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.

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"?!

Solid Connections

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.

Don't Forget The Amp Kit

Remember, you cannot install an amplifier without an amplifier kit. MTX recommends using a ZN5K-04 or ZN5K-08 to power the THUNDER75.4.
