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

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

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......😁

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.

Not bad at all for the price. I am using it for a truck with a small cab. I am running two tweeters, two coaxial 5x7's and one DVC 8" subwoofer. Very clean sounding for the size and price. Very, Very good deal. Very small for 1000w, most likely not peaking at 1000w. I kind of doubt the 1000w rating, but still very nice for $99.00. Easy to install, the plug harnesses that came with the unit are just ok, and could break easily if not careful.

Bought 2,hooked both up,they made my speakers “pop” hard every time I turned them on,they didn’t seem to do rated power,barely any difference from my aftermarket headunit.I hooked everything up right (been doing this for years and they were for my mids and highs,I have a 3500 watt amp on the subs,high output alternator,big 3 + the extra wire done,xs power d3400 battery and all 1/0 wire ran), so it wasn’t a user hook up error..I did like the size,but that’s it..sent them back and bought a jp84 from his website and saved like $40

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.

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.

I am an old school audio guy who has been out of the loop for a long time. Soundstream USED to be top of the line back in the day. I was looking for 2 things: 1) Decent sound quality for my mids and highs. 2) compact size. This amp amplifies EVERYTHING IN YOUR ELECTRICAL SYSTEM! Everything electrical/electronic that I turn on created a new buzz or humm. Oh, not to mention the alternator buzz too! I moved my ground 3 times, and changed my battery terminals. Tested my alternator, re-routed my power and ground wires away from my speaker inputs and outputs, and checked my ground strap under the hood. And yes I did hook up the one ground to the chassis of my head unit as the instructions directed. Talked to my local car audio professional and he said it was the amplifier. Changed the amplifier and like magic ZERO NOISE!!! Also, this amp does NOT even come close to the advertised RMS power. If you want a super clean amp? For a little more money get the Kenwood excelon X302-4!! You will NOT regret it!!
