its in a 96 chevy lumina, and i guess the lights arent dimming to bad but they are dimming. i adjusted gain and it doesnt dim as much, and double checked my grounds which are perfect. ill try to re run from batt-fuse box when i get a chance see if it works. thanks for the help people, any other ideas? if i get the redtops should i isolate them? and i can get scosche batteries with a dealer discount would they be worth it to try? thanks again.

oh sorry, yeah 1/O from batt. to dist. block, 4 gauge from dist. block to all 3 amps. the reason im askig this is because the amps have over 200A worth of fuses in them, 75 per alpine, and the jl says it pulls ~60A in the manual. and then fact. equipment and all the rest. just wondering if there is a more efficient way besides having to make a bracket for a 250A+ alt. because i have a small engine, (3.1L) and a cramped engine bay (96 chevy lumina)

grounds are down to bare metal, i will check gains tomorrow. thanks

single 1/O ground from dist. block to chassis. used a wire brush to scrape it, all metal. bolted down. single battery, starter battery.

Whats up. So i have a little system going on. Just got sub and sub amps installed the other day. For starters I upgraded my underhood wires, the big 3, all to 1/O wire. Upgraded alternator to 200A alt. from Natahn @ excessive amperage. Have 3 amps.. 2 Alpine MRD-M850's and a JL Audio 300/4. Clarion drz-9255 h/u. Sub = Re Audio 06 XXX, one Alpine/coil. Sub is dual 2 ohm version. Front stage = JL Audio zr5.25csi, i know overpriced but i bought them well over a year and a half or 2 years ago they sound great. 1/O wire running from batt. to trunk where the dist. blocks are. When i'm driving the lights still dim pretty badly. I was wondering if anyone had any further suggestions on what I should do? Thanks for the help, and im new to the forum also.
