[quote name='porsche' date='Nov 1 2006, 01:58 PM']the rear speakers have an integrated amplifier. As such, you may wish to stick with OEM units. Call Rick at 570/815-6504 for the parts.

Are you sure about this? I replaced mine, they were 6.5" round in the rear, they did not have amps. The stock were Nokia (8 ohm) and I got a BIG improvement over the stock setup. You may be thinking about the 10 (?) speaker setup, I know nothing about that system.
Also, my car is an '93, I THINK they changed the setup for '94.
As for the front, woofer (mid) it's a 5 1/4 and a 1" tweeter. I cut the stock tweeter out and installed the new tweeter in the stock grille but it took some time/effort.
