This amp is really making my 6 1/2†door speakers x 4 scream much louder than the Boss 400 that I had before on them and it’s honestly a very noticeable difference and wow great value very small and a quality amp for $60

When I first received the amp I was a little skeptical because of the size and my experience with cheaper amps in the past. Not only did the little amp meet my expectations it blew them out of the water. I added this amp on top of my budget sound system in my 08 VW. For the money and the size this amp is worth every penny.

It was easy to install and I liked the size of it. Fit perfectly on my Harley Davidson. Good quality for the price.

Worked great for a month then all of a sudden 1 by 1 each channel just stopped working. It now produces no spund and its just past the 30 day return window

My two issues with this are:1. It picks up electromagnetic interference like crazy. Gains have to be dialed down quite a bit to not hear it through the speakers. I'm at maybe 1/5 of total available potential on the gain knobs. And it's not just amp noise floor, it's actual EMI that it's picking up from the car. It changes depending on if the HV is heavily engaged and if the gas engine is running or if I'm braking (regen).2. Gain knobs are way too sensitive. It's hard to really dial in a number. I'd rather have half the gain potential that I do right now and instead get a more precise ability to dial in gains. Honestly these potentiometers need to be the kind that have detents (the clicks for fixed positions). That'd simplify things. Gain matching to my other amp and between the two bridged channels on this amp is annoying with this as it is.I'm using a KEYLOC so I can adjust my output gains up a bit more to compensate. Luckily the KEYLOC doesn't pick up EMI from the engine/wheel motors/high voltage system.Does it otherwise seem to push clear audio? Yup. It's really small too, I like that since I just needed it to handle rear fill.

Sound quality is OK. For its size and price it's pretty good.

It seems to be good build quality and it has a year warranty but when I hooked my unit up I could not get any sound. I contacted tech support and they verified that my install was correct and got me to contact their warranty department. Waiting to see if they are going to send me a new unit or if I will have to return mine to be fixed.Update: they wanted me to send in my amp for repair which I ended up having to pay the $30 shipping fee for. Now my unit is in the USA and they informed me that they do not ship to Canada. They sent it to one of their distributors to ship to me and that was 4 months ago and I still have not received my amp back. I am $70 plus $30 for shipping into an amp that showed up defective and now I don’t even have it as a paper weight.
