Posted December 16, 200816 yr i have stock electrical, just one 4 gauge run to my alpine pdx 1.600 amp (600rms, 730 peak), but my gauges/instruments dim down to about 50% and my headlights dim terribly. will the big three in 1/0 or 2 gauge solve this problem? i have a 2003 vw passat, im pretty sure my alt does 90 amps..
December 16, 200816 yr have your alt tested first! chek your grounds, and make sure your connecting on your cell is good.... how big off a cell is in there anyhow?

Both cars have simmilar electrical systems if not the same so I think you should check your alt and/or battery.
