I have an Infinity Basslink sub that I'm selling if anyone is interested. Just make me an offer. I'm not sure how the factory deck is setup, but if you can find where the remote wire and preout wires are coming off of the harness you could run this off of the factory deck. (It would be the same wiring that the aftermarket subaru sub would use.)
i know it says make offer. i am interested but could you list what you rlooking to get for it so i dont low ball you, cause thats prolly what i would do.
