[@timgraysontv]

I have a 1984 Porsche 911 with the battery in the front and the engine in the back making it difficult to do the alternator. Is there a benefit in just doing the negative chassis upgrade only?

[@COMPASBASSCHICALI]

So 1 power wire from alternator to battery, 1 ground wire from alternator structure to battery, and 1 ground wire from chassis to battery?

[@thisguy1397]

www.GPcarAudio.com Sick. I'm gonna seriously consider doing this. Definitely Subscribed after seeing this video.

[@Exodia]

It’s nice to know that even at the most professional level you can set a bolt down for one second then literally two seconds later wonder where the hell you set that bolt at LOL love the content guys

[@Marco-fi6gv]

LMAO, true. I hate it when that happens. Bolts, nuts and tools, it can really drive u insane sometimes

[@crow-vz5lx]

Just like in real life lmao

[@crow-vz5lx]

Honestly, I just either fill my pockets, or I have a regular little box (Tupperware) I bought that I just keep on my tool box. Whenever I do any job. I grab the following. My cell phone My cordless ratchet My tool bag And the little box Pretty much everything I need

[@pq5005]

Hey thanks you guys. I bought the kit with you guys and it's way better than I thought it could be. It's amazing. And ya'll sent it here so fast. Hey really thanks.

[@scottduke4861]

You give a very detailed install and that’s how it should be done thumbs way up !!!! Glad I just subscribed should of done it a lot sooner

[@DENS973]

Cars and beer. Love it. Just ran my big 3 wire kit as well. Nice work. 👍

[@ryanmeyers2885]

Cars, beer & poosay. *Edit*

[@BeatsByThePound]

Did u run a fuse with your big three??

[@antbritto]

Thanks for this video, because I ran the big three upgrade and some other video suggested to run the alternator ground off of the frame where the engine block grounded. Let me tell you It arced in me. Then I remembered how these professional guys sounded and made it seem simple and it was. I ran 1/0 awg wire,straight we’lding cable. My car jams now, all the way around at 14.65 volts ! I love it

[@BigHemiNJ]

What's crazy is at 6:44 you finished the sentence "it's just gonna take us maybe ten more minutes to complete install here" and the video ends in exactly ten more minutes.

[@Losochill]

Just bought my big 3 kit from you guys!

[@stlboxchevy8841]

Good work bro..💯

[@me-pb6pk]

nice explanation of the upgrade..my only question is when connecting the grounds did they make a spark cuz my did..I wanted to make sure I'm making my connections correctly.

[@majorwilkesjr.5827]

5:11 I wish beer came with your Big 3 kit . Let's see if we can make that happen GP .

[@gpcaraudio]

Major Wilkes Jr. lol

[@oneal738]

Lol that would be an interesting kit

[@jayebonia8108]

why is so satisfying to watch is it only me

[@JAMIE_ATKINS]

AWESOME! What size bolt and thread pitch for the ground to frame?

[@LownSlow80]

I have my negative from the battery to the frame and from there to the engine block will this work also.

[@oneal738]

Great work

[@tremaynemorris7685]

How did y’all install the SAE 6 bolt battery terminal from the factory positive and negative wiring?? I have a 2004 Grand Marquis and I would like to add the new terminal

[@shamirsims1]

Well needed information thanks

[@MegaRcdrifter]

Can I hook up a 2000w or a 3000w amp to Memphis PR subs? Some people have hooked up a 1000w amp to those subs but I'm wondering if it's possible to hook up a bigger watt amp.

[@eacalways]

Got some questions.1)are these only for older cars?2)I have 2017 Subaru Legacy with stock audio system,but have some led bars installed,would it be ok to install these Big 3 upgrade even though I don’t plan on installing aftermarket sound systems?and also power from battery to alternator doesn’t it need to be fused?and how would I know what amp of fuse I need,?i plan on getting your 1/0 gauge kit,thanks

[@hippo-potamus]

I know that a short to ground on the alt to battery power wire will be virtually zero but what if the alternator rectifier goes bad and shorts out? Doesn't the stock amp to battery have a fuseable wire at the junction box?

