I have a none-BOSE system in a 5th gen and want to add a sub but do not want a box in the trunk. Even though my car is none-BOSE it has the “cutout” for the BOSE sub.
Did anybody install a sub were the BOSE sub goes? If so what kind of sub and size?

thanks

 

its an 8 inch if i remember it correctly...
u can't use the stock bose amp to run other subs coz the sub on bose is 2 om i think...

 

8inch. You will probably have to trim the metal anyway with some tin snips. More info available if you start a thread in the audio forum.

edit: oops, you DID start a thread in the audio forum.
