## Customer Reviews

### ⭐⭐⭐⭐⭐ Great system and priced right.
*by M***G on November 13, 2020*

It was easy to wire on my Road King. It sounds fantastic at speeds up to 85mph. The mounting brackets for the speakers could use a serious redesign. The stamped generic sheet metal clamps are frustrating to make fit right and tight. The wiring took 30 minutes but the speaker mounts took 2 hours. This system sounds just as loud and clear as the Boom Audio Harley sells for hundreds of dollars more. Looks suspiciously the same too...hmmm!

### ⭐⭐⭐⭐⭐ Awesome loud speakers
*by W***S on February 8, 2022*

Great product. Really like them so far, they are super load even over my after market exhaust. They look great as well pretty good quality the mounting bracket’s are kinda a pain though Overall can’t beat the price!!!!

### ⭐⭐⭐⭐ Great motorcycle speakers!
*by J***Z on October 19, 2020*

Great value for the money. These speakers seem to be really good quality. The fuse that came in this was bad so I had to replace. Bluetooth connection was easy. The only con is there is no bass. I put these on my Harley and I don’t really notice the missing bass!
