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

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!!!

This plant is of good quality and came out excellent.

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.

Compact and powerful

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.

At first, I was skeptical because the price is so good. Kinda like that saying you get what you pay for but let me tell you the sound is amazing it’s loud great quality, extremely happy I suggested to everybody I told all my friends who ride as well definitely a lot of bank for your buck.

These amps are Brazilian amps, they were never meant to be sold in the US, my amp went out and the seller would not honor the warranty, the US sound digital would not touch it because it was not from here, the Brazilian sound digital would not fix it because it wasn't sold through them even though it's their product

works great
