460 sound

Are you talking about the Mach 460 sound system? If so, I believe that came out in the mid 90's. So if you have it in your thunderbird it's added in....? I always thought about doing that. It'd be nice to keep stock components but sound nice so I could say, "yeah, that's a factory sound system" and be mostly truthful. :D
Anyway, for you, I'd say the easiest way is to use that adapter to pick up 12v sources, ground and dimmer, then rerun speaker wire to your speakers. This uses the headunits built in amp (but won't sound anywhere near a 460 or even thunderbird premium sound system IMO).
