Is there any Bose upgrades I can get for the preimiem package stereo. The sub cannot handle alot of power , do you know of any upgrades?

Thanks

 

There's no easy answer for this:

Your gonna have to realistically buy an amp, a LOC, and a sub to do it right. While your at it, might wanna redo all your speakers as they are kinda weak. It wasn't cheap, but its well worth it.
