I am keeping the factory head unit and just need to know how to wire it. All the info i can find is on how to wire the the amp into the infinity system BUT i dont have that system. Please help me.

 

You need to get an RCA Audio converter tap into your rear speakers and hook up the RCA cables the remote wire jut needs to go to a wire that is hot while the car is in run if you dont you will keep the amp on all the time and will drain the battery

 

It's fairly easy.
Get you a Line Output Converter. Tap into your FRONT door speaker wires. Best place to get at them is in the front kick panels. Pry up under the sill plates, and they will pop off. they are held only by clips. Then pull toward the rear, revealing inside your kick panels. Find the wire bundle that leads out the door to your speakers and tap into the wires:

Right Front Speaker:
(+) Gray/Yellow
(-) Gray/Light Blue

Left Front:
(+) Dark Green/Yellow
(-) Dark Green/Light Blue


(if you need the rear wire colors, they are
Right Rear:
(+) Dark Green/Light Green
(-) Dark Green/Gray
Left Rear:
(+) Gray/Light Green
(-) Gray/Dark Green

Then run those wires to your Line Output Converter and wire in each pos and neg. Run the RCAs to your amp.

Tap into your cigar lighter (the one on the LEFT) for your remote turn-on Pink/Yellow wire.

Then run your speaker wires to your speaker and call it done!
Let us know how you make out and Good Luck

 

You can get a decent and cheap after market head unit. If it were me, I would spend 30-50 bux and get something after market that sounds better and is easier to work with

 

Its not the money of buying an aftermarket HU its just that I like the looks of the factory HU and want to keep my dash stock.

Also why do I need to use the front speakers verses the rear speakers? Since I do not have the infinity system.

 

so any specific reason that I need to use the front speakers?

 

Go to your truck and play with the fade from front to back. Put it on all the way forward, then all the way to the rear. You will see that the front speakers receive a fuller range of audio signal. The rear speakers in a QC are mainly used for fill in with the primary audio signal coming from the front speakers. So tapping into the front speakers will give you a better signal to work off of.

 

Wired everything like you said to the front speakers and only 1 sub will work.
