I had a powered sub that was an old MTX unit... and it was perfect for my XJ... I ended up upgrading it with a 12" Alpine Type R w 500w... and that was even better for me for the occasional want for harder/louder bass.... But when I build up another trail only rig, the MTX will def find it's way into it again... But I might see if I can't manage to fit something like this Bazooka tube into my convertible, thanks for the review, and look forward to hearing more about what you think after more use!!
