yup,,they are bad to the bone,,i have sat in mtx official boom van,, it had to be plugged in,,,i had to admitt it was powerfull,,,we came jamming into a local big sterio shop,,my buddy has a precision power amp pushing 1200 watts,,and 2 jl audio w7s<~~and its allmost too loud,,,but the mtx guy was impresssed with the power we had,,so he had to show off,,and made us sit in the back of his van,,i had to say,,we were alittle out classed there,,lol,,but it was too loud!,,1200 watts with JL audio w7's are plenty for anyone who still wants too keep there crap in there guts!,,lol
to run 1200 watts safely he had to add 2 zap caps and 6 gauge weilding wire leads and a hi output alternator
