There is one speaker on all 4 doors and one sub in shelf behind the back seat.

Here are some electrical diagrams the I thought other 93 GS300 owners may find interesting. :) P.S. As you can see, some of the diagrams are rather large. You might want to download them for viewing in your image viewer.

I am looking for the same thing. 93 GS300... Did you find anything?

I have a 93 GS300 which also is shaking(surging) only when breaking. Getting new tires tomorrow, and an alignment and front-end checkup from Toyota on Monday. Hope the problem can get fixed by that. <_< If I am right, the 93 GS300 comes with Goodyear Eagle GA's with a "V" speed rating from the factory. That is what I am planning on putting back on, but I was wondering if anyone had any suggestions for what tires are good on this car.
