Need helping installing Sub into 2002 mustang
So I recently bought a 2002 Mustang GT convertible and was trying to install a sub a had laying around in my house.
The previous owners didn't tell me much about the vehicle but from my own observations i have all of the original Mach 460 speakers as well as the dual amps mounted in my trunk.
I discovered Two speakers cabled running from my Head Unit all the way back into my trunk and they were not connected to anything, I also found the large copper wire attached to the wheel well as a ground but also was not connected to anything. I was curious if anyone could give me some advice into installing this single 10' Sub into my trunk since it is apparent that the 460 Amps are pretty hard to deal with.
This is my first attempt to setup speakers in a car before so don't blame me if ive missed the obvious lol!
Some help would be great! thanks!
