Fit perfect and just the right power. Awesome for the price
Love the amp does extremely well on my Harley.
Ultimate compatibility with the DS18 6.5" and 8 " mid range speakers.
Let customers speak for us
from 3627 reviewsOverall great sound quality and improved my sounds tremendously from a voice perspective it elevated it to a differnt level will definitely recommend to others!

Love the way it works and easy to install

Delivery was fast, and showed up on time. Very powerful amp, and so far the best amp I have ever had. Make sure you have the proper electrical system to power this monster. Haven't had any problems with it so far. Definitely will be buying 2 of the hool-x15.1 dhe
high excursion subwoofer to try them out as well

I replaced a skar 100.4 with this one and my speakers came alive, love this amp and also very small

These speakers are beautifully made and sound awesome! Very loud and clear and the LED lighting is the perfect touch.

Popped right into my factory speaker slot! Great quality gives you that organized clean look your heart desires 🤣

I have ordered a few things from DS18. I have their equipment in my motorcycle and I am enjoying it. I had an issue with one speaker that didn’t work but I was able to get online and get a replacement sent under warranty. Fast shipping.

Very simple to install and everything is self explanatory

When it's comes to quality and clean music ds18 is the way to go

Good speakers sound clean, my cousin has some on his truck, and I could hear them pretty far, it was only like at 30 %, and was nothing I'd say a 5-star review, make them a little bit louder, and they will sound good

I love them. Great build quality and sound.

I am glad I picked these for my soundbar. They don't light up but that's ok. They sound awesome!!!

Fits nicely under the front passenger seat excellent sound for the price.

Sound is crystal clear I came from a power bass 10 which the Bluetooth went out and the sound quilling of the da 18 is the same or even alittle better then the power bass.

10/10 must try again
