Easy to hook up. The amp turns on by just the speaker wires being hooked up so no remote wire needed. great sounding.

I was surprised how well this thing hits! I’ve been out of the subs game for awhile so I wasn’t sure what would be the best route to take, I’m very pleased with the sub and amp. I was first worried about the size of amp, but it does the job quite well. Can’t wait to pair it up with all the door speakers. I also did not need to run a remote wire as the dongle I got recognizes the power to the amp through the rca cables

Bought this as a christmas present for my son with the intentions to install it ourselves. Fortunately we decided to have the professionals at Best Buy do it. We were informed that the amp was not compatible with the subwoofer. They said it may work for a while, but wouldnt be good sound quality and may eventually short out the components. They also stated that the wiring kit is not thick enough for this application anyway and may cause a fire!! Like I said, we are lucky we didnt install it ourselves! Now HiFi- soundconnection wont accept return of their brand new, in the package, incompatible components since its past the 30 days return window! I never write reviews, but I had to for this one. Im Hoping this keeps others safe and saves them some money and headache.

I installed this kit in my 2011 Ford F-150. This is a good kit for the price. Kicker sub sounds amazing and amp has enough juice to power it. There should be a 4-gauge power and ground wire in stead of the 8, but even still, def worth the money. I will upgrade my power and ground at a later time.

I replaced all speakers w Kicker KS in ‘22 Ford Bronco myself. Had 2 amps installed ( for the 6 new speakers, 1 per this order) along w this Bass speaker. AMAZING what the 12” sub added to the sound.

have to say I'm extremely impressed with this package. Not only did it fit perfectly under the rear seat but it sounds great as well. I was a little worried that it might not be enough for me as I'm a go big or nothing kinda person. I really wanted a Kicker amp just because all the speakers in my truck are Kickers but I'm just going to leave it alone. Perfect match.
