I've recently purchased this MB Quart 4.60 4 channel amp and installed it with the MB Quarts 216 component system into my 2005 Mazda 6 GT.After trying to run this amp in series with a line level converter from my stock Bose head unit and Bose Amp I was totally frustrated(Didn't want to lose my steering wheel controls that are run through the stock Bose amp but the Bose head unit,bose amp,scosche line converter and Mb Quarts amp didn't play nice-nice with one another!!!)I yanked out the Bose stock amp and line converted and then wired this amp directly to the Bose head unit as it outputs 2 volts(Line Level) which is plenty for this amp.All I can say is WOW!!! At 1/3 the gain on this MB Quart 4.60 the MB Quart component system can literally over power the car.Due to the MB Quart 216 component running the tweeter and 6.5 inch driver in series the amp is putting 120 watts per channel to these speakers at 2ohms...This amp powers these speakers to the point that I can actually overdrive the speakers with less than half gain(Almost blew out the tweeters).After settling with about 1/3 gain on this amp the speakers will play to full volume off the Bose head unit without any audio distortion than I can hear.Even at 1/3 gain volume and cranking up the head unit I get headaches and ear ringing thats how powerfull and efficient this amp is.Also noted was that this amp didn't even get warm.It ran cool and flawless through all the testing I put it through so far.Another excellent buy from Amazon and another high quality excellent product from MB Quart... After owning this product for a year I must come back and warn customers that I have had some issues with this amp. First off I had to twice take this amp apart to clean the multiple channel switch due to different speaker cutting in and out.Read more ›

I have this amp powering the 4 Infinity 5032 speakers in my Jeep Cherokee. These are only 5.25" speakers so all I expect from them are some mids and highs, and this amp really brings out the capabilities of these speakers. Another MB Quart amp is driving a 10 inch Rockford sub which provides all the bass I need.

The amp has all the settings you could need and runs cool. I would definately recommend this amp.

I have this 4 channel running 2 sets of Polk Momo's and I must say that I am impressed with the sound quality although its a bit underpowered for those speakers. However, the amp still performs well, and I am satisfied.

I have always liked MB QUART not as good as they were about 10 years ago but still good quality for the money.
I chose it because i have had this brand before like i said about 10 years ago and they were superior,wonderful quality.
When you are looking for a good 4 channel amp that wont cost u an arm and a leg this is the amp for u

This seems like a good little amp, especially for the money. I'm just running 2 pair of 6.5's with it but it has all the bells and whistles for x-over points and adjustments. Looks very nice too.
