They are crap, so are the Rockford Fosgate that are the same with a different label. Seriously, they don't hold up. That's why there are so many refurb ones out there for cheap.
ugh, I wish I had seen that before I upgraded to an xmd4. the remote would fit in place of my old clarion remote pefectly. I dont really like the xmd4, it cant even play mp3's
We have the MB quart in our boat and love it. It has held up fine, rarely skips, and sounds great. I am very happy with it. If you have any specific questions let me know.
