Speaker Sizes?

[gadgetguy1288]

I have a 12 SR5 with the standard radio and I want to replace all of them. I plan to change out all of the speakers and add 2 amps and a sub in the back, and I want to keep the stock headunit. I looked online, and tried searching here but didnt come up with anything.

Any ideas?

This is one of many.

I guess my search-fu is weak tonight....


Thanks.
