Audio System 69 Custom

Hi there,

I am fairly new to this forum and have a wonderful question for all of the Dart enthusiasts out there. I managed to get my grandmothers 69 Dart Custom (4 door) and want to put a decent audio system in for him. Does anyone have any advice for speakers? I am good with the radio but will take advice on that as well.

What I am looking for specifically is the rear deck speakers, did Dodge put any in the rear window?

Thanks for the advice!

p.s. I did check the service manual and it did mention rear speakers.
