Anyone with an opinion on adding rear speaker package?

[AUDIOGUY]

I was wondering if anyone has installed a rear speaker package in their Boxster? I was on Ebay and noticed Suncoast Porsche selling an OEM rear speaker package with wiring. I have an 01 S and the standard in-dash CDP. The system has 4 speakers now with dash and door speakers. There is a small amp in the front compartment. Can anyone tell me if this add on speaker kit is semi-easy to install, will it work with factory wiring, and is it worth trying?

My alternative is to replace the whole setup with a new head unit, 4 channel amp, speakers and a small sub. Obviously, cost on the OEM kit for 200.00 is less than 2k for a nice system. I am leary of upgrading the stereo at this point because I find myself listening to the exhaust note of my B and B!

Thanks in advance,
Joe
