MB Quart XA1-1100.5 1100W 5-Channel X-Line Series Class A/B Amplifier

Nice strong amp. Easy to install and fully adjustable. This was originally a replacement amp that was bought for my son to replace an outdated JL amp. About a year later, some thief stole it and we bought the same amp to replace it. Very clean and the x-over has a full range of adjustments. We ran it in the 5 channel mode and it is currently in a Mini Cooper s with MB Quart component speaker in the front and rear and a MB quart 12 sub. Grear amp for the price and very clean sounding. This amp has a lot of power and you will not be disappointed.

This is a clean, potent amp when combined with the right speakers. Once you dial in the gains to your head unity it will crank out clean, loud sound!Paired with 6x9 Infinity 2-way, 6.5" Infinity 2-way, 1" Infinity tweeters and a 10" Infinity Kappa Sub.

Worked for a little more than a yearThen burnt up

Great amp. I've owned a 1500.1 amp mb quart. This 5 channel amp impresses me. I didn't think there would be enough rms power left to power a alpine type R. new version 1000watt rms. The amp is powering 1 polk component system, and 2 polk 6 1/2" 3 way all are 100 watts rms. The amps sounds Great. The alpine type R is dual 2 ohm voice coil. The amp powers this sub tremendously. Very stable. It's painfully loud when i get to about half volume on some content. vehicle is a 2011 dodge Ram dakota ext cab. Best sounding(quality) system I've owned yet. This is a great amp if you don't have a lot of space and money. I'm really happy with my purchase.Update:6/29/2018 The amp is still running GREAT! I upgraded the front components to Infinity 2ohm 90 watts/rms. I just upgraded the sub to a kicker CompR 12" dual 2 ohm. This thing never sounded so good. Zero distortion. This is clean and very loud. Sound quality is superb. Very happy. If I could find one (mbQuart) that was 800 to 1000watts 1ohm I would get it and another Kicker 12" sub. But I am happy with this set-up for now. well I guess they do have one that is the Z-line. MB Quart ZA2-1500.5 1500 watt, four channel car audio amplifier . So There I go.

very nice, powerful amp. the only downside i can think of is the size. it's massive! the 500 watt, 1 ohm sub channel can probably handle a higher rated sub currently pushing cadence 600 watt 12" 2 ohm dvc in a box. combined with a nakamichi head unit and a capacitor, produces impressively responsive, deep lows. the other 4 channels produce plenty of power and the sound is very clean (focal is130 components). great multi chan amp! i was worried i wouldn't get enough bass without a mono amp, but my current setup is plenty sound.

The amplifier performed well during break in. I used it originally in 4CH mode while breaking in 4 component door speakers. Added 2 12's switched to 5CH. Went through another break in period for the subs. After tuning for the complete system I lost the right rear channel and the right rear door speakers. Further trouble shooting revealed the factory head unit dumped the right rear channel also. SO... I will say I'm impressed at the sub performance and I pushed it to thermal shutdown. The two 12's are rated at 250rms. Not a single issue with the mono side. We will see how fast the turn around time is on the amp. Yes this amp is capable of handling a mid power sound system and I would purchase the exact amp again.

Clean strong amp . Huge improvement to my sound . I'd give ten stars if I could based on quality and price . This thing is running 2 dual voice coil tens 4 component speakers 6 1/2" . All MB quart . Sounds better than anything I've put in my vehicle before . Not louder but clarity is killer . I was one of the kids who needed 4 15" subs with 4000watts lol.

Great amp for the money. Powerful enough to be considered a great simple upgrade over stock. All in one package that gives you good power to run a sub and fronts & rears for not a lot of money. I used this with 4 6.5" door speakers and two 15" subs and was very surprised at how loud it got. I wasn't expecting as much sound as I got. It moved the 2 Sundown SA 15's surprisingly well.
