The Amp in the rear of the car has front full signal for both right and left and is used for powering the door speakers. In this car it is considered the easiest place to wire a LOC.
see this thread for a lot of info on the stock amp, you need to know which wires are for input front right and left, it'll be 4 wires, and remote on is also useful.

further in the thread it describes how to use metra harnesses to wire a LOC to the inputs without cutting any factory wires, costs a little more, but makes the work easier, and 100% reversible. |
Please do correct me if I'm wrong, I'd love to learn, but here goes.
After going through the thread, it appears that they're all attempting to exchange the original stock amp for an aftermarket one and go from there. What I'd preferably like is to install a secondary one purely for my subwoofer. If it means anything, it's a 1-channel class D 500W amp.
I read a bit further into the thread talking about the metra harness but it involves practically building your own. This is for the guy who has absolutely no knowledge when it comes to wires but is stubborn enough to want to try the process without the help of a shop.
In addition, why would it be best to wire from the rear amp than from the front headunit? Wouldn't the headunit be a smarter option than the rear amp as everyone says there isn't much power back there or something alone those lines?
My concern is I don't want to blow something like a rear speaker or two. Yes, it being fully reversible would be great but at this point, I'd love to get it to become functional as I don't intend to get of this car for at least the next 4 years and by then, it's bound to be in some sort of accident or handed down.
