Marine Powersports Nautic 2 Channel 400 Watt Maximum Power Full Range Class D Amplifier with PWM MOSFET Power, Black

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!

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 little amp for the price. Easy to hook up. Compact. Powerful. Using it to drive the subs under my driver and passenger seats in my stinger.

Pack a clean punch to my premium Kicker marine 6.5" in my golf cart

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.

What a very Powerfull Amp 4 its size I call it the Little Giant Titan.I am running this Mbquart NA400.2 with my Mbquart Tower NH-1 8inch and sounds super Crisp and only turned up level half way.This is a prrfect combo.Thanks Mbquartz never lets us down.

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.

I installed this on my Yamaha Eluder motorcycle to help clean up the sound. I wasn't looking for louder sound, so I have my gain turned all the way down. It did clear up the sound to a noticeable level.

Works good, decent power, fantastic small size. I put this in my 2015 Tesla Model S to drive the front door speakers (Infinity Kappa 63XF) and they work great. The stock stereo was weak and so I needed an upgrade that didn't pull too much power. This is a nice compact unit that is power efficient.

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.
