Follow along as the sound crew at Cars Etc. Audio in Turlock, California, hooks up a complete audio system by Pioneer. The step-by-step process begins with removing the old stock radio unit with speakers and replacing them with a Pioneer System—deck, speakers, and amplifier that easily plug in from your main wire harness. This quick-and-easy hookup continues with a few soldered wires to the speakers and some RCA jacks that get plugged in under the seat-mounted amplifiers.
