Very very happy with my purchase, easy to use, very compact, sounds great for its size.. I wanted something nice and simple that worked but was not looking to break the bank and was limited on space, this little amp was more than perfect for me, only downside is that it gets really hot and that was just during testing, I mounted it in an easy access place and it’s not enclosed.

Small and compact enough to mount in small a small area and provides plenty of extra power to the speakers to give me the extra power i wanted. Instructions were clear and easy to understand. I mounted the unit under the center console, and ran all the wires where you cannot see them, wanted to keep a factory look.

Great MID-level motorcycle amp. Just make sure to pair it with matching speakers for the best results. Love the bass HP LP filters with full adjustment. 4ch or 2x1ch sub. LOVE IT!

Easy install, small footprint and clip-free operation so far. Does exactly what it's supposed to, imo. I matched it with 4 kicker dsc680's and it jams pretty good in my f350 cc.

Bought this item on Best buys open box rack and thought I was getting a good deal come to find out the same day I looked and it was $20 cheaper online even $20 cheaper at retail stores the product was obviously returned because mounting hardware was missing and one of the knobs for volume was broken. I Ended up having to go to Nashville on business and by the time I returned I just didn't want to deal with it

So far so good with this amp. It has a nice small footprint so it fit nicely in the cabin of my boat so it can’t get wet. Has nice output for the mid level Kenwood marine speakers I’ve paired it with and the set up was ok given the price. The main issue is this amp puts out a lot of heat given the low output so be careful where you mount it and it also doesn’t have the newer bells and whistles a lot of higher price amp have to set things like gain, but that’s obviously to be expected. Overall a good deal.

I got this amp because my Sony XAV-AX3000 head unit only produces 20w RMS and 55w peak (and it hardly ever hits it’s peak, but then again head units can only provide so much juice). All in all, i am very happy with the performance of this little compact beast. Was quite easy to install and get up and running in less than an hour (didn’t have to run power from the battery since my car has a 20a fuse for the audio, so that saved me from a lot of unwanted work).
I have 4 kicker 46CSC654 speakers rated at 100w RMS and 300w peak and now paired with this little amp (which now sits in my glove box), they really sound crisp and clear. This amp only provides half the required RMS power to drive the kickers, but they sound considerably better than when connected to the head unit.
One thing to note though is that this little bad boy heats up quite a bit. Lets just say after turning on the car and listening to music for 5 minutes, this unit gets so hot i could not keep my hand on top of it for longer than 5 seconds. Didn’t really expect that much heat from a little amp, especially one that has Class D circuitry. This is the main reason why i docked one star and may possibly return it. If it starts overheating and shuts down though, i will be definitely returning it - but lets hope it doesn’t.
Would really recommend this unit to anyone that doesn’t have enough room in their car to mount an amp. This unit easily fits behind the dash or in the glove box with the only caveat being its heat output.

Works great for my 8" sub that is mounted on the back shelf of my car. Since its not in a box this provides enough power. Was also small enough to hide under my radio in the dash. Super easy to install.

This amp replaced another one I had for 30 years. Very reasonably priced and I’ve had no problems with the sound quality or power. It’s very compact and fits under the seat of my truck with no problems.

I've been using this compact amp in my Can Am for about a year. Still works.
I actually have two of them. One powers the large marine full range speakers and the other powers a 8" dual voicecoil subwoofer and seems to be just enough.
Moth amps have the 4 channels bridged into 2 channels.
Of course in the Can Am (or any side by side vehicle) you have limited charging power and the Class D efficiency helps. Haven't had any charging issues with my stock Can Am charging system.

Was not expecting that much of power in a little box. This thing really packs a punch. Like the old saying goes..... Good things come in small packages. Definitely would recommend this to anyone !
