I'm selling my 2 10" MTX RoadThunder and 200 watt MTX amp (MTX RT202). The subwoofers are under 1 year old and the amp is 2 years old. I had these in my old car but decided to upgrade when I got a new car. They have a nice sound and haven't been worked very hard. The subwoofers are in a generic sealed box with mesh protective sheilds covering them.
I can find the specs about the subwoofers and amp at a later time, if you want.
Make offer. I have the box for the amp and perhaps for the subwoofers. I'm not sure how much shipping will be.
