So I canceled the infotainment system mainly due to price, and I've been considering aftermarket options for music/backup camera. I understand I will have to add some sort of larger speaker than what is offered with the SS, but I really want my sound system to vibrate the people in the car next to me when I'm listening to really based out music. My friend (quite knowledgeable about cars) told me that the open-air cockpit in the SS will all but ruin this desire because there is no closed air chamber to hold the vibrations...or something like that. I don't really want to give up one of the cargo compartments, but I suppose I might be okay with that if it really gives a difference. I'm rambling...any suggestions on obtaining high bass and the body-rumbling vibrations that come with a really good system in a closed-cabin vehicle?
