Let customers speak for us
from 3793 reviewsWow these sound great. Running in my boat that also has JL Audio 8.8 . The DS18s sound better and takes less power to run! Highly recommend!!!

Put 4 pods and loudspeakers on my Ryker 900 and couldn't be more happier. Had to mod just a tiny bit but worth it. Great price and the quality and sound is GREAT!! Thinking of changing 2 of the loudspeakers to midrange the and see how that sounds.
Performs great amazing sound

Best subwoofers in the market and business ds18 I highly recommend them

Got a pair of EXL-XX12.2DHE‘s bumping hard on a 5k amp with 2 chucheros on another 5k amp and 2 more 1k amps powering my tweeters and drivers. No flickering or dimming of the lights on even the heaviest of bass on full volume with only 1 of these batteries. Love this battery and love their subs!!!

Worked great had a problem with the first pair order talked to them .the help was very good I got new ones in a couples days

Great

Great sound

Powers my 6 ds18 mids with ease and can hear me from half a mile away clear

SXE Class D 4-Channel Full-Range Car Amplifier 4 x 275 RMS @4 Ohm 4000 Watts

I bought the old Gen X 5x7 in 2022 and they were great lasted me 3 years! I bought these after my old ones gave out and since the old ones are discontinued. So far these are great! I love them on my 2004 Ford F-150

I have two of these in a 6th order c-pillar wall. And boy do they play from 18Hz all they way to 60Hz range no problem. And yes. You can feel them and hear them. 🤙🏾

Its a great player once you figure it out. Do your homework pay special attention of the wiring for what each wire does. Installation instructions are very vague. If have back up cameras the are analog you have to go into head unit menu and change the setting. Which requires a digit pin. There is a YouTube video instruction on how to do it. There is alot to this unit can do. Instruction manual isnt user friendly. It assumes that you just know what each wire does. But once I figured out how to get things working. I love it. I recommend this unit, but do wish the instructions were more specific on what each wore does.

Works perfectly with my skar evls and it hits like crazy. Love the clipping light on the bass knob as well.
