My lights dim very badly when my bass hits. I'm running a 1000 watt amp with a one farad cap, aftermarket positive terminal clamp, and an upgraded ground from the ground post on the battery to the chassis. Everything in the trunk is grounded fine. My headlights almost flash like strobes and my indiglo's flash too. The lights on my amp (volatage meter) also flashes. I was thinking about getting a 3 farad cap, but anyone else have another suggestion?
