Search for a wiring diagram to find out which wires are which. As for the amp, your head unit already powers your speakers so you wouldnt need the amp to power them.

yeah your not going to need to wire the stock speakers to the amp lol, that would prolly blow the stock speakers out.... i have 6 1/2 components in the front and rear, and it still uses the stock wiring , i suggest u get a deck harness so u don't have to cut into the stock harness

make sure you have the right harness for the right headunit AND the right car. everything you need you can find with the search button on these forums. if you still need help let me know. i just went through this process. and again you will not need an amp unless you are planning to run a woofer.

Check there for the right wires, you can cross reference with what I posted as long as your factory setup was the same.

Get yourself a metra wiring kit online kit for about $8, metra dash kit about $30, and a lots if speaker wires to run those to your factory speakers from your head unit.(the metra kit wires for speaker wires are not correct, you will only be using power, ground, remote, and illumination wires from the kit so you don't have to cut any of your factory harness plug) You will also need to locate
your positive wire from your factory plug that goes to your factory amp that's located in your trunk, so you can run amp of your choice. There is a wiring diagram for the radio that's very easy to read search for "amp" you'll be surprised how many posts there are about this, you'll see a big difference I sound quality especially if you replace your factory speakers!
Good luck with your project

I have that metra harness with the RCA's, but it sounds like booty when it plays. Why is that?

Heres another link that I have found. Let us know if you figure it out. You can tap in to the factory wiring in the rear if you want. This is what I did. Good luck.

here are the pics..dont laugh at my steering wheel cover or my hairy legs. ahahahaha
still on the stock pioneer sub..waiting until it messes up then get a new one.

speakers are 4 inch kickers in the door and 4 inch kenwoods on the rear..originally i had bought 6 1/2 kickers for the rear but it was a hassle to get them to fit so just returned them and bought the kenwoods

my brother wired this all up for me...

Nice headunit, but IMO its a PIA to always tilt the screen to use the climate control
