Just had my amp installed and so far so good!! Very happy with it!
Great amp, great power, puts any speaker to work
Let customers speak for us
from 3501 reviewsHello all, just had my DS18 FRP 3.5k amplifier today, Inhave it running to 2-12inch high excursion DS18ZXI subwoofers, and wow!! It slams soo hard, clean extremely powerful hard hitting deep bass, so clean, no distortion at all. It shakes my entire Nissan Sentra. I am 53 years old an O.G. In the car audio bass world. DS18 is my new go to car audio brand. Thank you DS18 for making such a great product. It will be my brand for future vehicles I am not even close to slowing down on car audio. I would have given it a 10 star if I could, thanks again DS18!

Great product!!!

Hey these things slap hard i love these nice loud clear sounds 💯 💶

These speakers are nice and loud. Clear mids and highs. Can hear at any speed.

Bought these for my 2024 Road glide to replace the factory junk and let me tell ya, these did the job. If you just want to be able to hear your stereo on your RG then these will do the trick. You will need 1/4” spacers for a perfect fit but totally worth it. These are 20hm like the OEM system too.

These 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.
