Not really a "little black box"... its got to be at least 10 inches by 5 inches by 1-1/4" thick... It's got an aluminum bracket on it that has two screws which mount to the big plate at the top of the emergency brake, and one more screw which goes into the tube above that which is part of the dash frame. For my install the screw hole in the dash tune just wouldn't line up, so I left it out.
I put the Alpine Amp and wiring into mine along with all 3 dash speakers, and the two roof speakers and the sub-woofer. Doing the wiring took a while, especially the section in the dash between the amp and the stereo, as it takes an "S" bend on the right side of the cluster and around the heater box, that's the toughest spot of running the wiring, the rest is easy.
