I swapped out the stereo for a nicer unit with more controls and satellite radio and I-phone controls. I also added a 10" sub and 500w amp. Amp is on top of stock amp location where foam was. No overheating issues so far. Went with a Bazooka tube so it would be easy to remove if I needed to stuff a suitcase in the trunk.
I added the inline resister on the mids and highs. I kept the stock 6.5" subs. Adding the 10" really fills out the sound when the top is down. Folks next to me can feel the bass I have new Pioneer premier 6.5" and tweets with a new amp to replace the infinity stuff when Mike has time to install.
