I said in my post you probably wouldn't have to take anything off if you can reach in the back. I just suggested taking anything out that would make it easier.

And how do you replace the front speakers with out taking the door panel off?

As far as suggesting speakers, I love mine. I prefer Alpine to Rockford and would have gotten Alpine type-r dual voice coil subs if they weren't so darn expensive. All my audio is in my sig.

If you want to find out what you like go to a car audio place and play around. They should have a board that lets you test different system set ups.
