I recently purchased a pair of JBL 631, kicker 46CXA360.4T amp, RCA's, the recommended 8-gauge amplifier power wiring kit from crutchfield, a Kicker CompVR 43CVR122 sub and the speaker wires 16 gauge. Everything went fine until I added the sub wired in series, bridged using 3 & 4 channels as recommended by crutchefield reps. Gains are set at 12 oclock and every since the amp has been going into protective mode. I checked the voltage on the amp before going to protective mode and it reads less than 11v. I disconnected the sub and everything went back to normal. I set the gains at 9oclock with the sub connected and it out out from protective mode. But it doesn't sound as loud as before. I've spent over $600 just to listen to music with the gains set at 9oclock? I drive a 370z. Battery is brand new and the alternator can handle a lot (150). I'm using a 16 gauge wire for the sub btw.
Any help would be appreciated. Thanks
