hey man I happen to have some experience with those speakers the stereo store I used to work for carried jbl speakers. We had several people have the same problem. The answer is actually 2 things. First a Jensen amp is not designed to handle a 2 ohm load (if you have your speakers paralleled that is what the amp sees) also, If you have a meter, you will be able to test the actual speaker resistence and you will probably find that your jbl speakers say they are 4 ohm but in fact read less in turn putting more stress on your amp. My suggestion would be to put your amp in stereo or series your speakers. Wire the positive from one sub to the amp and the negative from the other sub to the amp, and wire the remaining pos and neg together on the speaker
