SounDigital Amplifier (400W 4 Channels)

In the UK, there's nothing close to it for under £200! It has 4 channels of 132W RMS at 4 ohms, or 4 channels of 200W RMS at 2 ohms, or two bridged channels of 400W RMS at 4 ohms. Class D premium 40A fuse Premium amplifier from Brazil and very popular in the USA.

Melhor custo beneficio do mercado, inicialmente parece que não vai dar conta pelo tamanho 80% menor que um analógico, porem a qualidade de construção é tão boa que chega a ser melhor que os melhores analógicos.

Produto bom uso bastante

Better than that

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!!!

9-17-25 I give this very tiny lil amp 5 stars so far!! I actually am using it passed thru my Fosgate RX500D amp....It is clean no humming no no hissing in the 2 RF P3 speakers I have in my back dash. I totally played myself by purchasing the Boss CE102 to drive the P3s which was an absolute disaster...that amp is so terrible it pushed interference thru my P3s and my 12" Kicker sub...I thought it was my grounds, RCAs, etc until I started process of elimination. SD EVO is clean and crisp and very small so concealing it is very easy...my only gripe is the speaker terminals are right next to the power terminals but they obviously did some expert engineering...again the lil thing sounds clean.
