When do you want to listen to these fine, very fine (high dollar) speakers?; when the car is parked with the engine off. I posted this last summer:
"Just something for you to consider. I replaced my 2 rear "subs", if you can call 6 1/2 inch speakers subs. I don't know about you, but with the top off, and/or windows out, there is so much wind, road, and exhaust niose, that I have the balance shifted primarily to the rear speakers to hear next to my ear(s). All I was getting was the lows because of the crossover (capacitor). All this said, I replaced my 2 rears with full range (dual cone speaker/coax speaker, whatever you call them) speakers that had a GOOD low end, and loose the capacitor crossover. Now with the balance to the rear, I hear the "full range" of the sound/music. Oh, the stock amp driving the rears knows no difference."
I install "MA AUDIO" SY62F(2) speakers.
I also replaced the head unit (to CD)which makes the real difference in the output to the amps.
