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

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......😁

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

Good amp in that it has clear sound and definitely adds power to under powered speakers. It just lacks the bass output. for my liking. Added a powered bass afterwards.

Installed in my car to run interior speakers (new Kicker speakers and speaker wire installed -90w RMS in the front and 75w in the rear). It puts out plenty of power to run these speakers at any volume I will ever need and I notice very little noise/distortion at higher volumes. The amp that I got for my sub was a fairly large footprint so the very compact size of this let me pair them on the same seat back so I didn't have to give up any more space in the back. It looks nice, takes up very little space, and it does the job well.

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.

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

Very powerful for such a small unit. If you own a Harley this will fit on top of the Radio head unit. running four speakers 4ohm 100w . With this combination I have to turn the gain down to 25% of its capability to keep from over powering the system. Down to the performance of the amp and speakers. I can listen to the radio at 75-80 mph clear as day. I will purchase this amp again for my boat.

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
