Alright somehow, the guy before me messed some serious stuff up, he has a battery terminal with 5 diff things going thru it, fuse box, amp wiring, direct power to deck wiring, and what i think is for the starter and something else.
So basically he had 1 alpine type r in there, which anyone knows it a decent his, and powers higher then 2 kicker comps, when he had his system in, guage/headlights wouldnt dim, but with mine they do, also if i turn it up to the usuall 18-19 volume my deck just turns off then turns back on, like its draining the battery, which also makes the lights flicker when the bass hits, my question is, is it my deck hooked up wrong, ****ty amp wiring, or is the source coming from the battery terminal..

Thanks
