Great amp, with awesome sound and definite value for the money
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!

Awesome Amp
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.

Fantastic Amplifier!!
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.

Powerful, clear-sounding and modestly-priced (12VDC power runs efficiently off Talentcell...)
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.

Decent price to run 1-15inch sub, let’s see if it works and hold up till I can upgrade
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

Accurate Advertised Specs!
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.

Received a Dud! Don’t buy!!
0 Stars. I received a dud. It wouldn’t even power up. Waste of my time. Very disappointed.

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.

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.
