When I picked up this poor thing I had to re-solder the voice coil wires back on. It was really beat up and covered in liquid nails... yes liquid nails. I tossed it in the jeep and hooked it up to a class A 10.0 just to break balls and beat it up. Its surprisingly LOUD and takes all sorts of abuse.
