hey guys, so i think i may be having a problem with my HO alternator? so i have an 00' chevy silverado ext cab 5.3L with a dc power 190 amp oem alternator. 4 RF p1 10 in subs under the back seat, 2 amps for the subs and a 3rd amp for the front door speakers. sony xplode HU and front door speakers (I know crappy). but anyway. i have done the big 3 with 0 gauge, 4 gauge to my amps. 0 gauge body to frame ground. and my amps are grounded directly to the frame. now my voltage gauge flickers at idle, even more so when my turn signal is on. my headlights dim slightly and voltage drop when i hit the brakes at night, serious voltage drop when rolling up both windows. now mind you this never has happened until i installed the system and it even does it with the amps off.. is my alternator faulty? its only a few months old and the battery is fairly new too.
