Help--what else do I need for install.

I have a 12 DCSB and I am in need of guidence. Right now I have these two older amps

Older Kicker 600.1

Both amps work great and have been sitting around for a couple of years. Aside from the amp kit, RCA convertor and the +/- distribution blocks what else will be needed to hook these amps up to the factory non nav HU? Will I need a signal processor? If I need a signal processor do I need a 4ch rca convertor or 2ch?

I was thinking of this here if needed

Any info would be helpful. Thanks

 

My amp had speaker level inputs. I have an alpine 5 channel amp. I originally orderd audio control lc6, got lost in mail,Amazon refunded money. Just tapped the two rear speaker wires going to speakers into harness that came with amp. Worked well and saved $125.
