I have this powering a 3-way component set of MB Quart up front and a pair of DS18 two-way components in back and it sounds so good. I have went through like five or six four channel amps and was never satisfied and ended up selling them and I think I finally found the one I like the most. Because if I go to add more speakers I can also drop it down to 2 ohms and put 240 out of each channel and I'm sure that's underrated. I would definitely recommend.
Top quality amp, plays clear and loud. I have it on 4 Crescendo Audio UN 6.5" mids and 4 Crescendo Audio Neo tweeters and they sound awesome and clear. I put 2 way passive crossovers on all 4 sets. It has enough power to double my setup on this same amp.
Competition amplifier. True clean power! Beautiful amp. FAST shipping. Awesome customer service.
Absolutely love this amp. Pushes my Deaf Bounce Neo 6 1/2 door Speakers to the limit,but sound extremely loud and clean doing it
Very Happy with Amp.Clean and Clear with no distortion.Very Fast Shipping.The Best !If Your Looking For A Nice Amp,This Is The One!Crescendo All The Way!!Thank JP!You and Your Crew Are The Best!!
Nice and clean 4channel. Really impressed. Nice improvement over my soundigital 800.4
This replaced my hifonics 4 channel to run my highs, and let me tell you what a night and day difference! cant believe how well the same speakers sound with simply a better amp. Much "cleaner" sound.
An amazing amp to be so small
Awesome amplifier. I was worried about class d quality but running my 4 PWX 6.5s, it sounds significantly better than my SAE 50.4.
Got this in literally a day and a half and I live in Minnesota. When i first installed this amp, the gain was all the way down and my radio was at the volume I like to have it set at and it was already loud AF! I turned it up about an eithgh of the way and damn is it loud. You dont even need good electrical with this thing, it does rated at 13.8 volts. Thank you!
