User Reviews about MB Quart Discus DSC4125 500 Watt A B Class 4-Channel Amplifier

Got this to replace a RF amp that was sounding like crap during my last install. I run three amps, two are JL Audio driving my main speakers and subs and the third that drives midranges and the rear fill. I'd been installing away and was over budget so when I found out one of my amps was toast I was in a real predicament money wise. Found this one, checked out the reviews and bought it - I could get it fast and the price was right.

Great amp, especially for the price. Good sound quality - rivals the JL Audios I have. Price - superb. Volume - plenty. I'm not pushing huge wattage through it, so I can't say how it works at the limits of its ability. For what I need it is most excellent. -- Bitchin' amp, especially for the price

Using this amp with a pioneer 910 head unit powering four mb quart premium component two ways in paralell on channels 1 and 2 @2 ohms and a 10"kicker sub bridged on 3 and 4 @ 4ohms...Sound is awesome, Versatile connection combinations since channels are seperate either 2ohm or 4ohm or a combination of both. heat has not been an issue...Tin the end of your wires at the connections and give this amp a really good ground..and you will enjoy really really good sound!!! -- Excellent
