GM-A6704 4-Channel Car Amplifier – 1000W Max, Class AB, Bridgeable Design, Bridgeable, High-/Low-Pass Filters

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.

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.

Bought this amp 3 years ago at the time of writing this. As a teenager, I wanted a better sound system in my super cheap '92 Geo Prizm. This was my option and I don't regret it one bit. I knew Pioneer had built up a great reputation for automotive sound equipment. It was super easy to install once I ran the wire, and it works amazing! Bass, Treble, and sound boosting control tunability is great. Once I dialed it all in, I'm well satisfied with it. 3 years later, still in my Geo today and going strong!

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

Due to the high frequency output setting you can use this and a couple RCA cables to REALLY simplify your cable runs in larger vehicles if used as a speaker amp rather than a sub amp. It's a life saver.

Absolutely disappointed. I love pioneer. But this amp is no good. Nothing but static from the moment it comes on. Missed the return window. So not happy at all. Would not recommend.

Great sound! Great quality! Worth every penny!

Sounds great, gets a little warm but has never failed me and I’m rough on equipment.

Excelente calidad de sonido y potencia. Me gustó mucho como da los bajos, muy naturales, nada forzados. Y los agudos son muy finos.

Powerful with nice variety of settings, It definitely has got kick. Keep in mind it takes minimum 4 gauge wire and a heavy fuse as this is no light weight amp and needs it's power. I without a doubt recommend this amp.

its great as i need and working 100% perfact

Delivered early, and works great running my 6x9 pioneer speakers 100rms it’s bridged For the price I can’t Fault it
