eason, I was in your position a bit ago, and I put in the Pioneer Avic-z3 as a new head unit. I ran into a bit of a snag when I tried to connect to the Bose amp. Bose has a proprietary fiber line(MOST bus) running to the Porsche head unit, that will not work with any other system. I reiterate that installing a new radio head unit will make the speakers in the car useless without modification. I had an inverter hooked up to a set of computer speakers for a while in order to have sound in the car. As of this weekend I just installed new MB quart speakers and amp, and it sounds so much better than the stock Bose set. I did do some research about keeping the speakers and upgrading to a new amp. Bose says that all of the speakers are running a fiber line, but the speakers are actually a copper line that you can reuse. There is a problem that arose when hooking up a new amp to the old Bose speakers, (feel free to correct me on this) the Bose speakers are 2 ohm speakers, when amps usually cater to 4 ohm speakers. Unless you find a good 2 ohm amp, you can get a 4 ohm amp and put resistors before the speakers, but this is not recommended because it will only be time before you wear the speakers out under load. The options that you have if you are installing your new head unit is to either just install a new amp(which a good amp will make the Bose speakers sound better) and wire to the existing speakers, listen to the boxster s' own sound system :), or the best option(what I did) is to completely revamp the sound system. If price is a issue, installing the speakers by hand and getting them from sonicelectronix saved more than half on the system. I do recommend spending the money and installing a new set of speakers, because with the top down on the highway, these speakers sound better than the Bose stopped top up. If you need any help with your system, feel free to ask.
