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!

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

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!

I hooked up my old PolkAudio TS25i (seems most similar to latest-model TSi100, would be a great deal at $150/pair if actually similar) and got outstanding results. After running the same speakers on a mid-grade home component integrated amp by NAD, I think I was hearing a fuller bottom end with the Pioneer 12VDC amp.Although others have noted this amp should prominently market its true continuous power rating at low distortion, not the peak power 500Watts blazoned on its shell, it got louder than desired for a porch dance party, where the absence of walls sucks away sound level, and PLENTY loud to fill my 18x12 living room to party-level loudness, running through the two polk 2-way bookshelf speakers. The presence of that full bass suggests it's got some reserves beyond that.What I'm most happy about is it doesn't gobble up much power. My rig is a prototype for a powerful battery-only portable PA system, using a Yamaha 4-channel mixer (https://smile.amazon.com/gp/product/B00I2J4V5G/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1), Behrenger PowerPlay personal monitor station (https://smile.amazon.com/Behringer-P1-B-BEHRINGER-POWERPLAY/dp/B00GRKXRMK/ref=pd_rhf_ee_s_rp_c_2_0_4/146-7260826-2760957?_encoding=UTF8&pd_rd_i=B00GRKXRMK&pd_rd_r=b81d7dd3-e0e0-40be-a9cb-1208225c60eb&pd_rd_w=5P9ol&pd_rd_wg=oWpZX&pf_rd_p=ea85cb41-868b-4aee-9344-f4ee71f19400&pf_rd_r=ZTY0RMF7TEQ258CX58DH&psc=1&refRID=ZTY0RMF7TEQ258CX58DH) could probably be removed from signal-chain, and possibly some Skars 6x9's (https://smile.amazon.com/gp/product/B019Y7VLUM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) in compact wedge enclosures (https://smile.amazon.com/gp/product/B074QZ5FSZ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1), all running off two pair of Talentcell 12V battery bricks with 12V, 9V, and USB 5V outputs (https://smile.amazon.com/gp/product/B01337QXMA/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1).I had one parallel-jumpered pair of Talentcell 100 Wh (airport compliant) bricks running the Yamaha mixer and Behrenger personal pre-amp, and one pair of Talentcell 132 Wh bricks running the Pioneer power amp. The signal-level bricks are 3/4 the capacity of the power amp bricks. They drained faster than the power amp bricks, even though a couple mixers should be less than 1/2 the power of a power amp? The whole system played about 1 hour of very-loud music, 6 hours at a level you'd turn it down to talk to a friend, 2 hours at background level and probably another 4 hours with amp and signal processing in 'standby': on but not playing music. I'd guess the rig could do >4hours at very-loud volume, no problem, maybe 6 or 8.

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

Great amp for my door speakers and one 12” JL Audio

Makes my 4 6x9 scream!!!!

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.
