Great amp

This amp is great and is being used to power pro-sm69 and two horn tweeters in my victory kingpin. It’s more than doing its job…Great Amp! Great job guys

Great power supply paired with 4 speakers

Motorcycle speakers

6.5” didn’t fit the best in Harley fairing but I made it work. 10/10 recommend. Loudest speakers I’ve ever heard.

Great Amp…more than enough power!

This amp was recommended by Aaron at DS18 and is being used to power my Extremely Loud Soundbar loaded with two 8s & two horn tweeters in my Gladiator; it’s more than doing it’s job…Great Amp!

Pair of PRO-X8.4BM and a Pair Of PRO-TW1X/BK Package

Sceptical but satisfied

So far so good I'm pretty happy with the sound and quality of your speakers ...gotta say that I reluctant to buy them because of the fairly cheap cost but am more than satisfied. Let's see how they hold up🤞🤞

X 4-Channel Ultra Compact Class D Amplifier 4 x 120 Watts Rms @ 4-ohm

A BEAST

Stock head unit flashed to another amp brand high input capacity or low-level input delivering high RMS powering 4 speakers via 2 channels is just nice. It has 4 channels though. So plenty of capacity left. The size of this ION? Perfect! May fit side by side inside fairing. Did not try it but almost canned my other amp to buy another one if these to run my other 2 speakers and tweeters.

6.5" Mid-Range Loudspeaker with Dual RGB LED For Cone & Dust Cap 250 Watts 4-Ohm

Powerful Subs-well made

Installed these in my Harley bags with Nagys 10” rings-make sure to get the mega rings as regular ones won’t fit these. These subs are built extremely well and extremely powerful to be a shallow mount. They beat. Make sure everything is tight lol…
