Let customers speak for us
from 3495 reviewsThese speakers sound awesome, definitely loud. Installed 4 of these 6.5s in a 20ft boat pushing rated RMS to each.. Only wish I could wire a single color without a lighting controller like the previous hydros I had in my old boat.

I’ve bought a few if these. They work and sound great! Recommend, especially for jeep!

I had the 15 in if this sub before and these 2 10s was more bass than the 15 love thses subs

Loved it, just take your time mounting the enclosure to the tailgate. No need for drilling on the steel or rivet, tailgate have M6-1.0 thread holes that you can use to hold it. Hope this helps.

Really loud and incredibly easy to install—I'm really happy with it!

Great 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

3" High Compression Neodymium Hybrid Driver/Tweeter 140 Watts 1" Pen 4-Ohm Vc

GEN-X 4x6 2-Way Coaxial Speakers 45 Watts Rms 4-Ohm

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
