How do you hook up an amplifier kit to stock radio?

Answer 1

Most factory radios are not set up to be connected to amps. You can try a few tricks to get you started though... 1.) If you have access to the wiring harness in the back of the radio, look for two RCA jacks (male or female), and an orange or blue wire (remote wire) that wouldn't be connected to anything except the radio. If you do have these, simple extensions can be purchased to run those wires to any aftermarket amplifier. 2.) If the car/truck came with a factory amplifier (you would know if it did), you can simply remove that amplifier and have full access to all wires needed for an aftermarket amplifier. 3.) If you were feeling up to the challenge, you can disassemble your radio and look for a pre-amp. After a few modifications, you can wire the aftermarket amplifier through the original pre-amp. 4.) Last but not least, most aftermarket amplifiers need only a few wires to get started. A power wire (RED - always hot), a remote wire (Most of the time a BLUE wire - only has power when the radio is on <<hook up to a toggle switch in this case>>), and your audio inputs. There are a few amps that do not require RCA inputs and you can simply split off an existing rear spear wire and tie in to the amplifier.

You need what's called a line converter, this will tap into speaker wire going into one of your rest speakers. Then you have a power wire with appropriate fuse from battery to amp, a good ground from the amp the the chassis of the car and a remote wire from amp to switched power 12 v for car. Run your rca from amp to the line converter.
