the new mtx subs are real nice and fairly inexpensive to get into and they're amps are very good matches as well. my buddy just got one 10" mtx 7500 and it bumps hard! sounds real good. talked to a guy at a car audio shop yesterday cause i haven't been researching in about 5 years and everything has changed but he told me the mtx subs are now even more reliable and stronger than JL. this is due to the voice coil design and material used to create it.
