Amplifier (400W 4 Channels)

For the money, this is a no brainer to step up from junk internal head unit amp. Transformed my audio so much I will be ordering another for my truck. Sound is clear, install was a breeze, plenty of power, and it fit behind the dash for a simple, install. The quality of the housing and sound was better than expected especially for the low price.

I used to have a Power Acoustik 2500 watt amp for my 2020 Ford Mustang. That thing could barely take 300 watts RMS despite the rating. When it finally went out, I bought this micro amp after I saw a guy on YouTube power 4 kicker solo baric subs with it. I was like “no way this tiny thing will perform like that!” Boy was I wrong! This little guy packs one hell of a punch, especially for 60 bucks! Not to mention the sound quality is so much better than that Walmart amp I bought. I have it hooked up to two Planet Audio AC10D’s in my Mustang and I couldn’t be more impressed!

This little thing rocks. Small enough to hide anywhere in the vehicle.

Its worth every dollar , very power to be so small , love it an will buy another next week for my bike

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.

Bought two of these amps cause of the small package, price and the good reviews but man was that a bad choice. Both amps have been making a high pitch noise straight out of the box with the gains all the way down, even with the rca’s disconnected. Have checked my connections, swapped out rca’s, relocated grounds, swapped out my dsp and even put in inline filters to try to stop it. Even had a problem with the 800.4 with no sound brand new out of the box. Put some older amps in and every thing works perfect.

Omg what a difference. My only complaint is the power and remote turn on are so close they were touching and I couldn't figure out why the amp wasn't turning off when I turned my truck off. Once I figured it out I was very happy. For $60 its awesome

This amp hits for being so small. It does have a little buzz at low volume. But not when playing music. Very happy with the performance. Pushes my 6x9s that can handle 120 watts with ease, and gain is lowered so I don't burn them out.

Small compact design and delivers a lot of power

Produto bom uso bastante

Muy potente y compacto me gustó trabajando diario ya por medio año

ne vous fiez pas aux apparences car elles sont souvent trompeuses. Ampli très puissant et très fiable.

È piccolo ma potente sono felice per il mio acquisto
