Amplifier SounDigital SD 400.4 EVOX 4 Channel 400 Watt rms EXTREMELY reduced size Class D Full Range

Don’t be underwhelmed by the size, technology is improving daily and these have come a long way. Built a sound system for my wife and both the sub and 4 channel fit behind the headunit.

Sounds amazing and has alot of power in tiny footprint.

Ordered the sound digital amp for a build that didn’t happen for a couple months. Like others have already reviewed, amp is a factory defect. Right out of the box the Amp channels 3+4 clip even with gain turned down. Seller wants me to send it back to manufacturer which will take more time. Save yourself the hassle and buy from someone like nvs audio that stands behind their product

Very good

I purchased this product in the middle of building my HD. When it arrived it was not in a box for protection, only a plastic bag (which I wrote a review about. We finally completed the build with the music being the last step and the Amp is not responding to level adjustment. I have photos time stamped with last weekend date on them for verification of installation date. The site will not let me return for an upgrade being the date has exceeded the limit, is there anyway to have this corrected.
