The THUNDER75.4 is a 400-watt RMS amplifier designed to be installed in almost any vehicle due to its small chassis size. Its power capability and wiring versatility makes it a perfect choice for running multi-channel speaker systems without compromising musical output or quality.
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"?!
This amp features a Class A/B circuit design that delivers high fidelity sound output meaning you can enjoy your music as the artist intended it to be heard. The multi-channel design also means that you can configure you speaker system the way you need without running out of power or functionality.
We use surface mount technology to help create the compact design of the amplifier and improve its reliability and resistance to vibration. High grade components are chosen for their quality and to ensure the amplifier delivers maximum power output when you need it without loss of audio resolution.
In addition to the circuit design, we’ve also added the features you need to fine tune your system sound such as the built-in variable gain and crossover controls.
Additionally, we know how important the speaker and power connections are to a properly working sound system. This is why we use set-screw style terminals to provide the most secure connection possible which minimizes any power loss while delivering all the power to the amplifier and to the speakers.
Compact Design - The small footprint chassis allows for installation in space challenged vehicles
Surface Mount PCB Design - Decreases chassis size, improves layout efficiency and increases vibration resistance without sacrificing performance or sound.
Variable Butterworth Crossover - a 12dB/Oct crossover that allows you to set the frequency your speakers will play down or up to
Triple Protection Circuitry - Thermal, DC Offset, and Short Circuit Protection circuitry ensures the amplifier will protect itself in the event of a problem
Extruded Aluminum Heat Sink - The custom heat sink design maximizes heat transfer away from the circuitry protecting the amplifier
