05 non bose tahoe..

[Walkercraig01]

i bought this 05 tahoe that is non bose.. has a cheap aftermarket head unit.. by cheap i mean the 20 dollar dual walmart head unit. anyways.. i was checking stuff out yesterday and i noticed there is a speaker wire ran to the sub box in the rear.. now this one obv doesnt have a sub. so its just a wire in the hole.. did they run the wiring even in the non bose models? it looks like aftermarket wire as its blue/black. but im looking to trace it to see if its useable.. it doesnt have power to it currently so im lost.. nothing matches it in the dash either.. so im kinda stumped.

i was wrong it does have power to it.. also has the rear speakers so 6 plus the extra one. i thought non bose only had the doors??

I am not familiar with the non-Bose systems, but you should be able to trace that powered wired as it may go under the door sills and you can find where it's connected.
