What your solution to the poor speakers in the 986?

[messing]

Well I continue to enjoy my 986. The weather has been good, the top is down and the radio, well that another story. My 99 986 has the factory head unit w/o Nav a six disk in the truck and yes a tape deck behind the flip down face. The tape deck really cracks me up. Everyone thinks my car is new and then I flip down the deck face. To funny. Anyway, I have flown my drivers speaker and it’s time for an upgrade. I'd love to hear what you all have done to improve your audio system. I am not looking to do anything crazy but I would like some rear speakers. I like the Porsche head unit, really just because it say Porsche on it and it works fine. Any recommendations on speakers or adjustments.

Thanks,
JM
