Anyone have any recommendations? I've got a sport model so I'm not even sure if it's possible to hook up a sub to the existing unit. Regardless, I'll most likely be going aftermarket anyway. Thing is... I don't wanna fill up the trunk area with a stupid box. Sort of defeats the purpose of having a hatch if you ask me. I'm coming from an MSP which had a really nice enclosure on the top area of the trunk. Trunk was still useable and the bass was pretty solid considering. I'd love to be able to put something similar into my MS3.
