Review on 🔌 Metra MC918-20 20ft 9-Conductor 18 AWG Twisted Multi-Purpose Cable by Tim Larsen

Ideal for adding a 5 channel amplifier (if compatible) using the factory head unit's high level inputs rather than a line out converter to a bunch of low level -Add RCA cables. Using a wire harness adapter, I soldered two sets of this 9-wire speaker wire; first from the head unit output to the high input of the amplifier and then from the speaker output of the amplifier back to the factory speaker harness which was disconnected. This worked well with my Toyota Tacoma 2021's stock audio upgrade. It only took 10 feet of 9-wire speaker wire through the center console under the driver's seat.
