hey guys, this is my first post on a forum and id appreciate any helpful suggestions anyone has. My question is about headlight dimming, my system though consists of HU-kenwood ddx 318, boston acoustics 5x7 door speakers powered by a JL XD 400/4, sub is JL 12w7 (anniversary edition) powered by JL HD 1200/1 with gain lil below half, Big 3 upgrade, with extra ground on main battery, 0 gauge wire for big 3 and power runs for amps, 4 gauge for door speaker amp, xmax charge tank CT600 i believe it is in trunk for sub amp , fused with isolator. my question is, when I put the system bass knob on dash all way up, and volume up to 30 on heavy bass hits the lights slightly dim if i keep bass knob half way and volume around 22 no dimming occurs, alternator is 150 amp, its a 2009 escape, 3.0 v6...What can i do to stop the dimming if i crank it ..volts dont drop ever under 12 to 12.5 mostly stay at 14 to 14.5 on most songs, I want to do all i can to stablaize volts from moving and lights dimming if i crank on it, but i dont wanna change out alternator cause might sell car within the year what options or what would be best to do,I dont know if I get rid of trunk battery and get a lil bigger one if that would help or if I get a capicator, ( but Iv never believed in capicators so im not sure) any advice would greatly be appreciated...each audio shop by me iv taken it to I get told something different so I dont know.
