Didn't know where to put this so if it's in wrong place tell me....anyway I was putting a sub in with my Mach 460 and had everything going good but a friend that was helping hooked the neg term back up to battery then hooked neg and power to amp then put fuse in at the fuse block behind battery :bash:. Now after he hooked up sub it had no sound, I know the amp and everything else I'm useing works cause I took it out my wife's BMW at the same time. Do you guys have any ideas what the hell is wrong ???:shrug::fm:
