Any one can tell me how to open the door panels to replace speakers?

Its about the same as other doors. Someone, I think on this site, has already posted pics. Do a search.

But basically, pull off the silver covers on the handles (pry a but carefully, then they pull out). Then unscrew. Pry out the window switch panels, remove a screw, then pry off the door panels.

Fronts are 6x9s, rears are 6.5s (but will need an adapter).

Thx rogueboy for the reply. What do you mean by adapters?

Well, 6.5" speakers wont directly fit. They are a bit too small. An adapter will help fit them.

I replaced my stock speakers with xplod 6x9's. They fit perfectly. No adapter was needed. But, the speakers are 300 watt, and are performing really low. I have bass on 5, but can't feel it. The stock speakers were much responsive. What make or model speaker work with factory cd-player.

The stock speakers are 0.2 Ohms, 20 watt each. Total power must be 80-100 watt for the system.

Is there any after market speaker to match this low power?
