Fellas, I think I have a clue, but have not messed with stereos for umm... maybe 17 years? lol.

Just purchased a 2000 Cherokee Sport that came with an OEM head unit. The other day I decided to snoop around closer and in lifting up the back seat, I found some wires... looks like this thing used to push some juice. Under the hood, found a small plastic Rockford Fosgate piece that was wired into the fuse box.

I suspect that once I get a head unit, and want to get a few speakers, maybe an amp, that this thing is good to go, and I probably wont have to worry about the amp draining my battery because the previous owner already set the ground work. Can someone here confirm my find, and if im way off, let me know?

 

You got yerself some amp waaarrin' right thar lol yeah its ready to go, slap an amp and a sub in and you should have some clean sound pushin through.

 

You are wired up for an amp and speakers my friend

 

Reds positive, the thick gray is the ground, and the blue is the turn on wire....
