WHAT OUR CUSTOMERS SAY!

Like what Thomas said this is also the best amp I have purchased in a long time. I went from a cea compliant 1200 watts rms @ 1ohm amp to this small little powerful beast and i must say this thing 1000 watts at 1 ohm beats my old 1200 watt rms amp by far and the bass quality running it at 1 ohm is truly amazing!! and it gets warm but not hot and that's normal. this amp made me want to get into system building for a hobby all over again thank you mtx!!

I have been a dedicated Rockford Fosgate amp user since 1992. I recently purchased an MTX 500 watt mono block and in the words of Rapunzel, "I am never going back." MTX beats RF on price, specs, customer service and warranty. I wish I had found out about MTX years ago.

eric 8/7/2013

Wow! This amp has plenty of sharp clean pop on the bass end and clean crisp highs. This brand was recommended by a installation tech at a store that did not sell MTX. This is after a Soundstream Rubicon amp last three months and needed to be sent back twice for repairs. There is no comparison in the sound quality with the MTX high years ahead! ...Did I say 'Wow"?!

The terminal block of the THUNDER75.4 uses set screw type connectors for both speakers and power/ground to make it easy to rigidly connect your system's wires without having to buy additional installation parts.
