Conclusion: Installed this in an '84 Fiero and it fit flush - no clunky adapters, which is hard to do with such little space. The lack of a CD player makes this deck very shallow. The Bluetooth is seamless - my son was playing music through his iPhone instantly.
Conclusion: I have had these for 6 months now, and they work great. They wont add bass or anything, thats what my 12" kicker is for but for the highs and mids. It was amazing. I heard things with these and the other pioneer speakers that i never heard before. I highly recommend and would buy them again any day.
