Not bad for a budget amp, don't expect big things, 50 watts per channels x 4, really? Not really, more like 20-25 watts, which is not much more than some head units. Used it as bridge when my Hifonics Warror-Eagle bit the dust. Needed the small footprint.



When I had enough bucks upgraded to Kenwood XR-4S.

Installed with a pioneer deh-3000ib head unit and pioneer 6x8 4-way speakers. Sounded decent and got loud (nothing mind blowing for a guy that likes his music loud though), but removed for a day to try powering my speakers with the head unit. Sq shot way up (especially at louder volume) and spl remains the same if not louder than with the amp. Surprisingly still had excellent bass response from my 6x8s even after removing the amp. All in all felt like I wasted money on a 4 channel I didn't really need. Worked, just didn't do it as cleanly as my head units amp, and was overrated for rms power.

I am very pleased with this amp! It was supposed to be temporary, until I could afford to repair my popular brand, pricey amp (the repair quote is double the price of this Sound Storm).

- It is very durable, does not cut out, easy to mount, and can be used with various speaker setups, unlike other amps in this price range.

In the near future, I'll definitely buy another Sound Storm!

-Shipped fast - 4days

-Arrived with everything in box, clean, undamaged.

-HI-Inputs did not work, however the RCA inputs did.

-Looks clean and sturdy.

-Was easy to hook up, and still works today (4 month daily use)

-Underpowered, no where near 50w @4ohm x4.

-Couldn't power 60w RMS - 120w MAX 4ohm speaker.

-Did however power a 25w MAX 4ohm speaker.

-Overall it's clean and looks nice but it doesn't supply what it says it supplies. More like 30watt rms x4.

i think this boy is enough for amplifying your factory speakers , i installed it with x2 pair of jbl's speakers set max wattage 380 for the 4 speakers i don't think this thing pushes 100 watt for them its not close for 20 watt per speaker , don't repeat my mistake if you have a set of high end speaker get a high end amp with them from brands like pioneer,kenwood,rockford

i forgot to mention it make annoying noise with rpm load when you accelerate you will hear more annoying noise from the speakers i think because its trying to reach its peak power .
