Does anyone know if you can buy some sort of a plate with cutouts for two smaller speakers that will fit in place of the single larger speaker in the dash?

 

i just saw jamies 66 build pics. he has two small speakers in the dash. last page

cut your own out of 1/4" fiber board

 

I might be misunderstanding your question.

If you are trying to put two speakers in the dash most supply places carry a dual speaker that fits into the factory hole. My stereo required 4 speakers to work properly so I got one of these for about $50.

If you are trying to upgrade to much better speakers these might not be the answer.

 

Get the CustomAutoSound 4x10 with the dual voice coils and dual tweeters. Fits the dash opening and works pretty darn well. Sounds much better than a pair of 4" drivers alone.

 

i dont recommend ANY Custom Autosound stuff.Its junk,pure and simple. Make your own plate and buy some 3.5" Kickers or MB Quarts. I can get those pretty cheap.
