Default Title
Perfect amp for the 4 speaker set up
For Harley . I also purchased the plug and play harness when I got the Amp , easy install . Only item
I didn’t get was the rear speaker backbone harness and ideas able to get it from Amazon . As with all the DS18’items I’ve received the quality is excellent , have a Jeep with all DS18 equipment.
This amp fits behind the fairing on my harley. Speakers sound so much better
Installs easily behind the fairing. Runs surprisingly cool and puts the 150 rms power to my DS18 speakers with little to no distortion. A great powerful clean amp.
This thing fit perfect on top of the radio on a 13 ultra powering a set of 6.5 ds 18s and super tweeters in the upper fairing and a set of 6.5s in the lowers and it makes all of my speakers kick sounds awesome
Installed this amp on my 2022 street glide. With 2 Pro-ZT69 and 4 Pro-ZT6 and let me tell you. Sound way better then all does over price kits on the market.
Let customers speak for us
from 3471 reviewsBought these to install in my 24 road glide after the update Harley just did they sound amazing but I did need to purchase some spacers so the fits properly

Really good power and 0 dimming on lights since installation and the battery itself looks amazing. I like that it can be laid on its side if needed.

DS18 BB5.6UF/100V-10PK 5.6uF 100V Non-Polarized Bass Blocking Capacitor

I needed to upgrade one of my amps to have more rms to the new set of door speakers I am running. There powering ds18 neo series. And the way I needed it mounted under the seat there was no way a normal amp would fit. For a small foot print pumping out over 200 rms in a reasonable price this met the needs. Haven't had to worry about clipping with this amp like the other one from another vendor.

I love the Infinite INFINITE 35 AH battery installed it on my 2013 Can Am Maverick 1000r and it has enough cracking power to start it every time see how it does when i add accessories

I love how there loud and everything but I had one go out on me

5 STAR!!! Installed these speakers in my 2019 Road Glide and I could not be happier with the clear sound!

Loud asf crystal clear

Really nice kit, AMP is also very solid and compact, fits nicely under the seat on the low profile AMP rack I bought !
Would recommend taking to a shop for installation. I’ve got a 2025 Jeep Gladiator and my only complaint is how difficult it is to disassemble the dash.
Also note this is not exactly plug and play if you intend on Amplifying tweeters and Dash speakers. These are extremely Loud and clear on Vocals.
If you plan on doing The Sound bar too, you have two RCA’s labeled FR & FL. You need a RCA Y splitter, DS18 Makes them. You actually need 2 red and 2 black splitters. Would highly recommend the speakers if you’re looking to Wind Proof the audio.

Never had subs this small but was suggested to try it and happy I did! I had 2 12s in my gladiator and wasn’t to happy with it and tried 4 of these and the sound is night and day difference! I have them in a ds18 ported box on a FR 3.5k

Have not installed them yet but the quality looks Superior

Good

Nice quality nice sound
