Well, I thought I had a well-matched system, but I blew both of my 10's last night...

Pioneer DEH-P9300 head unit
Pioneer TS-A6865 6x8's (4)
Pioneer TS-W254DVC 10" subs (2)
Pioneer GM-X564 480wx4 amp

I've got two channels of the amp going to the two door speakers and the other two channels bridged running parallel to the subs. The rear deck speakers are just running off the radio signal.

Oh well, I guess I'll just swap them out. The system sounded great until this......

 

Turns out I had wired the subs wrong to the amp, and fried one half of one channel...
