MB Quart Marine Powersports Nautic 1 Channel 400 Watt Maximum Power Full Range Class D Amplifier with PWM MOSFET Power, Black

Does a great job of powering a little 8" sub. Probably work for 10-12" also. Small so it fit on a little box and it has built in crossover and external sub gain.

I used this to power my 10" R2D4 Rockford fosgate sub in my Polaris Rzr 1000 (under-dash enclosure). So far, no issues. It has not let me down after the initial 100ish miles on the trails. The bass boost knob is also nice to have.

Delivered as expected, 10 inch kicker comp r sounds great hooked up to this Amp!

Replacement for exact same amp hopefully this one works better. Very easy plug and play setup.

13 Electra glide This little mofo kills it . I’ve head unit 5.25 kickers in fairing and 6x9 kickers in the bag lids. I was blown away how load this little amp is louder than my muddies same set up with Rockville amp

I installed this inside the dash of my Jeep Wrangler JK. It hides perfectly behind/under the glovebox. I have an aftermarket stereo (Alpine iLX-W650), and I upgraded the 1-ohm dual voice coil (DVC) subwoofer that comes with the factory Alpine “premium” sound system to a 2-ohm DVC shallow-mount sub (Pioneer TS-SW2002D2) that has much better clarity and response. This amp adds some much needed power back into the sub since I cut it in half by doubling the ohms of the voice coils. FYI: The power cable pigtail is only 14 gauge wire. Because it’s installed location was so close to the battery, I only ran 12-gauge wire to the battery. Just cut the in-line fuse off of the pigtail and splice in about 2.5’ of 12-gauge with the fuse going back on nearest the battery. Works perfectly without buying a dedicated “amp wiring kit” and having giant 4-gauge wire unnecessarily. Then I ran new, dedicated speaker wire back to the sub and ran the voice coils in series (so at 4-ohms). 200 watts @ 4-ohms in plenty to push the 8” sub. I only run it at about 60% gain for the balance that I prefer.

Wasn't as loud as I would've liked

I installed this in my sxs hooked to a boss audio stereo. Amp is small and easy to install in small spaces. Fine tuning will take time but very happy with price and product.
