I have upgraded my door speakers on my 2001 S and plan on keeping the stock head unit. I am also considering installing rear speakers by Lucid. What do you all think is a half way decent tweeter mfg. to use ? I am not talking about tweeter location; that has been beaten to death.

 

I used the FOcal 165k2s, I think there more then halfway decent though

 

getting a good crossover to go with the tweeter is just as important. make sure the crossover point is adequate and at least 12 dB.
