Best For Transforming The signal: Kicker Sub box Wire

Buy on Amazon

Next on the list, we've got yet another wire that manages to win our hearts. It's the kicker sub box wire and it's widely considered as one of the best convenient wire you can buy. This remote wire is used to trigger the Amplifier so it will only turn on the amplifier when the radio head unit is turned on and the speaker cable present signals. It makes it sound like the remote will produce 12v with the speaker signals alone. This is used to turn high level input signal (from your rear speaker wires) into a low level input signal so that you can run an amplifier off of your stock head unit. It actually does turn the amp on and off with the car/power to the head unit. This will allow you to use the rca cables to your amp. The output is a very strong 8 volts, which drives the amplifier nicely with the speaker signals alone. It will help give you no distortion.

Great product and works perfectly for newer factory radios
Nice quality and no humming or anything out of the ordinary
