    I am very impressed with this little sub amp. It is very small so it fit well into a tight space I had for installation. Being 1 OHM stable, it paired nicely with the Kicker 2 OHM dual voice coil subwoofer. It sounds awesome and puts out a ton of power!

    This amp is very small but put out a very large amount of power. I have it wired to 1 ohm to get the most out of it connected to two Kicker CompR 12 and it’s more than enough power to push them. Pure bass pours out this amp.

    I was looking for an Amp that could handle my sub without having to struggle for power and this was perfect, not that old bulky style, which is nice when comes to mounting in tight spaces, absolutely amazing.

    Easiest amp I have ever installed and I love it , thinking about purchasing a second one but it sucks so much power that it literally makes my headlights dim , when the bass hit , I think that it would be even better combined with a line crossover, so I still building my sound system and will purchase a second amp, I highly recommend this amp for a pair of ten or eights

    Small and easy to use. It adds aloud sounds to the speakers. Kicker is the one to get. Make sure you get the warranty with it 4 years is your best bet.

    Was looking for a good strong compact amp that didn’t take too much space. This one did great and I got it while it was on sale for fifty off which made it even better. I had Best Buy’s technician which is highly recommended so that they can help tune the amp after so you could get full potential from the set up.

    Great amp. Kicker makes some of the best products on the market today. You can use iy in several combinations. I have mine running a single Kicker comp C 12 at 4ohms and 300w. 300 true watts.

    Installed in my 2019 Honda Passport, paired with a 12” Kicker CompR ported enclosure. RMS @ 893. This amp hits extremely hard!! Even with the bass level low. Highly recommend this amp.
