Suggestion for a sticky Options

[SinisterWhisper]

I myself just got done purchasing my speakers but already someone else has asked what size speakers fit in our cars so I am suggesting a sticky. Mainly this would explain what types of speaker setups came stock so we hopefully don't have to keep asking about the differences between the 4, 6, and 8 speaker setups. The other biggy would be to answer not only what size speakers came stock in each setup but what size speakers we commonly replace them with.

I myself had to do a bit of digging to awhile back to pull up a thread about the rear speaker size and also the 4 inch speakers in the premium doors so I figure why not save someone else thje trouble down the road?
