Compact and Powerful: Soundstream ST4.10000D 4-Channel Car Amplifier - 90WX4 Review

Not bad for the price. I use it for a truck with a small cab. I use two tweeters, two 5x7 coax and one 8 inch DVC subwoofer. Very clean sound for size and price. Very, very good offer. Very small for 1000w, most likely not at 1000w but still very good for $99.00 Easy to install, the wiring harnesses that come with the unit are fine and can easily break if not careful.

Nice little booster, likes to turn on the protection when it's fun. If you have a highly sensitive speaker this amp is great as you can realistically drive it up to 50-60 watts RMS at full speed with no heat or protection. Put this amp on some starved 6x9s or components and you're in for trouble. distorted sound from the speakers is protected.

I just installed an amp on my bike replacing a 2 channel Kenwood. It is very important. I read reviews that there were some clicks when playing music out loud. As soon as I tuned it in, I turned on the music and listened to pops as well. However, I did not connect the ground to the speaker level inputs. Once connected, oh boy what's the difference. The music is crisp and has that mid-bass all the way to the top and bottom panels, with the music midway through. I will ride it for a while and…

Dude I really didn't know what to expect from this amp considering its competitors are much more expensive but I really like this little amp. I installed it on my 2018 street slide and it rocks. It was very easy to install and performs quite well and is my personal favourite, it works really cool which guarantees me a long lifespan. So unless you want to pay $400-$500 for a rocker or hog tuning system, I really recommend this amp. I've used Pioneer 4-way speakers in my covers and fairings and…

A very powerful amplifier with a very small footprint. Installed this small 4 channel amp in my '98 Jeep TJ, since space was limited I had to find a small amp with 4 channel outputs and a stable 2 ohm impedance. This amp fitted perfectly, I built a small platform to mount to a standard jack under the passenger seat (there is a hi-lift so stock jack is not required), vented the platform and placed the amp 3/ 4" keep it as cool as much as possible. The amp worked even better than I expected…

Used this for a Kenwood aftermarket upgrade in my 2005 Jeep Wrangler Rubicon. Worked great! There's almost no room for anything in the Jeep TJ, so this compact amp was perfect. If you're wondering (like me) if/where to install this... *I was able to install it under the steering column. The speaker still has full up/down adjustment.* This arrangement protects it from direct water/splash as I drive the Jeep quite often (and tend to get stuck in the rain - thanks to the weatherman... )* Next to…
