  1. 2 amps in 1 5 Star Review

    Posted by on 10th Apr 2018

    Love this amp I never felt it get to hot even playing it all day! Maybe I just love crescendo products period! I'm not going to try any other I'm with the big c☆☆☆☆☆4 life mahalos plenty from Hawaii.

  2. Quality 5 Star Review

    Crazy clean sounding quality sound right here. Very easy to set , I love how bold an easy it is to read and very clean appearance.

  3. good amp terrible packaging 4 Star Review

    Posted by on 1st Jun 2017

    amp is good, running luke warm to touch, no fans that i can see from the outside without opening the amp up(I have not opened to check) not sure there is one. got the amp powering 6 pwx6's sounds great, clipping indicator helps with setting gains, the packaging on the other hand was the worst i've ever seen by any company in the last 20+ years if crescendo keeps packaging amps like this and expects to keep customers there's something wrong with them.

    TO: crescendo if the company wants pic's of the packaging email me and i'll send them

  5. Enjoying the sound quality as i write this 5 Star Review

    Posted by on 13th Apr 2016

    Have this powering 2 focal tis1.5tweeters, 2 Rockford 6.5pro mids, 2 focal access 5.25, and 2 crescendo pwx 6.5.. Hands down the best sound quality I've ever had out of any amplifier I've owned. You won't be disappointed with this amp( also, the cresendo pwx are blowing the Rockford's out far as SPL and sq)

  6. Best amp ever 5 Star Review

    Posted by on 3rd Oct 2015

    Amp is a beast its clean and clear with lots of power I have it on 6 prvs, 2 6x9, and 2 tweeters with plenty of power left over to add more mids are highs if I want to. The customer service guys are awesome they respond to emails fast and super fast shipping I'm definitely a lifetime customer and fan.

  10. CAN YOU SAY, HEADROOM!?.... 4 Star Review

    Posted by on 13th Apr 2014

    This amp is a BEAST! Not only in size,but output! Clean signal with power to spare,which adds up to lots of headroom! Only complaint is the pop I receive through the speakers when powering down the amp while using my RF Sixty.1 processor. Which is probably due to the amps slow turn-off time or mute circuit? But I hope to eliminate this with a delay relay to the processor allowing the amp time to shut down? All in all....GREAT product!! Just wish it was made in the U.S.A,,
