When I was looking to improve my sound system I couldn't find any reviews of these. I've been running the system for two months. I bought the amplified version from crutchfield. The first unit mtx sent me had a blown sub, crutchfield has great customer support and had a new one out to me in 3 days. The 2nd one has run perfectly for a month until the amp malfunctioned, crutchfield has another one on the way for me. They sound really good when working. If you exclusively listen to rap, it may not be enough bass, but still sounds pretty good. Even with the top off it sounds good. Fits right behind the rear seat as advertised. Hopefully the third one works.
