Installed with fhs501bt head unit and 4 4way pioneer speakers. Easy install. Really woke up the sound. Now I want a sub. Definitely recommend this amp!

Installed this amp yesterday in my 2017 Chevy Sonic to power (2) Pioneer TS-A6970F 6x9’s and the sound is amazing, couldn’t be happier. Crutchfield recommends 10 gauge power wire but I went with 8 gauge and it seemed to work great, ran amp hard for a couple hours yesterday with no issues. Great amp for the money I would definitely recommend.

Getting a Pioneer amp has always been the top of my priority when I started upgrading my car’s audio system. Now that I got this in a nice deal, I’m totally impressed with how it sounds. No problem also pushing my new Kicker speakers. Very balanced sound, nice bass and clear mids. Highs are bright enough but it doesn’t hurt your ears.

Sound quality is good, but the connectors for speaker outs are terrible. Connectors protrude from the body of the amp and space is limited - using better quality speaker wires / crimp on connectors almost impossible. Finding a place to mount the amp was a challenge… it’s dimensions are just a little large to mount under most modern automobile seats.
The unit was nice looking but functionality was terrible. I could not power up even 1 small rca speaker before it would cut out constantly. If you are trying to power headphones this will work otherwise don't count on this little guy powering much of anything.
I'm using this amplifier in 4 channel mode, but not bridged on the B channel as my subs are 4ohms. It pumps loud with very little distortion even coming in from a line convertor spiked off the speaker leads. This is only one day after installing. Lets now see how it handles over the test of time.
Its an ok amplifier for the money, not the best bass but better for running speakers
Works great for 4 channel RCA setup that comes with most after market car audio stereos. I have my front left and right speakers and rear left and right speakers wired direct to the amp and they sound great! Should have done this a long time ago!
Really nice amp. I am only driving a pair of 4 way Pioneer 6x9's and it works awesomely!! Lots of punch and nice fit and finish. Plenty of options for the everyday audiophile at a good price.
Bought 2. One still working after 3 years. One died just after warranty had finished. Sound is good though
