Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.

- Reviewed in the United States on January 14, 2025Installed this in the fairing of my 2017 Road Glide. I paired the amp with some JBL speakers. The system sounds great, no static issues, and was easy to tune. I can easily hear my music doing 80 down the freeway! It has been installed for 1 year at this point, with no issues.

- Reviewed in the United States on December 15, 2023Don’t waste your time or money unit doesn’t sound great. I was trying to save money so I decided to put up with its less than perfect sound. After 2 months it just died and constantly blows the onboard fuses. In my younger days I was an MECP tech so I assure you it’s not me. Spend the money on a better unit as I am now.
- Reviewed in the United States on August 12, 2024I bought the amp paired with the Sony AX7000 easy and sounds great.
- Reviewed in the United States on April 22, 2024I am amazed how clear and powerful this little amp is. I was worried about quality with the price, but damn this thing is absolutely rocking the 4 6.5's on my 2018 street glide with the gains under half way up. I would highly recommend this amp to anybody with limited space looking for best bang for your buck. Amp is crystal clear and has plenty of power to spare for 4 - 4 ohm 6.5" speakers!
- Reviewed in the United States on January 14, 2025Works great and easy to fit under the faring of my Harley
- Reviewed in the United States on October 13, 2022Installed it in my truck a couple years ago, powering 4 x Kicker CSC68's and worked flawlessly for 2 years...now each time I start my truck the speakers won't come on for 2-5 minutes, and then cut in and out for a few minutes, then it works normally. If I turn off my truck, then turn it right back on, starts doing it again. Buying a second one now since there's virtually no significant warranty period and so I don't have to re-do the install. Hope the next one lasts longer.
