If all the midrange speakers are dead, then it could your DSP unit or the amp. One test you can do to check your speakers.
Pull the speaker out and test with a 9 volt battery across the terminals. If the cone pops and moves, then the speaker is good. Your problem be with the connection were both door speakers connect. Do the same test at this point, both speakers should make a noise.
