Hide It In Your Jeep Dash!
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.

Awesome little Amp
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.

great little sub amp
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.

Great compact amps
These compact MB Quart amps are fantastic. I’ve been in the car audio industry for over 20 years and these small amps are fantastic in my opinion. You won’t win any sound competitions but for the size and the price these are hard to beat. I have this amp and the 320.4 four channel version in a Polaris RZR and the same amp set up in my 24 foot run about boat as well and am very pleased in both applications.

Perfect
I used this with my Rockford Fosgate stage 2 kit when I added a sub to Can Am X3. Works great with the Rockford Fosgate sub.

Underpowered and Keeps blowing out
Had this connected to a modest 200w 10" shallow subwoofer. Within a few months it blew out, covered under warranty, another 5 months later it blew out again... the on board fuse pops and then it never works again. The 2nd sign that this is a junk amp is the size of the power wire is 14 gauge and the speaker wire is a complete joke. I replaced with a 300w clarion which is better in every way.

Great price, small package, big sound
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.
