Answer
You must have a wiring harness or some way of connecting the wires from the car to the right ones coming out from the new head unit.

The head unit (JVC) manual should have its diagram for the output wires for each amplifier channel.

This link will give you the wiring diagram for your car:

Page 5 shows the wiring for your car.  You can purchase a wiring harness for around $10 which makes it so the radio unit is unpluggable in the event you want to remove it.

You can find the harness at:

www.installer.com and other similar sites including www.crutchfield.com, bestbuy.com and circuitcity.com for example.

Good Luck,
