The seller deserves 10/5 stars. Extremely helpful and responded quickly when I had an issue with the amp. I’m very pleased with my my purchase and would buy from this seller again. The amp deserves 4/5. Just a heads up: the orange wire is the remote. I found that out the hard way. Other than that, it’s a good amp and makes good power. I’m running 4 Kicker tower speakers and it powers them with no problem. I love that it’s Bluetooth as well.Finally, don’t forget to use OFC wire.

Fricken phenomenal! Don’t even hesitate to buy one of these. My ears still hurt. Using with 4 Polk Audio MM1 Series MM692 - 6x9" Three Way Speakers with Ultra-Marine Certification in my boat. Wow. Basic. Clean. Perfect. Don’t know if I will even need a subwoofer. Love it!

So far this is great!
The head unit died in my 21' Regal bow rider. While looking for replacement options I came across this amp and read as much as I could about it. Since all I do is stream music from my phone via Bluetooth anyway I talked myself into the fact that with this there would be no need for a head unit and I would get more power than any available head unit could provide. When I received the Amp I was thinking, wow, this thing is tiny, and I had doubts about what it would do. I am running two Kenwood 8" marine speakers in the back and two JL Audio 6 1/2 in the front. All I can say is WOW. This thing far exceeded my expectations. I was hoping I would have a volume clear and loud enough to hear the radio while running across the lake. Not only is that not an issue but I think I could hold a dance ... The head unit died in my 21' Regal bow rider.

Not only is that not an issue but I think I could hold a dance party on the island this year. My wife asked if I added a subwoofer when she heard it. The speakers are all loud and clear at all volume levels. I have only had this installed for about a week so I can't speak to how it is going to hold up long term but so far it has far exceeded my expectations.

Great small amp
I'm using this with two 8" 600w wake tower speakers on my atv. Very good power to hear clearly when riding. Also compact enough to never know it's there. Bluetooth works good through my phone music app.

Bluetooth doesn't work
I was excited to hook it up as soon as it came in. The first time the bluetooth stayed on for about a minute. Then I had to disconnect the whole system for 5 minutes. Then it connected for 20 seconds then lost bluetooth. The only way I can get it to come back on is unplug it for 5 minutes. Then I get 20 more seconds of bluetooth and poof.....gone again.

Small amp with big power.
This amp is badass! I have 4 Polk 6x9s and this amp pushes them perfect. Doesn't even get hot. Only down side was the wiring diagram which made no sense other than that this amp by far is Great!!! Keep in mind this set up is put in my Harley bags and the music is Loud and Clear. My friends are ordering theres after hearing my bike. Satisfied customer.
