For a BOSE, my 03 cl-s sounds like pooh after i drove a TSX loaner...
what speakers work best in the CL with the BOSE? Is there a factory SUB i could add?
any help would be great, thanks

 

The AV forum or the group buys has a set of replacement speakers for the CL, sold by a guy on the site. There seems to be good reviews of the speakers if you don't want to spend too much time/money/effort on changing a lot of stuff. These speakers do fit the stock fictures and wiring.

Here's a post about the replacement speakers:

Here's the post about the group buy, here you'll also find links to reviews of the kits:

speakers are not going to make a difference unless you change the headunit or get an external amp
