i have an amp that im using 4 gauge to give it power and 2 gauge to ground it. it blows fuses at loud volumes, could the difference in gauge wiring be a problem?
Ill try to turn the gain down a bit.sames size wire, turn the gain down, and make sure ground is solid, should fix ur problem
Thanks for reassuring me. Fuse is my next question actually. I'm using 100 amp agu. Should I switch to anl? Someone told me 100 for agu was too much and they cant handle that much power.It's fine to have a larger ground. What size fuses are you using?
Thanks 01. I only had spare 2 gauge so threw it in there.Yeah, 2nd on if you are gonna use larger wire on one, it should always be the ground. Never the other way around.
Are you running the gear in your sig off that four gauge? If you are, I have a feeling you are in need of an upgrade of wire. Also, is the wire copper or cca? That makes a difference in this.Ill try to turn the gain down a bit.

One more piece of info- when fuses blow and I change them immediately I notice the power wire is a bit warm. Any correlation?
Yes I am. I have a run of 0 gauge to the back and from there its distributed with the 4 gauge mentioned above.Are you running the gear in your sig off that four gauge?

If kicker its using cca, its news to me. your wire should be ok. I'm assuming its only the sub amp that is grounded with two gauge. Nope, if you're using a 100 amp fuse on quality four gauge, and running over 100 amps through it, that will cause problems. Decent, quality, four gauge can safely transfer well over150 amps in shorter lengths. Around 150 in longer lengths.Yes I am.

The wire is kicker hyperflex. But the one I'm using on the amp that is blowing is the newer kicker wire so I think its the cheaper cca stuff
Yep.Yeah the problem here is you are using too small of a fuse. Your amps are drawing more than the 100A that fuse is rated for. Switch to ANL, fuse for the capacity of wire. 250A for 1/0ga, and after the distro block run 150A fuses to each amp.
I have a 300 amp fuse on the 0 gauge and then a 100 amp on the 4 gauge after the distro. JL says to put at 100 amp. On it? Idk if I shouldnpush it and do more. Especially considering the price I paid for it off the forum (no warranty lol)Yeah the problem here is you are using too small of a fuse.

Haven't checked this specific wire on this amp to be honest. But kicker has always been good for wiring. And yes only sub amp has 2 gauge ground. Other amp is fine.If kicker its using cca, its news to me. your wire should be ok. I'm assuming its only the sub amp that is grounded with two gauge.

Yep.
Oh, you didn't mention that before. Still, for 4ga 150A is where you should be. But make sure that your gains are set right, that you're not clipping and drawing large amounts of power. Also make sure there are no shorts or anything like that.I have a 300 amp fuse on the 0 gauge and then a 100 amp on the 4 gauge after the distro. JL says to put at 100 amp. On it?

So switching to anl is my best option then?
Lol, yeah he rents it. He's a good dude. Not really making crap of it, just sharing with the caraudio peeps. The ad is in the misc. car audio classifieds.Ill have to double check gains I guess. The amps are mounted where I cant even see the gains so I haven't touched them yet since initial set up that I had ball parked to get things running before tunning.
Lol he rents it?!
Ill have to check gains then. Everything else seems fine. The amp turns on/off perfectly and plays at low/moderate volumes perfectly too. My power run to it is only like 3 to 4 feet tops
