    Amp Fuse Blowing

    I have one cvx 12 and a rockford fosgate 300 watt 2ch amp. i bridged the sub. now the problem wen i turn on the amp without the sub hooked up it works. it works wen the sub wires are hooked only to the amp. but once i conncet sub to amp the fuse blows. idk what the problem is or where the short is, i took the sub out of the box and checked all the connections it still blew the fuse. HELP PLEASE

    have you checked the subs voice coil with a ohm meter? it sounds like the sub might be blown.
