Let customers speak for us
from 3525 reviewsLove the amp does extremely well on my Harley.

Love product

The dsp is great, it works absolutely perfect, it tunes the frequencies to the “T”. Couldn’t get a better sound.

It works amazingly, one of my best purchases absolutely pushes my speakers to its max.

I love the way they sound, super loud and clear, def will get some more soon.

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🤞🤞

Ultimate compatibility with the DS18 6.5" and 8 " mid range speakers.

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.

Work tremendously great perfect at any speed on the highway, etc.

Very loud and very very clear, won’t ever buy any other brand from now on. You can hear me coming from a mile away thank you ds18 for making quality affordable products :)

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…

Works great and love using the Apple car play.

Fits perfect looks great sounds amazing crystal clear
LEDs are bright
