Small output power and sound quality that leaves a bit to be desired. Defiantly better than running speakers off the head unit but for a few dollars more there is much better options

A great little amp for the price. It is quite compact but still has pretty spacious terminals and the connections are laid out well.I am using the on board filter to trigger the amp rather than the remote wire and it has worked flawlessly so far.Fits well under a seat too.

Bought this GMA3702 Amp to power a 12Alpine Type -S Sub. Was a little hesitant that it may be under powered, however it kicks very well indeed ( main speakers are only running off a Sony 4x 55W Head Unit so it doesn't need to be insanely loud to punch some nice lows out). It does not have an adjustable cross-over however most head-units do these days and it does have a HPF to roll off the higher frequencies getting through.Only downside was the first unit I picked up in store was faulty. Though SCA was hassle free with exchanging the next day and the next one has been fine since.

As advertised, easy set up. Am using bridged to run subs. Works perfectly
5 stars, not because it's the world's best amplifier but because it's 100% what it claims to be. A great budget solution and it sounds fantastic. My rear speakers are powered by the stereo and the front speakers (aftermarket) are powered by this amp and I had to turn the gain down to only about 20% to nicely match the volume from the other speakers and the sub. Ran it loud for about 3 hours on a long cruise and it was only just warm to the touch at the end. Didn't think I could go wrong at this price but even still I am pleasantly surprised. This little amp saved the day.
Great quality . Simple DIY Install . Bridged channel runs sub really well . Happy as with the product.
Works better than I thought it was going to and I actually have it set at a lower setting because it had more volume than I thought it was going to have. Great price and the song quality is perfect.
Love the amp. Always had pioneer amps in all of my systems and they’ve never disappointed. The only thing missing would be the remote gain control. Otherwise small in size but big In power
The small size of such a powerful unit with a name like pioneer and a small price tag as well couldnt ask for a better product and eBay was the best place to find it!!!! WOBLEY MOBLEY
I have a pioneer amp that this replaced by 4 generations. Other is 18 years old This new one doesn't sound clean like my old one that still works. Thought I was upgrading. Spend the money on a quality amp.
