13 Impreza Sport Limited with the nicer (Non Nav) stereo.
I want to keep the stock stereo even though its not nearly as good as an aftermarket. I live and work in a high crime area and thieves generally don't mess with stock stereos.
I installed Polk speakers.
If I wanted to add an aftermarket underseat sub, are there wires somewhere from the factory? Or would I have to use the rear speaker wires?
I will probably amp the front speakers too, would like to keep all 4 speakers and add a sub if possible.
