I have just bought a high to low level converter from Jaycar. I am trying to run an amp (which is connected to a sub) using my factory head unit (brand new factory corolla deck in a 1988 toyota Supra). I am Car audio illiterate and am wondering if someone with more knowledge than me can tell me what it is exactly that i need to do to get this up and running. In simplest terms would be appreciated. If you would rather PM or email r.moore@bigpond.net.au that would be fine.
