    Marathon MA-4050 reviews

    MA-4050 Stereo Power Amplifier (800W/Channel @ 8 Ohms) is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Bullet Proof Had it running for 11 hours straight at low to medium levels and it didn't cave in. Highly recommend for dependable power. Unlike the digital amps, this monster has large capacitors and heat sinks. Your best bet is to run the amp with high quality and high power rated speakers. It will annihilate cheap speakers. I would say a cabinet that handles 250w RMS is a good start. I sometimes run 4 speakers at 4 ohms and it doesn't blink an eye. However at 54lbs its not a lightweight.
