know blue sea makes marine stuff, that's why you have the ground distribution.

[@i39440]

They sell units with and without ground. I chose to have ground because I'm in a fiberglass boat. The only ground is the negative battery terminal.

[@MautreXvids]

Oh I did not know they had without ground distribution

[@paulleech6412]

You've got a bass boat? What size subwoofers? Must be nice to go far out on the water and just crank it up.

[@markemilyshepherd7981]

Designed for marine applications where you have to use full ring terminals as spade terminals are not allowed. Yacht standards do not allow spade terminals because of the motion at sea, spade terminals can theoretically slide out easier.

[@ThePewLife]

I ditched my Blue Sea for a Bussman RTMR. MUCH nicer quality, check them out

[@Thecarcissist12]

Im doing the same thing, not quite as easy an install, but much cleaner and built in relays

[@SnakebiteCortez]

Great video! Can you point me in the right direction to know when to use a switched vs constant positive fuse? thank you!

[@themagnet61]

Do you need 2 battery’s for the 5032 to work or can you run 2 taps off the positive side of battery to feed it?

[@garyluke8235]

Hello Mark, I am trying to decide how to power one subwoofer amp and a lc2i pro. How would you do this? I wanted to run one power wire from battery to the area where the amp is then use a distribution block to power both devices. I can’t find a block that will provide connection for a 80 amp fuse and a 1 amp fuse. Seems over kill to use 2 distribution blocks for only 2 devices. Any help you can offer? Thanks!

[@lakorai2]

Bkue Sea Systems Safetyhub 150 is where it's at. 4 midi plua 6 atc fuses in one unit + negative bug. If you need switched power then get a small relay and a 6 or 12 position atc block

[@EricDittmar]

Is there a relay you would recommend to connect to a 12v switched source to turn the whole block into a switched block?

[@thehifiwifiguy]

If the whole block needs to be switched, then you would just want a single circuit, fused distribution block.

[@juan2049]

So just so I understand correctly, you said not to use this to power the sub & amp? I have a 150W Sub/Amp I am looking to power with this

[@josephvolpe9296]

Just bought one, thanks. Do you still need to run an inline 10 amp fuse from radio to block?

[@snakeplisken4278]

Would the main -NEG goto your -NEG busbar and then two +MAIN screws to +BUSBAR then to battery?

[@supr_brd]

I love the channel! I really enjoy your work. I saw the question I had, posted on here but no answer. How do you actually deal with the switched side? I know that you need a relay but what about amperage? How do you wire the relay? Would love to see a video about this.

[@JesseOsby]

Very cool! That's a fantastic product. Dealing with sharing power for multiple devices like this has often been an annoyance for me

[@patricdocmanov2964]

I have a class d amp that requires a 30amp fuse. In theory, could this work for it since its within the tolerance of this device and im not going over the max amperage for the whole thing.

[@nextgenerationmotion2242]

Ive used this same brand for my audio in my bus conversion! It works amazing and I enjoy watching your reviews. Thanks for all your help

[@rossevans1774]

You are right the rattling will drive you crazy. And when you take the cover off it still rattles!

[@exbassguide]

I just installed that kind of fuse block and only one small thing to watch out for. When you remove the screws with lock washers from positive and ground wires you can strip or cross thread the screws. I stopped this from happening by rotating the screw CCW till you hear the end thread flip down into the hole a little farther, Then screw CW and you will not have a problem with cross threading!!! GREAT fuse block!!!!!! I would recommend highly!!!!! Roger The ExBassGuide

[@dangyll9686]

I've just discovered your channel and want to thank you for your videos!

[@tjb_altf4]

Was selling and using these at an old job 10 years ago, great to see they're still so popular. Looks like they made some really good improvements to the design too.

[@303nitzubishi4]

Just got turned on to this fuse block a couple weeks ago and thought it looked awesome. Thanks for giving an in depth demo of it. Would have been nice if stuff like this was readily available back when I was installing! I am about to upgrade the solar setup in my RV and I will be ordering one of these to re-do the convoluted mess that is my current distribution system

[@plugger410]

How do you make a six gauge switched wire? I get how I could just run a six gauge wire from the battery for a constant, but for my switched source, I’ve had to use the wire that’s already available there, running from the ignition switch. Obviously I wouldn’t just splice six gauge wire to the pre-existing 14-16 gauge wire. Thanks for your help, your videos are always super informative..

[@larrywebb8309]

I really like that fuse block with the ignition feature, I think it would be cool to ditch the clear plastic cover and make a custom cover using real glass or something simular

[@tombackes9557]

I purchased the ST Blade Split Bus Fuse Block 5032 for my 1984 Chevy S-10 to run auxiliary devices such as air control and gauges. My factory fuse panel is maxed out and I do not want to stack piggyback fuses on the factory fuse panel. Do you have a wiring diagram for running an ACC wire from my factory fuse panel to a continuous duty 150 Amp. solenoid relay to the bottom or switched side of the ST Blade Split Bus Fuse Block 5032? This way when I turn on my ignition the switched items will power up .