[@bearxbunny1835]

Damn I wish my alternator was so easily accessible!!! The big 3 is a breeze for you

[@kylekaden7696]

Amen I have the battery in the trunk terrible

[@miguevalen8683]

Thanks guys best and easiest big 3 install video I've seen now I'll be able to do my big 3 install 👍👍

[@psementalist]

I love me some Big 3 GP style I'm actually thinking about replacing mine on my 96 Ford Probe hatchback Se named Praisenator .

[@gpcaraudio]

nice!

Intro was kick ass!!! I was jamming. Who is that?

[@youngdaggerdih]

[@yusufjorgenz5951]

I went negative on battery to chassis...5 inch wire. You went negative to engine block. What should I do? Make a 4th going from negative to block or replace my negative to chassis? One more question.. Do pure copper ring terminals make any difference or do the gold plated or aluminum work just the same? Is it worth the hassle changing them out?

[@270trevon]

My car has a battery sensor on the negative battery post cable and I was advised to not connect any wires to the negative on the battery. Would I just ground the alternator to the chassis and leave it at that or could I do something else.

[@jsteezy80]

Does it not need to be fused from the alternator to the battery? I just bought your kit and getting ready to install it but some videos show them fusing it. Thank you in advance

[@josheybae1157]

Sir I want to ask..my alternator is 100amps output..I installed power wire directly into positive of alternator to the positive of the battery with 150 amps fuse..Iam also having sound system 2 amplifiers also with fuse but lower amps..my question is shall I need to replace the fuse of may power amplifier into 150amps??coz its all connected to the battery??to avoid toasting of fuse??

[@shamirsims1]

What size screw for the bottom chassis mount and what did you drill the holes with

[@restore64]

Any reason why you used non-tinned copper ring terminals versus tinned ones? Thanks.

[@JamieCarAudioChannel]

Are those top post terminals on that north star battery if so do you have a link of where I can buy them

[@mawethumgeneral9763]

Is there a need 2 have second battrey in your car for the sound?

[@ALEX-xd7ko]

Funny as hell . I remember when i suggested to Justin that they should sponsor car audio and he said " there's no market there that we really want to be part of " now they sponsor bass heads lol.

[@grady.stu.8300]

I am team GP 100 percent! Love your guys products. Best wire in the business!!!

[@drvictoria07]

Awesome 👌. Are you all ofhc wire tinned? I see it's for marine use as well.

[@harleyhull862]

Would it matter witch alternator bolt you use for negative battery to the bolt?

[@theimmaculatecrown]

I followed this guide to install my Big 3 Upgrade today. Thank you! Only thing is the beauty cover doesn't fit with the wires that high. I had to push them down a bit.

[@sgt.7133]

Yo! Appreciate the info...👮🏽‍♂️👍🏽 Question... Do I need to disconnect the NEGATIVE first, before hooking up the POSITIVE from the alternator to the positive battery post? And then, the NEGATIVE from alternator to negative battery post? I don't wanna fry any components...🔥

[@larryoliver4392]

What did u spray on the frame ground for protection

[@ganzonomy]

Just ordered my 1/0 big 3! Do I need to unhook the battery terminals from the battery before doing this? Or remove battery altogether? Thanks

[@nuffsaid5205]

Because youre not breaking the circuit between your battery and vehicle you shouldnt need too. But if you are working alone then you can disconnect the ground in case youre not comfortable.

[@VareaIII]

I have a crown Vic and done this but the top alternator bolt will not fit the 0 gauge and stock connection. Do I need that stock wire bolted up?

[@larryreed6121]

Does the chasis ground wire go from the body of the vehicle to the battery?

[@waterborne4072]

Are you leaving the original wiring connected in addition to adding the new wires?

[@jweyman88]

For your original negative wire that connects to post of battery.....what did you do to it? Did you take out? Cut and put new lug on it? Wondering bc I have the 6 spot flat terminals as well and I’m not sure what to do with that specific negative

[@nathanwhite8931]

I have the same thing. I just order my big 3 I’m going to cut the wire and put a terminal. Never hurts to have extra power and ground lol

[@sunnyvale4088]

Can i just run the negative to frame on the side where the battery is, on the iner fender there's a small wire grounding the battery

[@nocturnalish]

Did you keep the original wiring from the starter to the alternator? I'm doing this an a Chevrolet impala ltz. I need to know if those have to be removed.

