Well I have a 1994 Eddie Bauer and I just had my back door speakers replaced and those were 6x8. I was also told that the front door speakers are the same.
6x8.
6.5 I believe
were is icv located on a 1994 bmw 325is
the mid-rear speakers are 6.5
6.5
5x7 or 6x8 all around
4x6 inches. Many aftermarket speaker manufacturers make a direct replacement in this size.
For any car you can find parts, specs including speaker sizes on these websites. Metraonline.com, scosche.com, crutchfield.com
Everything I can find indicates that all four are 5x7 inch speakers.
The 1994 Toyota Previa typically features speaker sizes of 6.5 inches for the front door speakers and 4 inches for the rear speakers. The vehicle was designed to accommodate standard speaker sizes, allowing for easy replacement or upgrades. Depending on the trim level, the Previa may also have options for additional speakers or audio systems.
if you have the Bose speaker system your looking at 3 6.5"... one in each door and one hidden in a panel in the trunk
4x6 in dash and 6 1/2 inch in doors
