FAQS WITH JP: WHY DO I KEEP BLOWING FUSES

There is nothing more annoying than a blown fuse! It is amazing how something so small can cause a world of trouble if not in proper condition. With extreme temperatures, high powered products and sophisticated wiring, it is important to make sure that everything in your system is hooked up properly and efficiently. It is very easy for things to go hay-wire because of faulty installations.
In this video, JP goes over why it is that fuses get blown or melt over time. Understanding the relaionships between amps and fuse blocks will save you a lot of trouble in the future!

My car has caught fire before because of a loose connection after about a year and a half. I've learned a lot since then and this video is very informative.

[@bl584]

Another issue can be cheap fuses themselves. I’ve seen them, even being the correct amperage, just heat up and melt.

As always good stuff bro!!! And thanks for the X12 y'all are sending me this week! 😁😁😁

Great vid and I would also recommend using ferrules with those high strand count OFC kits.

[@basscaddy1449]

For sure I used a trick I seen on how to fit 4/0 into 1/0 easy used a zip tie to keep the strands together saved me big time when adding a fuse block to my alternator wire with sky high 1/0 amp kit the wire is so big the nvx1/0 ferrules were to small

HEY, First of all, I’m a big fan I watch all your videos and I like and subscribe probably to the majority of them because I honestly do appreciate you and your team and everything you guys do . Moving on so I have a stinger oh gauge fuse block holder with a 250 amp fuse, and the same thing that kept the melting drastically. I’ll probably went through 10 of them. I do have a pretty big system. I do ask for a lot of power so I found out that for some reason the vehicle make and model that I have runs very hot and throws out a lot of heat when it’s raining during the summer that extra amount of heat being thrown from the engine along with you know asking for too much power already was causing my wire smell at least that’s what I believe. I actually look for a recall in my vehicle about the radiator or engine, throwing too much heat, and There wasn’t a recall, but there was many many many people who complained about the same thing for that make and model of the vehicle. I ask myself how do people in hotter time zones deal with this if this was the case.. moving on the solution to my problem, I got a 300 amp fuse, and I’m also going to attempt to 350 amp fuse see if that works and if not, I’m going to look for someone who could custom make a ceramic fuse block holder for me . I also ran OFC wire and have done the big three upgrade lol. Anyways. Any recommendations for a new sub and amp? I currently have two kickers 15 inch comp Q with a HIFONICS BRUTUS 3500 w amp and also morel speakers with a Morel 2500 w amp . Morel has great speakers

[@808Scenes]

Not a fuse question bcuz i need more power to even warm up my 300A fuse on my Salt 4k. So the question is when i do a 2nd batt with an isolator will the amp only draw power from 2nd batt even while the car is on as well? I know the isolator will cut off both batts while off.

[@ragextico]

I’ll always go with a bigger wire than the amp requires. Bigger wire = lower resistance = better power output from your amp👍🏼👏🏼

[@DTW-bx2vy]

The problem I have is I can not find any ANL fuse block that is 100% waterproof for using 4-AWG cable being I live in NY state & fall & winter season are wet & also very cold. I currently use a Sky High Car Audio - Set Screw ANL Fuse Block along with Sky High Car Audio - 4-AWG OFC power cable & SMD - 100-Amp Ceramic High Temperature ANL Fuses & I used silicone to seal it & try to keep moisture out of the fuse block but I still blow fuses. Do you sell a 100% waterproof ANL fuse block for using only 4-AWG power cable? I also wondered if I should just move my fuse block behind the firewall to eliminate the problem instead. But the run of 4-AWG power cable from the battery would be about 3 1/2 to 4 feet to the fuse block instead of a 10" length & I do not think it would be safe to do in all honesty. What do you suggest to correct this problem JP?

[@scrapenbass493]

What voltage should my single d3400 xs power battery be charging at xs power says no more than 14.4 for any amount of time then they say no more than 14.7 for more than 5 minutes but then they say your charging voltage @ 32°F should be 15.3 and @ 104°F 14.3.....maybe you could clear this up for us cause alot of people say charging at more than 14.4 will cause the battery to gas which will kill the battery over time but alot of alternators charge well above 14.4....please make sense of this👍✌

[@djkeys415s]

yea 14.4 is the charging rate for a 12volt batt in the morning your car will charg high untill it warms up and it should sit at 14.4 and above but not to close to 15 but if you get a realy good charger its gona charge your batt corectly

Yea it will , quality of head unit matters big time I know from buying the cheaper head units from Pioneer until I got a Pioneer 80PRS model and it made a huge difference on my system. I was so happy how it sounded after installing it , it sounded way louder and my subs sounded deeper and mid and high sound so loud and clean . I recommend spending the money for quality, you will not be disappointed and oh I have it on regular settings but if I want the best performance it has a switch on the bottom of receiver and it changes the rca. Inputs to get maximum performance and it activates the extra xovers

Good rule of thumb 2kw amp 200w fuse 1kw amp 100 anp fuse 3k 300a total fusing. Divide your wattage by 10 or 12 and start there if you blow fuses, go up 50 amps fused. That has worked well for me. Remember voltage x amperage = wattage.
