Let customers speak for us
from 3963 reviewsThese speakers are everything they describe them to be and more. They are loud and they are tough. I have tried them out. They will handle the watts. I recommend them for anyone that LIKES IT LOUD!!
First off after unboxing was very surprised at the weight of the amp Great quality Good design good build very rock solid installed in a 2022 ram rebel I already had everything ran old amplifier just disconnected and reconnected wires never touch the volume setting what a difference running for JBL 939 2 ohm speakers. I thought the speakers sounded very well before this amplifier brought even more life to these speakers very satisfied absolutely amazed at the quality of sound!! Would highly recommend this amp very satisfied thanks DS 18 family
Worked great thanks ds18 crew
I'm happy
I got these for my speakers in my Keywest boat and they fit perfect, are made of great material and are water proof.
All-Around great subwoofer
It’s such a great product, I want more of them! I build classic cars and like the look of the original radio in the dash, however I love great music …. So this easy to hide unit is perfect for me!
Great Quality, highest price of shallow mount I could find and definitely worth the price. Only thing is I would suggest getting set up in a ported box if your goal is to have the most sound they will offer . I currently have in sealed box and want more out of them. So next step is to have custom box build for these speakers under my back seats in 2017 Silverado crew cab.
Definitely will refer to other s best quality products hands down
