Sunset has an ad in this month's Panorama w/ a price or $79.86
Best I've seen so far...
If you already have door speakers (the M490 or M680 hi-fi package) you might want to tell them you have an '03. This way you also get the extension harness at no charge. Currently you won't need it but the extension harness will allow you to power them off the AMP in the front trunk. Your current amp (4ch x 40W) will not power these so you will have to run them off the head unit/radio (at 18W) for the time being. However, 6x40W amps can usually be found on eBay for ~ $50. It's a worthwhile upgrade to drop one (a 6x40) in to power these speakers evenly w/ the door and dash speakers. This way, you won't have to spend money on the extension harness later on...
Adding rear speakers is a nice addition. Act surprised when you open them
