In my sig i have a jbl 1200.1, im trying to set my gains again (to push every little 1/1000th of a db out of it). I know my charging system is not up to par with my stock 130A alt. If im not getting a full 14.4 V while im setting my gains, would that affect my setting? Right now its a little under 1/4 of the way up to make sure i dont fry my K's, but im going to try and compete here shortly, and im trying to milk eveything I can out of my system, without dampening (5K college bill just came). Can a sub-par charging system affect my gains?