[@sinisterfox2330]

No you can go on top of stock wires

[@bigboigarage6877]

Hey I have the same car and year. Is there anyway to get a list of mods you guys did or upgrades to what system you're running

[@gpcaraudio]

We just started building the car, stay tuned, we are about to install a 390 amp alternator today

[@mrmeiii]

Ok I do my big 3 a lil different,since the motor mounts are insulating the motor from frame with rubber ,and the body mounts are rubber and you usually ground ur system to the body ,why don't u have a body to battery ground???? That's how I do mine alt to batt,block to batt,body to batt am I wrong???

[@michaelcampbell8948]

I need to no what alternator i need for my 89 grand marquis. because the orginal has no alternator power screw. they have plug ends. Need help asap.

[@thomasforen988]

? Im running 2alpine type x on 3 k rms is that 2 much for them also im running 4 gauge power and grounds and im getting clipping at low gain so im assuming i need the big 3 upgrade and thinker wire from battery to amp please let me know what u think

[@jdigitalseven7]

I think for pre 2010ish this should be a good thing..but not so much for modern cars and all the electronics...cars electronics today are strict with everything it seems

[@megaman010391]

That's what I'm saying I have a 2018 Kia Sportage and the wires look decent in it comez with a stock 150 amp alternator. I'm running a 1400 RMS amp And a 400 RMS voice amp. But in reality I never do those numbers because I'm only running 1 12 inch sub. So I don't think it would be necessary if I installed the big 3.

[@peppilameu3144]

The question I have is do you guys not install a fuse block(250->300A; depending on usage)

[@bigmike4720]

Can you do a video of the big three on a Tahoe or suburban

[@2wheeltommy595]

When I run a second battery in the back of the vehicle can I come directly off of the alternator or do I have to feed it off the 12 volt battery from the front

[@MrBiscuitsAndmustard]

I went from positive terminal on front battery to positive on back battery

[@MichaelJohnson-gi9mn]

If it's a Ford why did you cut out the fuse box relays to the battery

[@truckman7123]

Hi, is it safe to connect charging wire from battery to alternator without passing thru the fuse?

[@BRENDAJASON1]

I’ve seen some that run the block wire to the frame. Is it better to run the body and block grounds all to the neg post battery

[@chiphill4856]

The big positive wire from alt to battery should be run under the a/c line to match up w the negative. Cut all zip ties w flushcutters.

[@Mr.Weatherspoon]

Would Like to know what you paint over the bolt on the frame to keep it from oxidizing and sealing it?

[@HIGHROLLAZAUTOCLUB]

What about for a Chrysler 300 when the battery is in the trunk. What’s the best way to run the big 3.

[@patjones8204]

I have that same big three kit but the terminal doesn't fit on the positive alt because that little rubber piece wat can I do to make it fit better

[@chadthemannable]

Going over the cvpi electrical diagram , a fusable link is required from the 200amp alt to the battery. Do you not need that or a circuit breaker of 250a

[@djayewes58]

I have a 97 towncar is this the same? I cant find stock engine ground..is the short wire from ur batt neg to side of car a good ground

[@redbeacon4871]

Yes,make sure to scrape off the paint if there's any ,you want the ground wire to touch bare metal

[@247huerohuerta]

Have you ever had any issues by not fusing the alternator to the battery..

[@realn7374]

Wait should you do this with stock alt or is this just for high powered systems or people with more then one alternator

[@relaxationnation1189]

Real N helps either way

[@moe8599]

So I see some people have a fuse between the alternator to the positive battery terminal and some dont is it really necessary ?

[@mr.bailbond151]

I have a 2004 Grand Marquise and would like to know what do you do with the factor alternator power wire? Also can you give me the link to your Big 3 upgrade kit?

