Sounds great but done with with audio
DS18 ZR8.4D 8" Car Subwoofer with 900 Watts 4-Ohm DVC
Let customers speak for us
from 3489 reviewsGreat product, amp can put out some good power , im running 2 - 6.5 in the front and 2- 8s in the back , plenty of sounds 👌👌👌
I usethese for my 6.5" JBL Marine speakers I added to my camper on the outside. I keep these covers on going down the road and during storage. So far thr first set has been on there 3 years and still going strong. I just got another set to have in the camper in case one happens to blow off.

The screen is really nice and easy to read. I like having a knob for volume. Use single folders for music, and the usb is the loudest input. The remote is nice, and DVDs can be controlled by the screen. Be better- the aux sounds terrible, and the BT audio is low. Screws included. Can’t be beat for the price.

They are amazing my buddy has four and they are super loud and clear love to put them in my vehicle just waiting on spacers

Good stuff

We love DS18!!!! Hits hard and is definitely loud

Very clear and loud. These went on a 2021 Tacoma replacing the factory jbl tweeters

Awesome amp , awesome control , looks amazing

Speakers were fine. Sounds great. Shipping with USPS was awful. The package was lost for over a week, and then finally found after I filed a complaint. Don’t guess that DS18 could do anything about that, but it definitely can’t be allowed to become a problem that’s ongoing. Y’all may have to consider alternate ways to ship. Again, very pleased with your product—exactly what my son wanted.

I Have it running to my epicenter from my amp, sounds great!

Comes with everything in picture and very good quality!!

Easy install with the 12in u connect with aftermarket harness adapter. Speakers are clear and very loud. Very happy

Very crispy and clear sound! The tweeters sound great just an over all phenomenal product!
