Looking into upgrading my car audio but not really interested in something that has overpowering bass.

Want to spend about $700-900, already have the head unit/radio.. (not really sure if that budget is possible..)

Still need amp.

The radio I have is http://www.amazon.com/Pioneer-AVH-P3300BT-5-8-Inch-Bluetooth-Receiver/dp/B004HW6F7O/ref=sr_1_1?s=electronics&ie=UTF8&qid=1329095078&sr=1-1


Car is 1999 Accord EX Coupe V6

Any better suggestions on speakers, sub or what else I would need? Need help on an amp as well. Paying forum gold for honest help.
