Soundstream ST4.10000D Compact 4-Channel Car Amplifier 90WX4 - ST4.1000D

Worked perfectly with 4 6x9 speakers and my JVS headunit, sounded amazing after tuning the settings. Do your research on speakers, amps and radios to ensure you get the proper power inputs/outputs. You can’t just slap any radio with any speaker and any amp and expect awesome sound. Plus you have to tune your amp for your setup and preferences. Small unit here, easy to tune, great price, looks decent. Worth the money and I’d buy again.

Used this to upgrade the aftermarket Kenwood in my 2005 Jeep Wrangler Rubicon. Worked great! Jeep TJs have next-to-no room for much of anything, so this compact amp was just the ticket. If you’re wondering (like I was) if/where to mount this… * I was able to mount it underneath the steering column. Column still has full up/down adjustment. * That location keeps it away from direct water/spray as I wheel the Jeep quite a bit (and tend to get rained on- thanks weather forecasters…) * There’s an unused firewall plug right near the clutch pedal where you can run a 4ga wire through from the amp to the battery. The cheap Kenwood head unit the PO installed has a garbage alleged 15Wpc amplifier in it that sounded terrible. BUT it has very decent DSP controls for the line level outputs. I chose this amp because I was looking for an inexpensive, super-compact, 4CH amp and this fit the bill. I saw there was also a Bluetooth version but that was more trouble than it was worth as the head unit already does that job. YMMV, but I highly recommend for my Jeep application.

Absolutely love this little thing. It’s so amazing how small and yet how much power come it. I’ve installed and have been using for a few months now and haven’t had any issues what so ever. I would most definitively recommend. One down note. When wiring to the stock stereo did have to lengthen the precut wires quite a bit to ensure they can be connected correctly. I just wish the speaker/power was a bit longer to cut to length instead of having to lengthen so otherwise great product and amazing preformance.

Man I actually didn't know what to expect from this amp considering that its competitors are priced far more expensive, but I actually love this little amp. I installed it on my 2018 street glide and it rocks. It was very easy to install and it cranks out quite a bit of power, and my personal favorite it runs very cool which insure me that it will prolly have a long life. So if you guys don't want to pay the 400 and 500 dollars for rokker or hog tunes system I really recommend this amp. I used pioneer 4 way speakers in my lids and fairing and this setup is crystal clear and cranks out the volume......I love it and give it 5 stars all the way......😁

This thing is junk, claims 90w rms @ 4 ohms. My alpine power pack claims 45w rms @ 4 ohms and blows this piece of crap away. After about 15 minutes of listening to the stereo I've lost all power, no fuses blown, connections are good, go figure. I would not recommend this thing even to someone on a real tight budget. Hold out, get $30 more and get the alpine unit.

I found this amp to be very useful for interior speakers in your vehicle. I mounted it right below my radio in my center console because it is so small it doesn't require a huge power wire it doesn't require a remote wire if you use the high-level input. Doesn't seem to get hot or anything like that Has served me well and I would definitely buy another one

I purchased this amp to build a homemade, portable, battery operated boombox. I've never done anything like this before and I did a lot of research and for the price I took a gamble on the Soundstream Stealth. I have two higher end Pioneer 6 1/2 inch car speakers and a pioneer shallow mount 10 inch subwoofer bridged all built-in to this one boombox(each speaker has its own chamber of course). The stealth has more power than I could've ever imagined! The bass is unbelievable!! I tested full volume on full gain and it stays clear and extremely loud!! I still don't understand how they got so much power in such a small unit but since it works really well I'm not gonna ask any questions. Also if my memory serves me correct the Clarion and the Kenwood small amps were not bridgeable. I highly recommend this product especially for the price.

Pretty good little amp, loves to drop into protect when the going get fun. If you have a high sensitivity speaker this amp is wonderful as realistically you can push it to about 50-60 watts RMS at full tilt without heat or protection. Put this amp on some power hungry 6x9s or components and your going to have a bad time. These were my only choice based on room and although they do get the speaker going, once I hit a certain volume which is long before I start to get distorted sound from the speakers it goes into protect.

Beaucoup plus puissant que je croyais pour le prix ça vaut vraiment la peine je pouvais seulement avoir des speakers 4 pouces j’ai installé des Pyle plg4.2 70watts rms 90/20khz Ça sonne vraiment bien Pour du 4 pouces👍👍👍Ah oui j’ai dû Baisser l’amplificateur de moitié et c’est toujours très puissant sinon mais haut-parleurs aurait lâché

did not work. huge distortion. comfusion wiring harness. buzzing through soeakers and almost blew my speakers. garbage quality returned immediately

Easy to install works great on motorcycle
