Hi I am removing the factory amp and factory 8"sub from my 2005 Ford Territory Ghia and replacing with an aftermarket 8" sub and amp in one. Im wondering how I should go from here? How do I no what wires I need and what I dont? also the wiring is very small gauge will i be able to use this wiring or will i have to run new bigger stuff? Any help much appreciated I have attached images.

Fuse should be located under the hood within 18" of the battery. Yes you'll want some chunky power (and ground) wire for an aftermarket amp to be safe. Not only for ampacity but for the sake of just having a bit more insulation for protection.

You may or may not find what you need to plug and play from the factory plugs at Crutchfield, otherwise Google is your friend as far as figuring out what factory colors are what.

Sadly replacing a factory amp isn't quite as simple as replacing a factory head unit. You usually want LOC to provide RCA input source, you'll need to run power from the battery back and you'll need a solid ground, then you may or may not easily be able to connect the speaker outputs from the new amp to the factory locations, and you may need to run REM wire from the HU back to the amp as well.

His amp has the built in LOC ..
 
The little white rectangle plug is a built in loc converter ....that enables you to run your headunits speaker wires to power the input of the aftermarket subwoofer ....you wont ne ed d the rca Jack's
so how do i go about wiring into the built in LOC? and how can i work out what wires for what? and will i be able to just use this factory wiring?
