I have a Panasonic CQ-DF583U which I personally installed into my 1993 Honda Civic DX. I recently bought and installed two 12 Kicker Comps and a Kicker KX150.2 amp. At various times out of nowhere, the 7.5 backup amp in the engine blows which cuts the power to both my deck and amp. I've never had this problem until the amp and subwoofers were hooked up. Why would the backup fuse keep blowing at random times?

 

perhaps loose connection someplace ?

 

Did you get the right kind of Amp kit for the wattage that you have?

 

How big is the fuse on your amp and how big a fuse is under the hood??
