SounDigital - Car Full Range Amplifier 800 - 4 Channels 800 Watts RMS 4 Ohm - Compact Size - Professional Quality - 2025 Best Performance Award

Compact and powerful

I ordered this Soundigital 800.4 EVO, the big brother to the Soundigital 400.1 EVO I bought for the front speakers. Same powerful output X2 as its little brother!! I am running these two amps in my 2020 Harley-Davidson Road Glide. Bridged both amps, the 400.4 running the front two 6.5” and the 800.4 running the two rear 6x9’s. WOW!!! Pair these amps with a good set of Polk marine speakers and a small EQ or head unit with a good EQ to dial it all in and I’d put this setup against any much more expensive setup any day!!! I do concert sound for a living and understand sound delivery and this system sounds AMAZING sitting in place or running 75 mph down the road… For the money, it just cannot be beat!!!

I dynoed this little monster and got 241 watts out of every channel it sounds clean and it's so small it fit under the head unit on my 2022 HD road glide limited I definitely recommend this amplifier as it is a true 800 watts not like so many other companies that constantly lie about the power numbers.

Yes it’s not the U.S. version but if you want a good amp for a great price this will definitely put power to your speakers. Only had for a week at the time of this review but 5 continuous hours of playing at 5 hours and it did its job. Will update after the riding season and playing it at full tilt.

These little amps are truly powerhouses for the size! Super compact and really powerful! I have installed 1 so far and it blew my expectations out of the water. I would have rated this a 5 star but when I ordered 2 of these I was only shipped 1. It was a bit of back and forth with the seller but I did get my second amp shipped to me. This amp also fluctuates in price quite a bit so keep an eye on that. I got mine for $134.00 each. I've seen this amp go from $119.99 - 189.00 here on amazon.

Was leary about this as I've seen some from the same brand for 3 times as much.i was replacing an amp that was twice the size of this and it did not disappoint. Half the size, and less money than the other and just as powerful.

Bought 2 of these amps back on March 7th but didn't install them until recently duel to my bike having work done on it. They didn't last a week before they stopped working. Just quit on me with no warning. Now my return window is closed and I'm stuck with 2 blown amps and out of $300+. Don't waste your time or money. Very disappointing 😞!

works great
