So I’m wanting to add a sub to my factory system (including factory HU) in my 05 supercrew. Got a couple questions that I can’t seem to answer:

1. When tapping into the factory 6 disc head unit to get the RCA outputs, how do I find out which wires are the positive and negative and right and left?

2. I have an amp already that I want to use (Pioneer GM-5000T). Its two channel, and has 760watt max output. I’m looking at getting one Rockford Fosgate P3S 10”. I don’t know if I should get the 2 ohm or 4 ohm model, or why I should desire one over the other. Also not 100% if my amp and that sub will work well together.

Thanks in advance for the help.

your amp is fine for 1 p3 shallow 10 get a dual 2 ohm vc sub or single 4 ohm vc to use with your amp. so your amp will have the right ohm load so you get the most out of it. im not sure if they make a single voice coil i could only find dvc models. if you get the 2 ohm dvc model you will have to connect the wires +-+- in series and bridge your amp outputs ( to make sure that each coil gets the same amount of power to it). if you get a 4 ohm svc (again not sure if they make it) you will just wire it +- to your amp after bridging the outputs.

on the wiring behind the hu it has been awile since ive looked back there and dont remember the color codes.

 

I can't remember who posted the wiring color codes here but I think this will work for you.

Hey 05199 have you torn into it yet? I am going to start my own install Monday. Good Luck, any ???'s give a holler.

 

Hey guys, thanks for the info. Havn't torn into anything yet, just planning ahead, i'm about to order sub and box, might get started on wiring soon. Thanks again for the help!
