luckily my 2000 S came with the touring package, wind deflector four channel amp, six speakers (including rears) and the sound tuner-thing under the head unit.
This has to be the best sound set up in a convertible out of the box I've ever experienced. At speed with the top down its loud and clear. Maybe too loud because I can't hear the engine for gear changes.
Very deep rich sound from the dash speakers but the rears are not really equal at all. To have a 'surround sound effect' the out put has to be susbstantially lowered up front. So its a trade off.
