I have a 95 GLE that came with the BOSE system. I have replaced the head unit and added an amp and subs. NOw i want to replace the speakers starting with the doors.

Will new speakers just drop in the old spots. And can i use the existing speaking wires. Also what size speakers fit best. I have seen 6.5", 6.75" and 7" recommended.

Since getting the HU. amp and subs my subs dont seem to work correctly. It seems when i try to adjust the bass it goes to all my speakers and not just the subs. Is there someting with the BOSE speakers causing this and will replacing them eleminate the problem.

Thanks
