I'm sure the stereo system will sound good enough to not put in an extra 200LBS!!! into your trunk and completely destroy your weight distribution ratio!!! Thats why I opt on leavin the stereo ALONE!!! Except for maybe the head unit and mids/highs. But I will be keeping factory amplifier for a while and factory sub. I'm pretty sure the added wight of a box, at least one amp for a system (sometimes two depending on voice coils and ohm levels - no need for anymore really cause you don't have enough room in that lil trunk) and usually two subs (per personal preference), would throw off the handling a lil. Thats an easy 100+lbs. in the back transfering the center of g-forces backwards... away from the drive wheels... more tire spin
