Ok, I have the boston pros 6.53 component set from when I used to compete in USAC in 2000 and became the sq points champion. Anyway my car got broken into and all they stole was the subs and amps in the rear and my passive xovers were mounted on my amp rack. I really like my boston pros 6.53 speakers and plan on putting it into 1980 chevy pickup which I am customizing but I seem to not be able to find the proseries 6.53 xovers. So if anyone has a set of those xovers for sell I would like to buy them. It would be cheaper than buying whole new component set and wasting my speakers I have now. Thanks.
