Oem Amp Adapter

I'm sure this is a common question. I have a 2007 GMC sierra and would like to wire an amp and sub to the factory head unit. I have found some by pac but they don't make anything past 2006 models. Anyone no where I can find a harness at? Thanks

You need to use Line Out Converters, one for each pair of speakers, to wire the speaker wires to, so you then have RCA outputs for the amp, unless the amp you will use has speaker wire inputs. You'll also need a TR4 from PAC to trigger the amp, or find a switched source. With the TR4, you have less risk of the amp popping on startup.
