Found 6.5 speakers that fit door without mods

Dash speakers are easy. There is a post on how to use your old speakers as the mount for the new speakers. It works really well and you get a good sound improvement with better quality speakers. Speakers behind your head also help to provide better distribution of sound although I found that with a std 4 channel head units that you have to couple them to either the door or dash speakers and their volume then becomes too low to be really effective. I'm still looking for a control I can put in to balance the volume.
