Lights dim when bass hits, weird.
I have a 2001 VW Jetta with a custom system, I recently look out my carputer, but recently my lights have been dimming bad when the bass hits. Here is some background info and things i've done:
Setup:
ALpine 9852
4x Infinity 6012i's
12" pioneer sub 4ga wiring
800w pioneer amp for sub
1.5F cap in the line
The problem:
My lights dim when the bass hits for my speakers, not my sub. Its weird as hell. I can turn my sub down to zero, and keep my speakers at 0 or +2 or -2, and my lights will dim. Even if the sub's RCA's are disconnected, the bass hits for the speakers cause the lights to dimm. ALL the lights dim, rear, headlights, dash, internal lights, etc.
Heres what I've done:
Rewired the whole car twice.
Upgraded alternator from 90A to 120A
New starter
Redid sub wire with brand new 4GA
grounded everything to bare metal (HU, sub, all electronics in the car)
DID THE BIG THREE (upgraded ground wires in engine to 0GA)
Fused yellow and red wires in the HU harness @ 10A
Checked speaker wiring to make sure right/left and ground/pwr isnt switched around
Last thing I can think of is to buy an optima yellowtop, but I dont see the need for that as its not even the sub thats doing it. I'm convinced there is a bad ground somewhere int he vehicle or some sort of other electrical problem somewhere.
