You guys have the upgraded stereo? I know it's an option on the 05s, but not sure about the 01-04s. I have the regular 4 speaker stereo.

I'm skipping rear speakers for the time being. I don't feel like spending the money and doing the work to install them. Once my install is done, I'll take a seat in the back with the stereo at a low volume and see how well I can hear the music. If it's too quiet back there, then I'll look for new rear speakers. I'm using a tuner head unit, so all my speakers need an amp. The fronts will be getting 100w each and I have 2 spare amps to use for the rear if I decide to run rear speakers. One is an Alpine 25x4, the other is a Pioneer 30x2. The ONLY reason I have for rear speakers is my kids...they like to hear my music. If it wasn't for them, I'd never consider rear speakers because I don't want to mess up the sound stage.
