Can anyone please explain to me what a hi/low convertor does? The back of the receiver has a "preamp out", but its not RCA. what the hell is it for, then? It kinda looks like an S-video port or something. The receiver was made by Volvo. Also, how does one go about wiring these converters, and are there any good brands? I have found that they range from $5-20, is there any difference?! Much Obliged.
it's proprietary to Volvo. check with metra, pac, etc. there may be an adapter to change that DIN connector to an actual set of RCA lines, but I'm not sure. factory radios are always specific to themselves for connectors.
