MTX Audio THUNDER75.4 Thunder Series Car Amplifier

I've been using MTX amp's since 1996. They always put out more than they advertise. I power the front(Mb Quart 6.5in. components) and the rear (Focal 6 X 9) with the Thunder75.4 and an MTX Thunder 280 for the sub. Fantastic sound. Kenwood head unit

I'm an mtx fan so I like their products all of it,I use these two four channel amps to run my polk audio 6.5 door speakers and my polk audio 6x9's in the rear all the speakers are 200watts each and they sound awesome😎😎😎unreal love them😍

Really great amp for entry level. Easy to install, sounds phenomenal. I have 4 kicker speakers powering thru this and they sound great. Paired with MTX terminator amp with 2 12 inch subs. I’ve put 2k miles cruising around just listening to music.

This amp is decent, but it does not put out much power. It is class A/B so the sound quality is there- however this makes the amp run hotter than a class D amp would. Make sure you give it plenty of room to breathe.

Awesome amp! Sounds great and looks great with full metal chassis. Setup is relatively simple with all the normal adjustment controls you would expect. Speaker and power connectors are all screw compression which is extremely nice and time saving when hooking up. I feel like the red section under he MTX logo should light up though just for aesthetic appeal (or maybe it does and I just can't tell =/ ). But otherwise no external or functionality complaints.Internally is a relatively basic class A/B PCB layout designed well with minimal raised through-hole components. Only raised components are 8 driver transistors for each output FET, but still seem solid enough to not suffer from too much road vibration. The (red) PCB itself appears to be of high-quality with very beefy traces on the power supply side which I really like to see instead of raised bus bars. The only thing that I don't like about this amp is the power supply input & output Shenzhen Acon filter capacitors. Really would have liked to see some Nichicon or Rubycon caps here. Especially for the locked-down $200 price practically everywhere you look for this amp online. I have to take a star down for that because I see these caps in other lower quality amp brands as well and sort of a disappointment. Problem with these Shenzhen market caps is they aren't always the greatest quality. They may work well now but the guarantee 5 years down the road with usual wear and tear is debatable.All-in-all it's a great amp though! Definitely recommend it. Always been a fan of MTX and will continue to be! Just use some slightly more reputable filter caps please. =)

So far there’s been no clipping and it’s powering to six by nines in my front door to 6 1/2 in my back doors with tweeters. It does get a little hot though.

Works perfectly.

I paired this 4-channel amp to two Alpine-S 6.5" speakers and two Alpine-S 6x9s. This combination brings a broad spectrum of mids/highs & lows to the vehicle. Makes the factory Bose and Infinity stereos in my other vehicles sound sub-par. This amp is money well spent, you won't regret it!
