i'm pushing about 1100-1200 watts rms @ .9 ohm yes kiddies .9 ohms and at first the bass would hit so hard that the headlights on my car would dim very baddly and i tested the voltage drain by then turning on my dome light which would completly shut off when the bass hit. yea its ghetto but it works and gives you a good idea of how much current your pulling . i'm pulling about 150 amps total

so i looked around and looked at 1 farad caps which don't really do anything and will not really solve any problems
and all the way to 5 farad caps.

then i found the answer BATCAP check out xstatic batcap its half battery half cap and works great.

now when the bass hit my headlight only dim a very little bit and the dome light only dims a little too.

if you running a big billy bad a$$ system you'll want to do a couple of things .

- upgrade the factory ground . run a 4 gauge wire or what ever matches your amp's power wire from the - terminal post on the factory battery directly to the ground of the car less than two feet of wire . theres a nice spot under the air filter on the transmission mounting bolt. be sure to scrap the paint off with a wire brush in a one inch square of bare metal. if you have a chassie ground aka the - ground wire off the amp grounded directly to the chassie ground in the trunk. if you screwed the - ground wire off the amp to a metal surface in the trunk this means you !!!

- upgrade the + wire that leads from the alternator to the + terminal of the factory battery with 4 gaufge wire or at least the same size wire you are using to power your amp this will help recharge the stock battery a lot better

- running the - wire off the ground of the amp directly to the - terminal post of the factory battery if possible this helps out a lot compaired to just grounding the - wire off the amps ground wire to a chassie ground

yea boy also dynamat doesn't really help . i dynamated my whole trunk , the lid, under the spare tire, the rear deck, ect, and the trunk still beats like crazy. it was a waste of money if you ask me



I'ma go ahead and call some BS on this one. You NEVER want to run a ground that long. Going from the Amp's - to the Battery's - would mean a long run. Long ground wires equal what class? Bad. I'd get into it, but I'm tired....
