I find on these forums people praise and run non mainstream amps cause they're cheaper for the same results. I used to have a mtx thunder 2300 (rated at 600 rms but put out closer to 1000 rms) in white and chrome, rare amp for 1995 and a mtx 6500d(rated at 500rms but put out closer to 1000 rms). Mtx makes solid equipment but there's sooo much competition out there and there prices can't compete with the non mainstream, for the most part
