Hey I've been searching all of the net trying to find a way to install an amplifier and subwoofer into my Kluger (Highlander). There aren't RCA outs in the back of the stock head unit, but i dont want to buy a new head unit. There is another spare plug on the opposite side from where all of the speaker, power and ground cords are. Im assuming this is an input for steering wheel controls, but wanted to make sure there was no way to some how buy or make an RCA out for this 12 pin plug???
any suggestions
cheers guys
