I can't give up any of the seats unfortunately:/ it all has to go behind the seats and I would really rather stay away from a blow through if I can.... That's why I was thinking maybe 3 good spl 10s stuffed back there or something? If spl 10s are even a thing for my price range lol? And I'm not talking about competition burp sol but I want more than just load, I really want to shake as much asphalt as I can haha and I know I'm not going to be getting something just ungodly for my price range but I just wanted to see what other people had come up with because I know there is a lot of us out there in this predicament
