I bought a 1000 watt amp and just attempted to bridge it to my car sub but instead of running the positive from one side and the negative from the other I used two channels and ran positive from both channels and negative from both channels to my 12" sub. Now it wont work and I've tried resetting it after I fixed the bridge.havent checked the in line fuse. Any suggestions?

    You failed to read and follow the instructions. 

    You deserve the consequences.  




    Bridging an amplifier requires first that it was designed for such operation. 

    If it was, it will have a physical switch to put it in that mode. 

    No switch, no bridging. 


    Also, the speaker - terminals are NEVER used in bridged mode. 

    The load is connected ONLY between the two speaker + terminals. 


    Take your damaged amplifier to a repair shop 

    and have it put back into operable condition, 

    then have a professional car stereo installer connect it for you.

    Thanks for the response. If I shorted the outputs did I fry the amp? 😳 I got a two year warranty on it so I can go get another one I think but if I can just fix it I'd rather do it myself. Thanks a billion

    You shorted the outputs.  Might have blown output transistors or something like that.
