[QUOTE="firefighter_324, post: 7795425, member: 642835"] I have a 2007 Dodge Ram Quad Cab Hemi. I have the following setup: - Pioneer P8400H stereo - Pioneer 8500D amp 1200w x1 at 2 ohms (This is maximum power) - Pioneer 9500 amp 400 x4 at 4 ohms. - 1 farad capacitor - 1 12" 4 ohm DVC sub in a custom box I have made under rear seat - optima red top battery - 0 ga power/ground wire Here is what I have done to try and fix my dimming problem: - tried without the capacitor = same results. - upgraded the amp power and grould wire to 0 guage wire (then 4 guage to the amps from dist. blocks) - tried a few ground locations and ground seems good under the middle seat belt bolt. (checked resistnace with voltmeter) - NEW alternator (factory 136AMP) - new battery (Optima) and then tried new standard battery (Duralast Gold) - Big 3 upgrade with 0 Ga wire (also upgraded additional grounds and power wires, cleaned connections) - Checked and re-checked wiring/grounds It sounds great but my headlights dim way to much .. There is no way I am pulling more amps than the alternator is putting out ..Others with more watts with facotry alternators don't have this issue.. Any ideas ?? [/QUOTE]
