Was going to upgrade my stereo system, but I'm holding off for awhile. ESRP is $220.00 according to Pioneer's site (http://www.pioneerelectronics.com/Pioneer/CDA/CarProducts/CarProductDetails/0,1429,1997,00.html), but I got them for $149.99. Still in the box, all installation hardware, opened once to check them out but never installed. Trying to break even, college student paying his own way. Any takers?-Corey
