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

Sounds really better than expected. Looks great and inconspicuous. I have mine wired at 2ohms. It holds stable with no drain and no overheating. Easy to connect and the auto on/off feature is great. You'll really enjoy this amp. It provides a great sound over stock any day. And if we're being honest, i actually bought 2!

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.

Pioneer brand is always capable but not always overly impressive. This one delivers what it claims if you know their language and don't expect too much. Overall good sound and nice look. Lacks in beefiness and I'm not a fan of the terminals. It is an entry level amplifier that can be purchased at Wal-Mart so I always take these products with a bit of speculative curiosity. Still Pioneer quality just not the most impressive item in their arsenal.

Haven’t plugged it and set it up with my black diamond 15 inch subwoofer hopefully it’s enough power to get a good steady sound until I can upgrade

Initial testing was impressive. Unlike most audio advertisements, this one is accurate! It's actually far more sound volume than I'll ever need or use. Knowing that audio specifications are usually blatant lies, I bought the cheapest head unit I could find, with the features I wanted. I ignored the output power ratings. It actually sounds decent but all the credit goes to this amp. Installation will be quick & simple. I'm using the factory speakers in my old Ford F-350 4x4 truck. I plan on buying another for my desk. Driven by my computer and connected to some Klipsch bookshelf speakers. I know, a bit overkill but like I said, everyone else can't be honest with specifications so at least this way I know what I'm buying.

as described

1 channel works. Seller stated they were sending a return label and they never did. Do NOT recommend this due to poor seller and poor quality control on pioneer end. Unit was new in box it appeared

Previously I had a Crunch amp and it gives the alternator whine when I press on the accelerator. Tried many ways to fix it with capacitors and better grounding but it can only be fixed by turning down gain all the way. After changing to this, it sounds really clean even with the gain being turned up by default, despite having reused all the old power and grounding cables.

Very good product, pioneer is still a very reliable and amazing amplifier maker. I only wish the amp came with a remote gain switch and installation hardware , you know the gold plated stuff. Price was very affordable. I also bought the 520 watt 4 channel amp and they work great as a team. I just wish pioneer would sponsor me or send me samples to tty and rate.

Cela fait 1 an que j'ai ce produit et rien à dire de très bonne qualité et fait son taff

Super bien !

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.
