Re: confused on new stereo and sub instal
If it says boston then it is. you need the premium harness. the cheap one will fit but won't work. The other harness has the 12 volts you need and it also will turn on the factory amp. if you don't want to use the factory amp and harness, you will have to run a dedicated power, accessory, and ground for the deck and also completely run new speaker wires because all the factory ones go through the amp first.
