Need to splice car stereo wires to Pioneer deh-p2600 decks harness. Include amp?

What is your question?

I had my stock head unit go into safe mode as well, but, read into it too late and the tape deck now unusable. Oh well, besides the fact I had just installed Led my 4 brand new Kenwood 6.5s.. Uhg!! So, a month later I have a paycheck that is all mine(sadly I work at autozone and still can't find the right info I'm requesting in the following lines, lol) , I buy a Pioneer deh-p2600 deck, a cheap dual 500w ten in sub in a box and a kicker 300dx.2 amp, all the wires and rcas, yadda yadda.. Now I notice that my cars wires are completely different than the decks… Oh no, right? No, I download both diagrams and (think i) have it connected. The moment of truth… Turn the key to acc and… Nothing not a light a click or even a pop… So.. My kind fellows, I need advice… I still need to do: *run wires for amp *get power to deck *avoid buying the adapter because I am a broke joke. *identify and check all related fuses. *? give thanks to this site and any of you fine gentleman that can help me with advice. Instructions, pix, anything.. *I'm sure there are a ton of things left out, but this is my first install.
