Great bang for your buck sub amp! These were very simple to wire up with everything being screw-type connections. Would definitely recommend some wire ferrules to tidy things up. It drives my 500W 2x10" subwoofers cleanly at 2 ohm with straightforward gain and LPF dials. The only thing I miss is a subsonic filter to protect the subwoofer but I would not expect that at this price point.
Pros: clean sound simple screw-type connections
Cons: no subsonic filter

At $142 how could I go wrong? Was $100 off on sale. 500w x1 @ 2ohms is what I was looking for for the sub I got, should work great for my (budget system)
Pros: Pioneer quality at a on sale price .. Bonus! Comes with bass remote Class D
Cons: nothing

PIONEER NEVER DISAPPOINTS
Jeffery from Aurora, IL on 11/3/2024
2017 Lexus ES350
I had this amp before pushing the Kicker L7 CompQ so i bought another one to push my CompQ round 12 inch. Pioneer doesn't upset yet again. This amp handles a 1 Ohm load with no issues, Amp doesn't get hot at all. straight continuous power of 800 watts RMS. This is a must if you want an amp that does t get hot and distort your sound. If wired up correctly, You should turn heads coming up the street. PROPER WIRING AND PROPER CHOICE OF WIRING IS KEY. its like pairing your tv with the correct HDMI cables.
Pros: pushes hard, amp stays cool
Cons: none that i have seen, my second amp

Was a choice between this and the Punch 1000xd. This amp delivers plenty of power. I run 2 4ohm dual coil 10's. This amp is great. I don't need a ton of power. And this is a lot more than what I wanted/needed. It can be as aggressive as you want it to be. It's paired with my lc2i pro. I mounted it on top of my box. It's small to be enough be mounted wherever you want.
Pros: Small Packs a punch Easy to set up
Cons: If you're looking for massive power and versatility, this probably isn't it for you.

Pioneer Amp
Jonathon Ste from Auburn, WA on 9/2/2022
2016 Honda Civic EX-L
The amp is easy to install and paired perfectly with my 1600 watt sub. Sounds incredible. This amp was highly recommended to me and after researching it I am glad I purchased it.
Pros: - Performance - Price for value - Ease of installation
Cons: - Feels a little cheap. - Used to Amazon shipping. This shipped UPS who had a delay and didn't give accurate shipping updates. So I had to reschedule my install date. No biggie overall. Patience is a virtue???

Awesome amp! I paired this with 2 12" pioneer champion series subs, and they hit hard. Very pleased with the output this amp will handle.
Pros: Great power for little money. It does what pioneer says it will. Love the level control knob for changing to different types of music.
Cons: None

Excellent
Brent from ROSWELL, GA on 11/9/2021
Impossible to beat it at the price. 1ohm stable. I measured it at 940 watts at 1 ohm. Definitely under rated. I'm a huge fan. I have 3 of the 4 channel marine pioneers and they are all also under rated and 1 ohm stable.
Pros: Size. Price. 1ohm stable. Makes more power than advertised.
Cons: They don't make one twice this size.

Really like that it is 1 and 2 ohm stable. Biggest factor in buying this amp was being able to have room for future upgrades.
Pros: Price Room for upgrades to system
Cons: Need an extra battery as it taxes the charging system a lot.

Don't skimp on power!
Crutchfield customer from Tucson, AZ on 2/3/2020
Seems to be a perfect compliment to Pioneer's 12" shallow mount subwoofer. Mounted discretely under the driver's seat with the remote dial under the dash.
Pros: Class D = Small footprint, big power. 300 watts to my 4 ohm sub.
Cons: Haven't found any yet.

Nathan from Staunton, VA on 12/7/2019
Great amp for the money! Paired with Kicker CompVR43CVR102. Pushes the subs very hard even with the gain set low. Also Crutchfield is very knowledgeable and I would recommend them to anyone who would like to upgrade their audio needs.
Pros: Affordable Compact design
Cons: None at this point
