Best For Transforming The signal: Kicker 4 Channel Car Amplifier connection

Buy on Amazon

This is used to turn high level input signal (from your rear speaker wires) into low level input signal so that you can run an amplifier off of your stock head unit.

The output is a very strong 8 volts, which drives the amplifier nicely. It makes it sound like the remote will produce 12v with the speaker signals alone.

• Super simple to install, remote works perfect
• A line out converter that doubles as a remote output
• Works great & makes installation simple