[@gpcaraudio]

Hey I think you called me earlier and we are getting you taken care of today. If not call the number on our website and we can explain everything crystal clear 👍👍

[@ryanmccafferty6322]

What kind of coating did you use for the second ground? Going to run mine the same way.

[@yusufjorgenz5951]

I went from negative to chassis about 5 inches of wire. He went negative to engine block. What should I do? Leave it or add a 4th ground?

[@Malek-b]

How would this work on a 2017 Ford Fusion Hybrid Se? I plan on having a system 1200-1500 watts and beneath my hood is different. I have a stock battery in the left side of my trunk as well.

[@livingonadollar2882]

I would look into getting a higher output alternator first Ether one that is compadable with your fusion Or a Aftermarket one made for your fusion. example My Chevy Blazer Alt stock is a CS-130 rated 85Amp. Tahoe and other GM trucks Use a AD-244 rated 105 to 190 Amp which use the same bolt up and pin connector, (1 inch bigger belt) and sell for only $40 more then the stock CS-130...After market CS-130 - 145Amp sells for $110 more Next would be your wiring system Then a battery upgrade

[@Malek-b]

James Mb there is no alternator on my car. I’m thinking about just upgrading the rear battery cause I just got the skar Rp1200 with an EVL12

[@Malek-b]

James Mb I honestly don’t know which battery to get

What's the spec on air intake?

[@rileypowell5795]

I grounded my engine block and battery to the frame, then ran power from alt to batt. 3000 watts, but 2 runs of 1/0 each. Is this alright?

[@uptobatentertainment]

Riley Powell yes that is a normal big three upgrade if you upgrade your Alt then you may want to run another ground from the alt ground to negative battery. Search Big 4 Upgrade lol Have a good one

[@ramonstrong8107]

Do you need to put in a better battery and alternator to do the big 3?? Or can you do the big 3 on factory battery and alternator!?

[@gpcaraudio]

Ramon Strong you can Definetly install the big 3 without upgrading the stock battery or alternator, it makes a big difference. Then from there upgrading the battery and alternator just increases the results even more

[@ramonstrong8107]

Thank You.... For letting me know!!

[@gpcaraudio]

Ramon Strong no problem

[@kiabass8798]

gp ftw

[@c.n.h4841]

Can you make sets that have longer ground leads no other company sells the with longer then 3 feet for chassis two ground wires lifted trucks always need a little bit longer on the grounds 48 to 64 in

[@gpcaraudio]

All of our universal kits are 48", but just call us direct on the number on the website and we can make anything you need down to the inch.

[@thomass9099]

I got a question do I gotta unplug the battery or anything before I install the big 3 kit so I won’t get shocked or spark anything ?

[@slow_rednline4874]

Duh🤦🏾‍♂️.. I would disconnect the battery positive so that you don't arc yourself or car to death

[@skywalkerclone1978]

Do you need a fuse for the alternator positive power wire?

[@matthewhenry9243]

do you keep the stock wire from the alternator to the battery?

[@CliffdropChad]

Yes, always retain the stock wiring if possible. Add, never subtract.

[@britneybrusnahan5217]

What are the other wires that you didnt show like the real short chasis ground next to batt neg

[@gpcaraudio]

Britney Brusnahan That's where the stock 4ga ground was we just swapped it out with 2/0. The wires on the positive were just stock wires, we crimped lugs on them so they could be bolted to the new terminals

[@MrWtfjusthappen1]

What did you spray on the ground wire under the vehicle so it doesnt rust?

[@gpcaraudio]

MrWtfjusthappen1 I think that was just a rustolium black spray paint. Or plastidip

[@richboss1705]

What will i need to do if i im running over 21000 rms. big 3 wisevplz help gp audio.

[@idrinkpowersteeringfluid]

If you're running 21k you're going to need multiple alts and batteries.

[@HamsteakStudios]

If you're running over 21,000w RMS and you don't know what you need in order to feed that system, you are already wrong on so many levels dude. I'd suggest reading up a little bit for your own well being rather than relying on other people to hook your stuff up.

[@jeffreyallen3796]

Your website is the closest to coming up with an alternator for 91 Nissan Hardbody. A/C compressor mounting bracket is open.

