Almost perfect

"Sub sounds great now that I have it all installed. The instructions were not clear in regard to a couple things. First, the light is supposed to be green when the sub is on not red as stated. Second, when not using the RCA for signal there is a second ground wire that is option to use if hearing static. ( there was nothing written about it in the instructions ) Lastly, the amp wire kit was a gauge smaller than the manufacturer recommended (thankfully due to the distance I could use 10 gauge instead of 8) Also, the inline fuse did not cut off power correctly when removed so I am having to install a new inline fuse holder myself so I do not have to replace the entire thing."

Great little sub

"I was a little apprehensive when the box arrived pretty beat up but everything fired up and sounds great. In fact it’s a bit too much and I’ve had to turn it down. This DOES NOT fit under my front seat bc of the heat duct of the rear so it’s in a spot I’m not thrilled about but that’s a Chevy issue not MTX or Rockville. The remote gain control only seems to work as on/off but I haven’t had time to play with the settings enough to see why."
