Good day!

Does anyone know of any website or any literature that features how to install speakers for totally clueless people? With diagrams and step by step instructions?

I just purchased a 1989 300E, which had no head unit and speakers. I'm planning to get a head unit from Best Buy (installation is free, so I guess I'd rather have them install it.. I don't think I'd be able to do it, since this would be the first time to try)

Speakers for the front (4inch) and the rear (5.25) inch come with a cost of $35 for each pair to install so I was thinking of doing this myself.

Can anyone help me on this matter? Thanks!