[@justotomuchforone4643]

Wats the size battery you use for this build an can i use two for my set up 1600 watts amp 2805rms

[@anishpatel5715]

Get a High output alternator.

[@dewaynecurle7396]

If you add a second battery; would run a positive cable straight to the second battery or use a isolator?

[@gpcaraudio]

skip the isolator, you want to be able to tap into the underhood battery power also. positive to positive from battery to battery, fused on each end to isolate the run

[@dewaynecurle7396]

Thanks guys.

[@JOSEPEREZ-ul1zn]

Hey you think that if I have the big 3 pluse an extra baterry will work with a 8000 amplifier?

[@gpcaraudio]

On 8000 watts you'll need a Northstar smsagm480 battery and need to look into getting a high output alternator

[@anishpatel5715]

For 15K I have 10 batteries and 3 HO alternators. There is an electrical calculator app you can get on your phone to give you an idea.

[@sinisterfox2330]

The ground on the alternator should come out the back of it it goes from ac to DC and alternators ground out the back not the front and the reason why is that the ground now has to go through the whole alternator to get its ground

[@blargblarghonk]

It's funny. I did the big 3 with 2 gauge cable with soldered and crimped ends and frame, block, body grounds. Also used 2 gauge to alt and bus bar(old shit with weird electrical). I saw no change at all. Same voltage off alt and a negligible resistance to battery drop. For anything over 1000 rms system's I think the entire secondary electrical system should be isolated from the primary electrical system. Separate alt, battery/ies and stand alone ground and cable runs for best efficiency so the stock system is unaffected by voltage drops during heavy loading of the electrical system. Would lead to a better overall performing system as well as less taxing on the stock electrical system. Granted reducing resistance from alt to battery to ground is still a good idea for more efficient power distribution.

[@j1rdf335]

Get ur self an high output then do the secondary connection and yes it will work completely isolated lol i have 99 tahoe with an ambulance alt 2 extra bat my tahoe has and extra battery plate in front im running 2 double 0 welding wires from front to back i have 4 txx bd4 and a couple of amps 1 for each pair of bd4 i have ex amp for mids and ex for tweeters

[@mawethumgeneral9763]

Hi guyz is posible 2 do do thuh big 3 in any vehicle?

[@drewcarr8191]

So you don't fuse it from between alternator positive and battery positive? I saw a few videos where they run from alternator positive fuse it then run another wire from fuse holder to battery positive

[@poopandfartjokes]

Yes you need a fuse on the alternator power wire. Not sure why he didn’t do this. He mentioned that you COULD put one as if it doesn’t matter. It does matter and you do need one.

[@jrobb7539]

What did you do with the original 12 volt cable that was on the alternator before the upgrade ❓

[@liljay8076]

You just add the zero gauge you don't remove any stock wire

[@liljay8076]

So just add it with the alternate wire

[@tinman9341]

So the upgraded cables get added on top of the current ones or are they to replace the OEM???

[@jamal2490able]

Does anybody know why they needed to separate the positive and negative wires?

[@shaunoguinn1015]

Think I'll need a high output alternator for a 08 sierra 4.8 with 4000w rms?

[@mafosa8519]

why was there two wires on that alternator? no fuseable link?? just asking? larry

[@code3responsevideos872]

mafosa one was stock and one was big 3

[@grimreaper7862]

One was a ground

[@Quanie156]

What drill bit and thread did u use to drill the hole in the chassis at the bottom

[@gpcaraudio]

Shaquan Hardy 5/16th drill bit and 3/8ths tap, we use flange head 3/8ths bolts to secure the grounds

[@MrCrf450rider]

Shaquan Hardy you can but frame tapping bolts.You just have to drill a pilot hole corresponding to the bolt.they have an appearance with a cone type of thread,and they work great,if you don't have a tap set.or grind frame,and weld a bolt to it,or this.

[@kyle.vlogs2023]

Will this fix me ecletical problems with my 05 gmc jimmy?

[@gpcaraudio]

[@kingofkards1110]

Questuion are u adding wires or are u replacing the original ones with bigger ones?

Adding wire, leave all stock wiring in place.
