Has anybody picked up or heard the factory sub in our car?

I have it (2002) - came with the speaker upgrade too. In hindsight I wish I put that money towards aftermarket stuff. Neither the speakers nor subwoofer are really that good. Better than the basic stuff, though...

Looks like you have an 08 - could be the subs are better...

well I had a P3 in the back but took up to much room and I have already upgraded the speakers but now I need a lil more base... what to do
