Bose system subwoofer size
 

Does anyone know what size the sub-woofer for this is? What would a good replacement be?

Does anyone know?

I'm not sure the specific size - but having just done a hunt this past summer for a sub - I can tell you there aren't a lot of options out there that fit cleanly without some major modifications - or footwell loss.

I ended up with a self-powered Kenwood that fits very nicely under the passenger seat without any trouble. I have an upgraded head unit and no amp, so was a very simple set up.

If you have the bose MOST system, might be more complicated than a simple plug/play kenwood sub.

I was hoping for a plug-n-play replacement that sounds better.
