MUD100.2 Two OHM Amp

This Amp mounts better than the Harley brands. Because it has a small size it fits better and routing wires becomes easier. Amp has more power then I could imagine. This Amp is a far better value then advertised.

Worked Beyond Expectations

I knew I would get higher volume but it also helped separate Bass and Treble in my stock Harley radio. It was so compact it fit better than Harley and Hogtunes units. I would recommend this because it is $400 cheaper and sounds better then the system my buddy bought from Harley.

Another Unreliable Made in China Product

I am currently on my second replacement of this amplifier. The first one sent to me did not play any low-frequency sounds from either speaker, switching between HPF, LPF and Full made no change in the frequency output of the amp. The replacement I received only played out of one of the two channels which were confirmed after multiple tests. Of course, this was only discovered after the full install was complete as I only tested one channel for frequency response prior to installation. I am currently awaiting a third replacement which will be tested before being shipped. Overall this has been the worst experience I have had with any brand of audio equipment. Great design, awful execution.

Exactly what I needed

I was a bit worries about picking up this amp, because I saw that it had few stars on Amazon. But this amp definitely deserves 6 stars! It does exactly what it is advertised as doing, provides good sound quality, and has never cut out on me. I couldn't be happier!
