Let customers speak for us
from 3532 reviewsCurrently running four of these on all doors and it bangs and is way more louder and clearer than what I thought it was going to be. 10/10 definitely will return to ds18s for more stuff in the future

Very loud

The best single din I’ve ever used, love that you can use the app to tune to your liking as well as change the led colors to whatever you like. So many useful settings and would definitely fit in almost any car.

Great product and service.
Easy install and sounds great.
DS18 , could I get a few stickers to rep on the sling by chance? 🤘

The best loaded enclosure!
I bought the single loaded zxi12 and this is the best loaded box I have found to date. It is tuned nice and low, the sub has very impressive excursion to keep air moving down in the 20's. I will be selling off my other subs and exploring Ds18 brand for the foreseeable future. Excellent product! No buyers remorse here

Sound quality is top notch! Nice loud and crisp! Paired it with my skar 1000x4 and couldn't be happier! Upgraded from my pioneer 6x9s.

Love 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.
