I really like the stock look of the STI's head unit and climate controls. I don't want to get a new head unit because i like the look. I was looking for some information on hooking up amps to a stock headunit that does not have preouts. I found a few line to rca converters on ebay and just wanted to ask here if anyone has any information on what exactly needs to be done to hook up the subs. Im looking to run 2 amps, 1 for the subs and 1 for the speakers. If anyone can recommend some brands for the line converter or links to instructions on similar setups i would really appreciate it. Thanks in advance.
