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 This was originally a replacement amp that was bought for my son to replace an outdated JL amp.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.

This thing is amazing! Well built and solid. I was on the fence with the overall lack of reviews around the internet but I am so happy with my purchase.I have it running 4 speakers and a subwoofer and it is clear all the way up to full volume. I am not able to comfortably play music past half way at a modest gain setting.I didnt feel like I bought the claims it has but I can tell you I love it!

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.

Love this amp. I was in the car audio business for 15 years. MB Quart was always a well made, good sounding product. Straight forward install, and sounds great. I replaced all the speakers in my 98 jeep TJ with MB Quart also. Amp came on time brand new in the box with all correct paper work. Great product, would recommend to anyone.
