I have 2 MTX MXS 10 inch subs which are 400 RMS each, and a matched MTX MXA8001 amp to power them. I also have a 1.2 Farad capacitor to help ease the pain on the electrical system. The subs are mounted in a heavy duty Q-logic box made with thicker MDF material. I purchased it all new at circuit city about 4 months ago when i used to have my gay volkswagen jetta. I traded that car in on a new F-150 and i dont really want to put that stuff in my truck so i figured i would try selling it all. I payed a little over 1000 dollars for all of it, it would like 500 or best offer for it. Thanks guys let me know if you have any questions or want pics of the stuff.
