As if harnessing power into the original Stealth amps wasn’t enough, Stealth Shot 500w amps take the mini amp game to the next level. Using the latest integrated circuit Class-D full range amplifier technology never before has this level of awesomeness been packed into an even smaller 3” chassis.

The line-up includes a Quad Shot 4 channel, Double Shot 2 channel, and a Single Shot monoblock. Each configuration has sufficient pre-amp crossovers for any system, accepting hi-level or low-level audio signals. For applications without a source unit, consider linking these pocket-sized shooters to the Bluetooth-enabled Stealth 4-channel.

Great for small spaces

In my 2000 Jeep Wrangler I have the challenge of not wanting to give up any precious interior space, but it's also a soft top with mud tires, so the audio demands are higher than the average vehicle. This little amp fits perfectly under the front seats up in the dash under the steering column, taking no extra space, and has very good power and sound quality for it's size. Great form factor for small cars, great value for the money. I also called Soundstream with a question and quickly got to talk with a live person who quickly addressed my question.

A real surprise

So I waited to write this. Been in my truck for a while now. Soundstream over the last few years been hit and miss. Well this little compact amplifier is a hit. My space was very limited. I installed this amp under my driver seat in a 2020 Tacoma 4 door. Have sub amp also under seat with it and no problems what so ever. It integrated into my oem wiring and runs my back doors on rear channel and my dash and front doors on the front channel. Wasn't looking for crazy loud. Just needed to complete the mids and highs with the bass from rear sub box. The amp is running replacement mtx coaxials door speakers and ds18 dash tweeters without any hiccups. Stays clear. And gets plenty loud for what it is. My Tacoma sounds like how it should have from factory. My buddy has same truck with the premium factory and mine sounds so much louder and cleaner than his. My music is way more impactful and clear. He's really upset he bought the extras and it cost him way more than what I have into mine.
