I live in phoenix and know the guy that owns MTX everybody had his stuff back in the day, had, JL is just better in sound quality and probably power the thd at rated power for the MTX is 1 for the JL it is >.05 which one would you buy?
JL is so much better and unique. They will run at a costant wattage no matter what situation you put it in. It will cut off your car to pull the 1000 watts if it has to. Other amps will cut your watts short if not given enough power, that is why it runs at 1000 watts no matter what ohms you put to it.
