I just installed a head unit in my 1999 Mustang (premium sound), and I had to crimp the remote wire from my head unit to the remote wire from my car's optional amplifier for my speakers to work. I have a Rockford Fosgate amplifier coming in to power a subwoofer, and I know I need to wire the remote wire for this one too. What do I crimp it to?

By the way, if anything sounds wrong it's because I don't 100% understand this.

 

Im not %100 sure, but my buddy works for Best buy and hes an installer so he did mine. I want to say he spliced it into a wire from the ignition, not sure though.

 

Run the new amps remote to the same remote lead. It's ok to have 2 on it. If there is a terminal on the factory amp for the remote, just hook it up there. If it runs into the amp internally, splice it in where you connected from your HU. A good way to secure it, being a 3 way connection is a wire cap and electrical tape over and around it a few times if you're not into soldering it. (it tends to come loose when its hot so use plenty) Anytime I had to use elec tape, personally I use some duct tape over it. That usually keeps it together well.

The remote just sends a low voltage signal to turn it on so don't worry about it being too much load. It's basically just a switch.

 

I used a Scosche harness to wire the factory amp to my HU's wire, so would I just tape the 3 wires together? Or am I going to have to dig and find the factory amp?

 

No need to dig for it, you can just twist it into the same spot where you hooked up the lead from the harness/HU.

 

Thank you!
