Professionally tuned and installed 10" MTX TC710's in a ported Sledgehammer box. These subs hit very tight and add huge audio range to your sound setup. They were only run for about 3 months (babied the whole time, no SPL tests or whatever) before I went to a new car that I did not want to install an aftermarket system in. They are in great condition, the white dots in the pic's are just dust (should have dusted them off before taking the pic I guess).
