Would it be possible to change the sub in a car w/bose sound system??
 

Just wondering if I could add 2 10' type x subs or replace the current one with those. depending how it is. I heard it's not possible but i'm just wondering.

Bose is just a welfare system that you can definately add on to or remove completely. We've installed many real subwoofers to Bose systems. You will need a high level line output converter if you are going to take the signal from the oem sub output.

huh, well thanks.

Try 256 Motoring...they might have the enclosure spec that you're looking for...ask them for whatever else, they might have the right answer for you.
