<VV> Speakers for LM

[DTerry8123 at aol.com]

I did this several years ago. I took two 4X6 in. , 4 ohm speakers, wired in 
 series. I used good quality high efficiency car speakers and mounted them  
on a piece of fiber board that is the same size as the original 6X9 
speaker.  Then  I glued a block of wood to the assembly to act as the magnet  
structure for the bracket that holds the speaker up to the dash. I did the same  
thing for the original rear speaker. It sounds the same as the original  
speakers, No better or worse with my stock AM/FM radio. With the rear speaker,  
you need to find speakers that are not too deep, or you will have problems 
with  the grille and the package depth. 
Or, if you have the original speakers, they can be re-coned.

A long  time ago I thought about mounting two small 4 ohm speakers, wired 
in  series in the stock location.  I never did it but it would present  
roughly 8 ohm impedance to the radio and depending on the speaker  
selection, could sound pretty good.  One challenge would be finding  high 
efficiency 4 ohm drivers, that won't break the bank. You could also  use 
an impedance matching transformer.  I think Hammond makes some  that 
would work great and are fairly inexpensive.
