99blazer Posted January 23, 2015 Report Posted January 23, 2015 Just recently I have noticed my interior lights are dimming when playing my music at high volumes. My setup currently consist of 270amp singer alt d3400 under the hood d975 in the back I have 2 runs of 0gauge running to the back for the positive I did the big 3. im running an aq2200d at .5ohm with dual power and ground inputs and a aq 120.4. I am stumped at this point and could use some help. I soldered all the lugs with 60/40 rosin-core. I am wondering if that could be it. 08 Ford F150
SLYentist Posted January 24, 2015 Report Posted January 24, 2015 the solders are a possible culprit. check your grounds. did you run a ground to the case of the alternator? Cables and wires almost never fail; the terminations do.
99blazer Posted January 24, 2015 Author Report Posted January 24, 2015 Not to the alt but its grounded to the body the block and to the frame 08 Ford F150

d-nice88 Posted January 24, 2015 Report Posted January 24, 2015 how do you have your gains set ? are u using the bass boost ?? if the gains are set wrong that could cause head light dimming and using the bass boost. i know cuz ive had that problem. still got some dimming but i think i just need an extra batt
99blazer Posted January 24, 2015 Author Report Posted January 24, 2015 I set the gains with a dd1 and I don't use bass boost 08 Ford F150
SLYentist Posted January 24, 2015 Report Posted January 24, 2015 12.6 is a little low for AGMs, but it's not too bad. is the alt in the stock location, or is it on a custom bracket? Cables and wires almost never fail; the terminations do.
