    Firstly first thing first. About 5% of the time I try to start my A3 it won't start. Start engine just keeps going. I have a Forge DV with a very stiff spring and I drove about 3-4 miles with the air flow meter disconnected. It's now connected. The car starts if I give it some gas as I turn the ignition though. What's causing this? I don't want to damage my beloved A3.

    The big three, in the car audio world refers to three cables. Engine ground, cable from dynamo to plus and chassi ground. I can't seem to find these. According to this image, there is only one cable going to minus terminal. Shouldn't there b two? Engine ground and chassi ground. [​IMG]

    Earths are under the battery tray, engine ground goes from here to a gearbox bolt on top of the box...