[@dustinsinn6688]

I love your videos man. I've learned a lot since I started watching. And the Material lists are fantastic. Too many video makers just show how to do it but never talk about what they use... And extra thanks for the also including budget minded materials and stuff on your lists instead of just top of the line, pro quality stuff. Not all of us system people can afford the best. Keep it up.

[@trollmafiaofficial]

For the switched side do I need to do relays for each accessory on each fuse or do you wire a single relay for the whole switched positive side? I can’t find a video on this! You should do one! I’ve seen you wore a relay into your set up in one of your videos but it wasn’t gone over in depth how you do your relays. (I get it’s not really audio related)

[@stevefernino]

I second this. It’s appeared in a few videos but never addressed in depth.

[@pantherfan7151]

Love the channel Mark! Thanks for all the knowledge you make available to us. I was looking for a nice fuse block a couple of months ago but didn’t come across this particular one. I ended up going to the local pull a part and snagged a really nice one from a wreaked police interceptor that was used just for all the extra bells and whistles like the lights, radios, siren ect. For $6 or $7. I just noted the year of the car and found the schematic online. Something to think about if someone has a lot of extras to wire in like I did.

[@TRX450RVlogger]

I farted once.

[@CharleneOrtizTraining]

Only once?

[@silentbravo]

Exactly the block I've been eyeing for a while. Blue Sea makes some great stuff

[@rolandos64]

I’ve never understood it. Isn’t this over kill? Battery/fuse/fuse block w fuse/ device w fuse....

[@CarAudioFabrication]

You don't understand the point of fuses. Watch this video kzbin.info/www/bejne/ZnmTYWiKmLB7gdE

[@spacepolice]

it doesn't matter what you did, Mark👍

[@markphilpot4981]

That Blue Sea block is pretty straight. Okay folks, so here will come out the haters and the lazy ones. Torquing the screws and or nuts based on the material they’re made of and for the thread, will yield consistent pressure, downward force on the connection in question. This may appear to be obsessive, but a car is a vibrating environment which g forces and other mechanical stresses are applied to the different mechanical and electrical systems in it. That being said, torquing of fasteners in a vehicle is not, in my opinion, obsessive. The consistency of the elements, such as connections, in this environment, warrant going the extra mile to ensure greater performance. What I have seen in race cars and in the military as well as in aerospace components, torquing of these fasteners yielded repeatable, consistent and reliable results time after time. Some things may sound weird, but that doesn’t mean that they are!

[@TheMainSilverSultan]

Just got a fuse holder for my first amp and maxi fuse is in there with good contact, but is easy to pull out. It just kinda slides out with a little force. But the plates are touching the fuse fully when in. Should I look for better fuse holder? Thanks a lot!

[@ivstova47]

I have one but I couldn't get the positive screws to work, so I put it on the main connector. Why? Didn't they work with the Fuze? Help

[@robertomiranda603]

Great video!! Looking for information regarding the braided wiring that you use, that is connected to the fused output. Thanks!

[@Wafreak253]

I’m a marine electrician and I use blue sea products almost daily. All their power distribution products are top notch. They have a safety hub 150 that will also accept higher amperage loads if needed. You should check those out. Also their acr’s are a great solution for charging multi battery setups and their surface mount breakers I use on all my car audio because they are waterproof. They also have remote battery switches that are amazing if you want to cut off high amperage devices and don’t wanna use solenoids. They even have a manual option Incase for some reason the electric switching doesn’t work.

[@pimp31012217]

Finally decided to get one for my auxiliary lighting. Definitely a must need for anyone running extra power off there battery. Great product and great review

[@zachpangos7159]

I wish you lived in utah, lol.... i would pick your brain for days about stuff.... I need help getting my system perfect-ish

[@zachcarlson3900]

Is there something like this that I could use for like 3 4channels, a dsp, and some lighting? 4 channels are about 900 watts rms. a piece.

[@billisnice]

Have you looked at the safety hub 150?

[@blockeduser5769]

A small peice of open cell foam 1" inch by 1" inch by 1" inch loosely placed in the middle before snapping the cover on will also keep the cover from rattling and can easily be replaced if it crushes and stops doing its job.

[@simonwoo5450]

Main lugs are spot welded, take it easy on torque - you can break that spot weld and the post will spin making it useless because you cannot tighten or unscrew from that post.

[@surferbird]

Do you use 12 gauge wire as your positive wire from the fuse box to the battery and what size fuse do you put in that positive wire to the battery if you don't mind me asking

[@Vanwives]

Hi, Where did you order those fuses from?

