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

Great sound and slim! Little powerful if you don’t how the right subwoofer, but adjustments can be made and it works great!

Great buy read the instructions first! Powerful amp!

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!

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.

It pump my two 8" woofer with thunder ⛈️ bass.

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

Typical pioneer quality better than average in other words good sounds great with two 300 watt polk 6x9’s

I purchased this Pioneer Amp on June 17th, 2019 and installed the Amp on August 20th, 2019. Once the amp was installed only one channel of the 2 channel amp was working. So I could only get sound out of one speaker in my stereo. I contacted Amazon and they put me in touch with Pioneer. Seeing how I thought the Amp had a 1 year warranty. Pioneer just informed me there is no warranty because (Bargin Flip) is not an authorized dealer for Pioneer so they will not warrant the product. I'm out the money for the AMP with no recourse. Amazon return policy ended on this product on August 18th. I sure wish I knew because I would have installed it before the return date.My advise is purchase your products from Crutchfield or another on line retailer that has an excellent reputation. Being a Amazon Prime member I thought when I purchased from Amazon I would be protected. NODO NOT BUY DO NOT BUY DO NOT BY.I also would stay clear of any Pioneer Products as if I purchased something new and on the box it states is was manufactured on October 2018 they should honor their warrant.
