powerful yet very clean output great for high quality 6.5" or 6x9 speakers
Pack a clean punch to my premium Kicker marine 6.5" in my golf cart

Great sound quality.
This little thing packs a punch. I have it on my RZR and it’s small enough to hide under the hood area and has more than enough power for my needs. I run this one with 4 Polk speakers and it sounds really nice. Would recommend!

Great amp!
I drop a a video just to show you guys the sound quality of the amp. It is connected with bluetooth and it still sounds awesome. I love this amp. Throws out an amazing amount of power easy to put anywhere. For any application. I used this on my Yamaha wave runner. I did the install myself and like I said before you can put it anywhere. This is a must buy. Especially for the price. Great job MB Quart!

Gets It Done
I bought two of these amps for my 2011 Dodge Ram for under the rear back seat; one for the 6x9s in back and one for the 10 inch subwoofers in back. Not an overly loud amplifier, but enough to provide good sound for inside the cab... plus the Low Profile design fits nicely underneath the rear seat with plenty of room left over for other item. Sounds great and no issues so far.

Small but does the job!
2 channel power for boat speakers - perfect for small boats where you don't plan to have more than 2 speakers. This is powering a pair of mid-level JLs on a 20' boat and it's making them sound more than adequate.

Awesome amp
For the price I was surprised. It powers 2 100w RMS DS18 speakers in my canam x3. It gets very loud and sounds great. Can't beat it for a clean simple install , especially at this price .

Drawing way to much amps
This is my second MQ amp. My sub amp is amazing. This one draws way too much power. Blows through 30amp fuses and heats up the - line to melting point. The unit was an open box item Amazon sold. I think Amazon sold a broken unit that caused a lot more damage than the unit cost.
