i have a new cd deck and a few speakers to go into my subaru gl hatch, but the wiring in my car is messed up like a past owner tryed messing with it and they got it all screwed.. i want to install something in my car,, becuase i have no music right now, and its lame just listening to the heater in the morning, plus ive looked for installation kits but nobody has any from what i can find. i didnt want to go to a professional place to install it, but i will if i have to.. what should i do????
