Speakers!

[mobswing]

Hi everyone.

I need to replace all the door speakers. i have a couple of questions that I need help answered.

The first is what speaker size will fit comfortably into the gaps left by the old speakers without the need for expensive adaptors and fidgeting around.

The second is how many speakers are there in total and where are the rest of the speakers.

Lastly if i were to fit a sub woofer where is the most ideal place to place it in terms of safety and impact.
