Review on Sound Storm EV4.400 Evolution Car Amplifier - 🚗 400 Watts, 4-Channel, 2-8 Ohm Stable Class A/B, Full Range by Tyler Born

The product is excellent and has a lot of power. The only problem is the terrible hum of the engine. I tried everything to get rid of it, I had to put two noise filters in the audio line to eliminate it, which is ridiculous. Do yourself a favor and buy a better amp if you don't want to spend another $50-$80 on noise filters. However, after installing the filters, I really liked my amp and I'm glad I bought it. Just think of the extra parts that will be needed. That's the only reason I gave it two stars instead of one because it's good with the filters installed.
