Let customers speak for us
from 3464 reviewsI 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

Payed big bucks for the best sound but didn’t get any stickers

ZR 10" Subwoofer 700 Watts Rms DVC 4-Ohm

These speakers made a big difference from stock I can hear the speakers on Harley over 60mph.
