Crutchfield Customer Review (What's this?)
2011 GMC Sierra 1500 Crew Cab. The install was pretty straight forward and I would allow 3 - 4 hours. The bracket that comes mounted to the "highs" amp is designed to fit without the power brake pedal feature. This is a known issue and they emailed me an addendum for amplifier mounting with the power brake pedal which is just to rest the amplifier on top of the air duct that's under the steering column, it's kept in place sort of when you reattach all the panels. I cut out a few pieces of rubber I had lying around to prevent a few potential rattles from this install method. Next I found that when I connected the power wire for the "highs" amp it pushed the connectors from plug so I pushed them in and reconnected. Now I have music from the front two channels only, no subwoofer. I replaced the fuse for the sub amp as they one in the kit was faulty or had blown even though it visibly showed no evidence. I contacted Kicker about the rear channels not working and they informed me that they sometimes have trouble with the harness since GM has the patents and they can't make it exactly the same. After disconnecting and reconnecting all the harnesses I get a 3rd channel intermittently. I will say that the bass is great and the highs are noticeably crossed over and cleaned, however I do find that the sub tends to be louder then the rest of the music. I plan to return this system as I'm tired of trying to get all 4 channels to work.
Pros: Tight clean bass,
Cons: Poor harness connections.
