Great Sounding Amp
I love the quality of the sound that comes from this amp. I just wished I had the clipping light on this unit as it does on the RD400/4. The only reason I went with the XD400/4 over the RD400/4 is the signal to noise (dB) on the XD amp.
The XD series also comes with a 2 year warranty as opposed to a 1 year warranty on the RD series amps
Awesome little amp
Needed an amp to fit where the stock Monsoon amp was in a 4th gen f-body. This amp fit on the original amp bracket without any problem. Hooked up to two pairs of jl audio c2-650x coaxials it's the prefect amount of power.
I’m impressed. I was running 3 separate amps to power 4 pair of JL speakers in my doors and one pair in the dash. I replaced them with this amp. Much cleaner looking and sounding. My subs are stronger because I’m drawing less power. My other amps were running warm and shutting down so I like that this has a cool down mode. Easy to hook up and install. The best terminals of any amp. Just ordered one more for my dash and will drive extra tweeters off the other channel. Never hurt to flash JL too.
clean clean & clear
geese may i just inform you that this amp does not stop the sound quality it delivers is simply outstanding, thank you Sonic for making my music experience pleasurable.
Two words... Sound Quality!
I was using a JP 4 channel amplifier prior to installing this. There was this annoying whining sounds when the volume was down. I checked all my grounds and even added a ground to make sure I was good. Sound never went away. I actually tried the class D JP 4 channel and the class AB JP 4 channel amplifiers, they both had that sound. I decided to stop being cheap and get an Amplifier from a reputable company. This amp provides all the power I need to my infinity kappa component sets . Sound is clean, clear, and crisp. Also, that annoying whining sound is gone. It's crazy how quality equipment just performs cheaper equipment in areas other that power. Power is cheap these days but quality of components is not. I was a JL guy back in the 90s but gave some of the cheaper products a shot. Ill put my money of the quality stuff... JL being one of them. Hopefully this review helps someone.
