Pioneer Amp

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

Pros: Great price lots of power

Excellent

Brent from ROSWELL, GA on 11/9/2021

Verified employee review (What's this?)

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.

Verified employee review (What's this?)

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.

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
