amp is powering my 4 500 watt nemesis 8’s definitely banging, amp doesn’t get hot, haven’t had any problems at all, impressed by this amp, not battery hungry at all
F)Pro-8” coaxial R)Pro-x 6.5
(4)1.92” done tweeters
Powered by ZXI 6 channel amp
(4) ZXI 8” subwoofers
ZXI mono amp
Installed in a 2023 gmc Sierra (Harley Davidson edition)
This system is ridiculously loud
10x louder then stick Bose system
And extremely clear
Best comparison would be it feels like when you’re at a concert/club and you’re standing next to the dj booth
Loud an clear
Let customers speak for us
from 3463 reviewsI 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.

Really really loud and crisp and clear. Can’t complain, I paired these with my amp/dsp and it’s great. Will be buying more products.
