Does anyone know if the stock head unit has the ability to have a amp wired to it? Just the regular head unit.

From what I've been told, the head unit has no outputs. So if you want to expand you will need a converter for the speaker signal.

You could just use a amp with ( HIGH LEVAL INPUT ) run the speaker wires from the head unit to the amp and then run new wires from the amp to the speakers.
