I'm looking for a sub-woofer that I can fit somewhere out of site in the cabin. I would get a conventional trunk system, but my trunk is frequently full as I travel a lot. I know there isn't a lot of extra space inside of the cabin, but I'm hoping one of you has found a solution! I don't need to rattle windows, I just want the low bass in my rap music to sound more full. Also, price isn't too much of a concern, but obviously cheaper is better! Thanks guys, hope one of y'all comes through!
