Sounds great! Obviously I'm not getting the full affect of the subs and amps because of the factory 8.4a but for what it is it sounds great. The deck REALLY limits it! It's tuned to be crystal clear and sound good. The bass knob REALLY helps and obviously the cleaner the recording of the music the better!
Just a side note....the owner of the shop where I had it done is a little jealous! He has 4 10" JL TW3's but is running the 5 channel amp to them. They're WAY under powered! He'll be making some changes in the near future!
