I've read that all you guys definately are against mixing brands of subs but I've recently inhereted a 92 gmc sierra and there were 2 10" mtx 6000's in the back already. I was wondering if I could use inline crossovers and the amp to make it a (bandpass?) range of 70-125hz (maybe higher? comments?) or so and use my other sub (kappa perfect 10.1) for <70hz and would this sound okay? I figure I might as well use the extra muscle if its already there at my disposal. The other speakers in the car ar 4x6"s (unsure of the brand, havn't looked yet).
