[QUOTE="alum, post: 8669554, member: 676622"] Hi there, I'm new here and need some wiring help for my [B]2007 Lincoln Town Car Signature L[/B] with [B]factory THX sound system with Navigation[/B]. I want to replace my factory head unit with one with USB input but hopefully keep the factory amp and subwoofer amp. I apologize for not knowing any of the terminology. I believe the factory head unit is a Pioneer. It does not have rca outputs. It has 5 pairs of 22 gauge wires (shielded) running to the amp in the trunk made up of FL+ FL-, FR+ FR-, LR+ LR-, RR+ RR- and SUB+ Sub-. I have a dual head unit on hand that I will use to experiment with. It has speaker wires out as well as Front and Rear rca's and a Sub rca. I'm guessing the factory head unit is just a pre-amp so I can't run the speaker outputs directly from the new head unit to the amp. Is there a way to convert the rca pre-outs on the new head unit to speaker lines that I can connect to the original wiring? Another option I was thinking of was a Scosche OEA-4 Factory Amp Interface. This looks like it will match the speaker line output to match the amp. That doesn't help with the Sub pre-out though. Any help would be appreciated, thanks! [/QUOTE]
