Speakers

Hello everyone. I have a 2001 Silverado Z71 4X4 that needs new stereo speakers. I would like to get the Bose speakers for it but I understand that this is not possible. Anyone have any suggestions for the best speakers I can replace the OEM speakers with?
Thanks

good aftermarket brands. alpine, infinity, mb quart, etc.

Check out Infinity and Kenwood, also maybe Pioneer and Sony, or Rockford Fosgate.

The sizes are 6.5" in the front and 4x6's in the rear

alpine type r, not to expensive and sound great
