The GLI/GTI's have a 120a alternator. Im running an Orion 8004 and noticed a small amount of dimming, im thinking of doing the big3 next.yeah, i think it's 140 or 150. but lately my interior lights have been dimming and i'm only running 1k watts. when i add the comp amp, it can only get worse.
i'm looking for anything bigger, maybe 200 amp?
