I have 2 mtx 6000 15's. One of them needs the voice coil wire sautered back on and the other one is blown. I have called MTX and it is going to be $190 to fix them and they will send 2 brand new subs back to you. All you have to do is pay to ship them to MTX and include a money order or call them with credit card and pay the $190 and they will send back 2 new ones. I have the address to send them out. I don't have the money. Someone make me an offer to get these out of my closet. They are still in the factory boxes with all paperwork.
