This thing was perfect in my Jeep. Sounds AWESOME while it worked. Had it in the Jeep for over a year, and like so many others, the amp blew. This makes the thing useless. You have to get the amp replaced (~$90 at a certified repair place) or bypass the internal amp with a different amp. Like I said sounded great when it worked. I have a Wrangler, so no trunk to penetrate, therefore I barely had it turned up ever. It was always set real low, and had a ton of bass.For a throw away component, it is way overpriced.
