    • Awesome Amp
Style: 4-Channel - 1000W
Really great amp for the money. Good amount of adjustability, produces good sound and is plenty powerful. The bridging feature and selection between 1, 2, or 3 channels makes it very versatile. Doesn’t get very warm powering (2) 6.5” door speakers and a Kicker 8” woofer.

    • Good amp for the price
Style: 4-Channel - 1000W
Good amp for the price. 4 stars cause it is a budget amp. It does the job tho. If its running hot, be sure your gains are set correctly for gour speakers. Use a voltmeter. Pushing a kicker comp c 10" 4ohm in a ported enclosure bridged on channel b. 2 pioneer pro 6.5 mid drivers on channel a and only gets a lil warm. Purchased another to hookup to my 6x9 and 2 more pro 6.5. You can spend more for better amps but this will definitely get the job done if your on a budget. Again, gain settings are very important ... show more

    • Fantastic Amplifier!!
Style: 4-Channel - 1000W
I love the power and performance of this amplifier. It fits nicely on the ledge in my trunk and looks very professional. I purchased this Pioneer Amplifier in August 2019 along with an in-dash Pioneer stereo, speakers, and a 10-inch subwoofer. I had it installed professionally at Best Buy, which I highly recommend. My entire system has performed flawlessly for just over five years. My Pioneer 4-channel amp is truly a game changer. ... show more
