    I bought this amp to push my 4 speakers. Sound is great, make sure to get a good pair of RCA cables since that will also help make a difference. Tried on 6x9 Kickers and JBL speakers and I like how the Kickers handled better than the JBL. With the JBL's you reach a point where turning it up more diminishes quality of sound. JBL's have a lower RMS handling power compared to the kickers.

    This was my first time buying an amplifier and it exceeded all my expectations. Sound is loud and clean with the gain left at the default normal position. Stays cool and hasn't over heated.

    I bought this pioneer amplifier to go along with my Pioneer cd/Bluetooth music player. They work great together and the music sounds perfect in my car. I choose Pioneer products because for years they made great products and now they still do. I am very happy with my purchase.

    Great inexpensive amp to power kicker speakers in an older muscle car. Now I can actually hear my stereo over the sound of my flowmasters.

    Got it hooked up to some 100w speakers in the front and 80w speakers in the back and it is driving them better than I expected. Tremendous difference compared to stock.
