Rear speaker wire color

[machda]

Hey guys i just bought 2 12inch JL audio subs boxed already, with Zapco AG350 4 channel amp. the wiring is already done in my car since i bought it used.There is a red 10 gauge amp wire going from my battery to my trunk its missing the fuse any one know what size the fuse is? the way i am trying to wire this is to the stock deck. As it was previously installed by someone else there is RCA cables behind the deck. how i would i go about installing those ? to rear speakers?
i have posted pics of the speakers and amp

it seems like the previous owner has already tapped the signal and the LOC is hidden behind the dash.

If this is so - connect the RCA, and power cables to the amp. Ground the amp to the chassis. Put in a new fuse, and bridge the amp to the subs
