The usual items you will need is a wiring harness and an install kit. The wiring harness will allow you to hook the radio to it, and then just plug into the car. The install kit will have all the little mounts and trim rings you might need. Each of them cost around $15 each, unless you have some crazy set up. Your's doesn't sound like that. You can purchase these items at www.crutchfield.com and you can search for your specific vehicle. Hope this helps.

Hello i just recently bought alpine speakers for my eclipse 2003


mostly because the subs in the back are probley using more amps than the ones in the front in the front should be used mostly for vocals and your bass in the trun so maybe trying to unhook the ones in the front from the sub and just leave then hooked up to the cd player where you can hear the vocals really good and leave your subs in the back hooked up to the amp

1. you can go here and get a wiring manual with right model #.
http://www.alpine-usa.com/US-en/support/
2. The red wire goes to ignition switch/key.
Yellow wire goes to constant hot/battery.
Black wire is ground.
Blue wire is for power antana you do not need to hook that to anything.
You can look at this diagram for a little more help it is not your radio though but it will give you a reference point to look at. All radio red,yellow,blue,black wires are the same on all radios.

go to page 42 on this site for wire diagram.
Good luck with problem.