[@KW-N280]

Thanks for this! Great video!!🎉

[@jesussantillan4208]

Can you please show an example(process) on how you would connect a power window, adding a switch then how you would connect to the fuse box

[@eduardoromero149]

I hope you make a full video how to installed with the accessories switch for the car

[@georgespangler1517]

It's a fuse block for boats,,,I've installed many,,but I'm useing them in my classic cars now, work very well, and price friendly.

[@NeilKudro]

You skipped where to wire the negative terminals from any aux equipment.

[@CarAudioFabrication]

To the ground section of the fuse block... If thats not clear I don't think you should be doing this on your own... lol

[@ryanfritz8869]

If you can find one a Phoenix gold dd10 will achieve the same result and look way better, it's nice to have a "delay on" feature

[@cuen_recon6662]

Whats the difference between this and a relaybox i want to use it in a jeep for the lights and accesories

[@trumanbeal]

As per usual, excellent writeup- Thanks!

[@iproject1850]

Great video! But careful... you’re review is on the 5032, but your link is to the 5026 :-/ I almost bought the wrong item!

[@iproject1850]

Oh geez, now I’m confused. The title says split, but in the description, it lists 5026 as the part number

[@garrisonstanleigh6146]

I bought 4 of those fuse blocks . One for my car ,my Truck and 2 for my Tiny house Vardo ... Easy to use .. :-):-):-)

[@ct1762]

Really dumb question warning: I installed this fuse block on my boat and need to hook up my stereo head unit, but she already has a little 1A inline fuse. will the block still provide power without a blade fuse in the slot, or would i need yet another fuse to make it work? any idea what size fuse i'd need for a clarion cmd8? it says it draws 15A max, so im assuming 15A fuse.. or am I going up in flames 30 miles offshore?

[@Davidjohnson-mt8qd]

No, yes, and 15 amp fuse should be fine

[@AzzenGear]

Hey Mark, do you have any videos on how to actually wire LED strips in doors and consoles. I saw a vid you did a while back in the Jeep build where you integrated them into your amp cover piece but no one ever shows actually how the wires are ran to activate all the LED lights. I ask because I'm having a brain fart on how to get LEDs with the color changing mode into all 4 of my doors of my truck door pods.

[@CarAudioFabrication]

Its just like wiring any other 12 volt accessory.

[@2002erli]

Great Video- Thank you ! ! !

[@deezonmustardt6585]

Hey if caf made it , it would only be 100 bucks probably.

[@dssrbremer]

Yes nice I love working with those we install those on our police cars👍

[@JohnSmith-zw6tr]

I wish you would have elaborated a lot more on why and where you would need a “switched positive” for us beginners who are trying to learn. This distribution block also comes available as a “negative bus” block which is even more confusing.

[@jonnnn4895]

Switched as in car use when the key turns on it will power all the plugs and accessories on that fuse block for the switched one and having it live powered Fuse block will power it constantly with key off

[@kennethholifield1242]

Question for you ? I installed a lighting for my boat front and back lights , when I turn them on the Radio will stop playing? Any idea Thanks in advance great vid by the way!

[@joswald2001]

Literally just put one of these in my car for dsp fix and lighting. Great piece!

[@CarAudioFabrication]

Haha that's awesome, they make things pretty simple.

[@basharzaim]

What type of power wire you use to power Lc7i? Do you use fuse for it??

[@bens2890]

I have a question would this fuse box work for example say I'm setting up a patrol vehicle for security work and I am installing on overhead light bar 1 2way mobile radio a basic 40channel cb radio and a front end light bar plus 2 lighter ports I can't think of the name of them but if so I may get one but I'm just wondering first before I dive in and get the wrong stuff

[@CarAudioFabrication]

This would be a great block for multiple accessories.

[@crystalgarcia4724]

Can you run a 2 remote wire from amp to this is it safe or just use a relay thank you

[@canadoescalling1800]

Thanks for the video just want to confirm.. so 4-6awg power and ground wire from distribution block, let's say an Audison Sfd 41C, to the N- & A+ posts of the BlueSea panel, but for the switched line, would I be best to use my remote lead from head unit into BlueSea panel B+ post, or go into a relay? I want to have my two processors wired and fused thru a product like the BlueSea provides but need help with the switched line. Thanks!

[@jeremylecroix9512]

So Mark ,can i hookup my epicenter, and overdrive plus to this?and does my remote wire from head unit hook to either A or B on this?Thanks

[@justingardner4555]

I have one of these mounted to my test bench. It's complete overkill for the short wire runs that I'm using but it's nice to have a fuse for my small test amp and head unit. Eventually going to move it to the car when I ad cooling fans and LEDs. Every hot wire needs a fuse.

