Sounds awesome! I used to have 2 or 3 way pioneers in the back but one of them broke and I replaced the one with a really cheap planet audio speaker. it sounded so bad I just use the two front ones now and started looking into how to upgrade my system. Pretty much decided I'm going to eventually install a 2 way dsp system using an $80 unit from parts express just for the front using Dayton Audio AMTPOD tweeters and not sure about the mids yet.. maybe something crazy like 2 mids per door with new fiberglass to get rid of that nasty hole in the door plastic, and some 4 channel amp. sub will be Skar VVX-8 which is 400W RMS in a similar box probably and Skar RP350.1D because I just saw on youtube they posted a video of it on the amp dyno producing 378 watts at 1ohm <1%THD with 14.36v and 452 watts of dynamic power with 14.38v
