Great value

I highly recommend this product, especially for clean mids and highs...

PROS... the unit delivers clean sound and no type of engine noise, so far reliable.

CONS... the only con if it matters is the size of the unit. Pretty big amp for the purpose of mids and highs.

Best amp

By far one of the best amps I have ever owned. Has all the features I needed and didn’t break the bank.

Sounds great in 2014 Toyota Tundra Crewmax running 2 sets of pioneer TS-A1606C components.

Have this amp running 2 sets of Pioneer TS-A1606C components for the past 3 weeks. Sounds amazing. Speakers will handle 300W and this will push 125W per channel at 4ohms. Running amp off EQ. to clean up the stock radio signal on a 2014 Toyota Tundra Crewmax. Can't believe how well this amp pushes the pioneers at this price range. I was shooting for SQ and I am not disappointed.

MB Quart ZA2-1000.4 (ZA21000.4)

I am using these amps to power my front and rear speakers in my 2004.5 Dodge Ram 3500 Quad Cab. I have them running in a 2 Channel configuration and split for the right and left sides. These amps rock out with the best of them! The sound is clear and bright. I ran these briefly without my crossover and having the LPF/HPF was very nice. No worries about my components getting the wrong signals! The only issue I have is that these amps do generate a lot of heat and get very warm very quickly. Other then that, I would highly recommend these amps.

MB Quart ZA2-1000.4 (ZA21000.4)

I'm still playing with this amp but it sounds good pushing 4 Alpine type R coaxial speakers with a 125rms there is a lot of ability one the amp it self for controlling the sound production. This is not my first MB amp but it keeps with the bar the products have keep for it's self.

Good Amp for the highs

After adjusting the settings I was pleased at the subs quality the amp produce. I recommend this amp for those who are looking for a budget amp that produces good sounds.

So far so good!

Setup with 4 Pioneer’s speaker and Kenwood Excelon din cd player. Free Belva Amp Kit BAK44 is a big plus. Couldn’t be more happier. Solid performance, musically good. Need to pay more attention on amp setting to optimize sound quality. Overall it is a very satisfying product.

So Far So Good - 1 month

I have this amp pushing a pair of Polk 6.5 MM1 Components and a pair of Kicker KSS670 Components. They sound amazing. Crystal clear highs and surprisingly strong bass. I do not use a separate sub woofer as the components reproduce as low as 35Hz - low enough to feel it.
