Don’t waste your money
Purchased to use on a motorcycle, worked great for about a month. Now it won’t drive the speakers. Checked connections and power, power led comes on but almost nothing out of the amp. I had it tuned pretty good, gain knobs we’re only about 1/3 from bottom, now 100% and still nothing. Should have stuck with a hood name brand from the beginning. Chinese made garbage.

Not what I thought it was supposed to be.
Says 10,000 watts. This thing is like 8” x 4”x1.5”. Looks tiny tiny. We shall see what it’s all about. Not to confident though.

Good compact amp
Good space saving amp. Installation was pretty strait forward. The power wires could be bigger. Would be nice if it only had terminal blocks instead of a pre wired harness but...all in all a good amp for my Polaris side by side.

First and foremost, this fits PERFECT with room! Paired this with my Sony AX7000 stereo(Harley touch screen radio is outdated). Easy to use and compact. This runs my 6.5 Kickers Lower fairing and 6x9 kicker saddle bag lids. Recommend!

What a mixed bag of reviews for an item from a reputable company. I guess you never know how someone wires up an amp or how they run it. I use to buy soundstream back in the early 2000's and never had a single issue with them. Bought this to replace my old HOGTUNES amp on my 09 Harley Davidson Ultra Classic. 4 6ohm speakers (hogtunes) wired in parallel to the front channels (3ohms). Used the High Level Inputs and removed the additional ground wire from the inputs because it was giving electrical feedback. All in all great little amp. Much higher and crisper sound...will definitely need to swap out the speakers soon as I'm sure they'll be put to work from the amp. At this price, and this size, it's really hard to beat.
