Customer Product Reviews

Rated 4.5 out of 5★ by 2reviewers.
Rated 4 out of 5★ by Not a 760 watt amp When looking for an amp be leery. Do your research. Now people bad mouth Walmart's electronics but hidden in the rough among the junk are decent products if you do your research. This is a decent amp. You can get it cheaper than at Walmart believe it or not. Also, it's not a 760 watt amplifier. Always look at the RMS rating of an amplifier. That is the wattage it can run on all day long. Look at how your going to run it to know what RMS to look for. Are you running it 4 channel, 2 channel or bridging it. Most people can't crank it and run it all day long like that so RMS is the best determination to use. This is a good 60 watt RMS amp running through four channels. So you can't go wrong. Pioneer is exactly that, a pioneer in audio. I remember back in my day when they were the innovators everyone else looked to. Now their lower end stuff is going to be found in the big chain stores, but occasionally you find some good stuff. Just need to know what your looking for. 02/20/2014
Rated 5 out of 5★ by Very good amp Its a high quality amp for the price. The low and high pass filters work good for subwoofers. I would definitely recommend this amp 08/03/2014
