I do custom audio mainly on bagger motorcycles and Soundigital is all I use for amplifiers. Never had a failure in the 6 years I've been using them.

I bought a couple of these when they were $70, I traded one today for a R250.4 that didn't end up fitting under the guy's seat. The SounDigital did great. The crossover isn't adjustable but that's ok, it sounded pretty good. The wiring was done, all I did was hook it up, set the gains with the DD-1 & send him on his was after 20 min. It was worth the trade (for both of us really). Thanks for the heads up on this

These are intended for the Brazilian market, that’s why is not showing on the US website. From what I heard, they’re the same as the EVO-X but without the active crossovers. I currently have 3 of these “gray” Soundigital amps, one 400.4 and two 800.4’s on my Harley with a DSP so, I don’t need them to have crossovers and I’m super happy with them.

i have installed a bunch of these here in brazil and i love this thing man never had a problem with them and i love the SQ . love this little thing

Nossa olha onde foi parar o famoso SD400.4 da Soundigital Brasil, deve ser um dos módulos mais vendidos da marca, produto de muita qualidade e eficiência, pois além de consumir pouca corrente ele é bem compacto e eficiente, cumpre oque promete.

In my tests it did 65wx4 at 4 ohm, 122wx2 at 2 ohm 248x2 bridged at 4 ohm at +- 14.8V, and it sounded really good on the Klipsch RP-160M

I've got one of the Stetsom Iron Line amps zip tied behind the dash of a Honda Ridgeline. It's running an Atoto A6 Android auto radio, four 6.5s, and two silk tweeters. I'm so impressed with it I bought one of these Soundigital amps for a light weight install in my 91 Camaro. Glad to see this video! I've noticed some of the artifacts these little full bridge amps add but in a noisy vehicle and with a 31 band EQ it makes almost no difference in real world use. The fact that I have about 350 bucks in EVERYTHING in this vehicle including install gear, the 6.5s, and of course some old school goodness in the form of MTX silk tweeters I installed in the dash simply blows me away. Comparing this to the setups I had in the early 2000s it really does feel like we're living in the future we dreamed of! I'll be adding a pair of Hifonics 6.5 subwoofers soon.

Pretty nice to see car Audio companies adding new technologies to their products and make it more accessible for people either withing a budget or not much space to work with

These are great! I just bought 400.2 EVO 5 for my fronts and it does the job well

These comments and reviews are great. I'm trying to throw together something cheap but with decent sound in an old dodge truck. Nothing crazy, it's a beat up 98 and I'm getting old (46) but still like my metal with a bit of a kick. Back in the 90's and 00's were my time to shine when I could be heard and felt blocks away.
I've always been impressed by small amps though. At one point years ago I had a little punch 60 with two punch 12's. Thinking that wouldn't be enough I pulled into this place called stereo would in Jacksonville North Carolina and bought a 2000w V12 Alpine along with Alpine mids and highs and had their install guy have at it. Got called when I thought they were done and he had me come back in to check it out. That little punch pushed the 12's way harder than the alpine did. Ended up just using the alpine for the mids and highs. Later on switched out the 60 for a punch 120 I think it was and it was insane. At least once a week or so I had to tighten my trunk lid bolts and anything else that could rattle loose and that was even after putting locktite on everything and dynomat.

Looks legit! The 1% test bridged was a little disappointing but it did rated uncertified… for the $$, that’s a win.

[bertastleford]

These are my favorite reviews. Small amps that do big things. They can fit in all locations and can give you some great sound. A++++ Big D

[MrDopey]

That's a kick ass little amp! Great review Big D!! I wouldn't mind getting 2 of these to run all my mids & highs in my Altima

[ryanjohnson]

They sell in USA, alot of motorcycle shops sell them, have 2, evo 800.4, running bridged, 400 watt rms. For over a year, been waiting for you to test that one. But glad the smaller one you did. I tun 5 amps in my bike, hopefully you will test the ds18, 3600.4. Rumor is 800 watt rms in channel mode. As I need 800 watt rms for my mids. Yet.

[samwiseme]

The tiny size and low price of this amp are a testament to good engineering. The sound quality 'issue' could be mitigated by restricting the frequency range the amp was asked to reproduce. In other words, I could see this amp being useful driving multiple midrange and tweeter speakers to sound levels below 'earth shattering'. Of course, that would require an external crossover. Looks like a winner!

[MrDopey]

Because I completely forgot about this one, I wound up buying 2 Taramp 800x4 TS series (2ohm)
I haven't hooked them up yet, but they're setup like you were saying, positive and neigh together when bridging.

[Tallchevy]

I have the 400.4 EVO2, bridged on my Harley powering 2 Cicada 6.5 coax horns. I also have a dsp, and the sound is so clear and loud that I can hear them at higher than highway speeds.

[dremach]

I have an old JL audio 6ch amp in my truck just because I had it laying around... amps like this make it hard to justify having that giant old thing around... lol. Wish they would have put in a fan on this thing or make the case more of a heatsink - that would have driven the price up, but it'd be worth it IMO.

[davnkes]

I bought a different brand on Amazon and it was pretty good quality. Still got a little hot but I was also impressed. Timpano 500.4 2ohm. My subs blew its fuse but I plan on running two of them for my mids and highs.