[@jeffreyscott4564]

Great explanation. I'm in the middle of an off road touring truck build and this video swayed me to buying the Blue Sea distribution block

[@jpsaudio08]

now this is awesome for wiring up multiple accessories. GREAT VID

[@blockeduser5769]

Thats a nice little fuse panel. But your hands in the intro made me dizzy...

[@psjr57]

What size gauge wires are recommended for the main +/- coming from the battery onto the main posts on the fuse block.

[@bryanpineda8614]

4:15 he says 4 or 6 gauge

[@marcodimeglio6667]

Whats better to use ring connectors or u connectors??

[@TheJoecb]

Nice looking fuse block. Great review and the rattle issue is simply solved. I'm adding a couple relays and a nitrous oxide system to my project car and I'm definitely going to check this company out.

[@MikeDraper-xe6ej]

how can a man wear a shirt with sleeves like that??????????????????

[@nayeemkhan5549]

How do i install for 24 v truck to 12 v stereo

[@milliethemini6369]

I have a very similar one just smaller, the one I have has a push and twist lock in the middle so keeps it nice and snug.

[@tomchristopher71]

Do you have a link to the wire loom material that you use?

[@rbo350]

I was looking for a fuse block for a solar installation for a van and your channel came up and I also liked the smd power distribution block

[@ericbrown9864]

I'm watching this for the same reason only running it from a house battery

[@chupamishuevos303]

awesome vid thank you again for the info

[@CarAudioFabrication]

+chupamishuevos303 thanks for watching!

[@endall39]

I've used similar, but not as nearly as flexible fuse panels in the past. That divided fuse sections allowing for both switched and constant connections, plus grounding is pretty darn cool. I found it's a little pricey for what it is, but I'll be using one of these the next time I do an install or an upgrade. Thanks for the heads-up on this product!

[@Phil-dg1yg]

Thanks! Awsome it’s a 100A max !

[@doc559]

🏆🏆🏆👍🙏 Thank you for sharing.

[@smooveb191]

Can i use this on a boat ? i have a couple of lights but i dont want to run everything directly to the battery.

[@giaro101]

I don't see why not as long as you wire it correctly.

[@icomba]

Good vid, do those connect right to battery or do i tap into something else for the power

[@mr.dpfaquariums4560]

You have me really confused I've been subscribed to your channel for a lot of years now. So I do respect your opinion on products. For instance in several years ago you turn me on to the KnuKoncept KNF-60 fused distribution block that has been in my current system for maybe 4 or 5 years now that's totally awesome !!!!! I will give credit where credit is due you did turn me on to this distribution block. You stated that this was not sponsored video but if you compare the two distribution blocks this block does not measure up to the KNF-60 in anyway what so ever. The point I'm trying to make is how can you like this distribution block now over the one previously ? I brought several distribution blocks ( KNF- 60 ) because of your video years ago and I must say they're not cheap! Can you understand my confusion? if so please enlighten me.

[@CarAudioFabrication]

+Mr. DPFJ Aquariums as I stated right at the beginning of the video the Blue Sea fuse block is NOT FOR AMPLIFIERS. The largest wire that should be connected to each circuit is 14 gauge. The KNF-60 is an amplifier distribution block designed for larger wire. And it's fine, I like that fuse block too.

[@tylersheehy3918]

Do yore service also install train horn?

[@wandamadden2726]

Great video. I've installed three of these. Two were 12 circuit and one a 6 circuit. All three powered LED lights, radio equipment and aux ports. The two 12 circuits were installed under the rear seat of two different Search and Rescue HMMWV and the 6 circuit I installed under the hood of my Jeep Wrangler. For the three years I've put it through a pretty harsh test in my Wrangler. It's been through dust, dirt, mud, water, snow and slush. It hasn't failed me what so ever. No rust, no corrosion and no broken parts. When people ask me what I did with my wiring for everything and I always mention the Blue Sea aux fuse block. Again great video. Blue Sea should hire you lol Sorry for posting on the wife's profile lol.

[@aaron5211]

What did you do about a relay?

[@mrevohk7423]

Mobile solutions use to have a nice fuse block but this one is better 👌🏼

[@frankolvera6487]

Does anyone know if this comes with mounting screws?

[@caddyguy5369]

I uses a Blue Sea Systems one when I added a second battery and rewired my DTS to my liking a few years ago. A+++

[@trd_tv1311]

what gauge wire did you run? i ran 10AWG because i have a truck and its runing the length of my truck to the back seat and then i was going to have it run leds and possibly relays to run large light bars? is 10 AWG overkill? mines not grabbing any power

[@kylesonsalla7620]

10 gauge to power the whole block is WAYYYY to small.

[@trd_tv1311]

SERIOUSLY? no way

@@kylesonsalla7620 what then? 6, 8 ga.?

[@evolve2survive324]

Hey Mark, do these fuse holders have an indicator light that lets you know when a fuse has bown ?

[@clatoris69]

No
