Well, which ones you wanna replace? Dash, Sail Panels, or both? At first I had 4x6's and 6x9 Pioneers, which bolted right up (the 6x9's pushed on the sail panels a little bit) and to tell you the truth, they kinda sucked. Full blast they were great but when the vol. was turned down, they sounded like they were popped, blown, and distorted. I have Polks 4x6's and 6x9's in now, and they sound great without an amp. Like the Pioneers, they bolt right in. FYI if you didnt know what sizes go where, 4x6's go in the dash and 6x9's go behind the sail panels. As for the wiring, i don't think its necessary to replace the entire wire from the H.U. back. Your gonna have to snip the ends off at the clips off the stock speakers to make aftermarket speakers fit. It all depends if you wanna amp the rears.

Thats just my recommendation and my 2 cents.

*EDIT* I have T-tops as well, and when they are off, they sound great !!!
