Jus wonderin if anyone knows the exact dimensions of the 01 IS300 tweaters and speakers and if they know of some good replacements for the stock ones.

 

that would be "tweeters", like a bird.

 

Tried to make this look right but here's the sizes either way....

Speaker Specifications
Location----------Size
Front Speaker------6.5
Front Tweeter-------2
Rear Speaker-------6.5
