i have a pioneer dehp-3000ib deck installed in my cavalier with 4 after market speakers: Polk DB461 and DB691. the 6x9s sound decent but when i put all the power to one speaker, they sound amazing. would a 2 channel amp placed on the 2 6x9s make them sound better?
P.S. The 6x9s have 100 watt rms and the 4x6s have 40 watt rms.
im pretty new to car audio but the speakers were amazingly easy to install. Thanks for any help.

I'm assuming you mean one set of speakers and not a single one based on the "They sound amazing" statement.
The radio has a 4 channel amp built in to the unit, you are not changing any power levels by running the balance/fader controls front to back or side to side.
What it sounds to me is you may have the polarity of one or more speakers reversed and they are cancelling out the sound, you will notice that predominately in the bass region, if you play 1 speaker and get your ears accustomed to the bass response, when you bring in the other channel the bass should intensify, if the bass gets lower instead then one of those speakers is wired backwards. The same thing can happen with front and rears, listen to the front ones and the bass is nice and bring in the rears and it goes away instead of getting more bass.
I would suggest getting a multitester that has a continuity tester on it, pull and disconnect all of the speakers, and pull the radio and disconnect the radio from it's harness (not from the car harness, but the harness connector that plugs into the radio chassis instead) and get your radio's wiring diagram out and use the continuity tester to test the leads from the harness connection to the speaker terminals to determine the wire's polarity. You only need to test 1 wire at each speaker to determine if it is a + or - lead from the radio then hook the speakers back up accordingly. Once done correctly you should be even more amazed with all 4 going.
