Hi. Well my father-in-law and I am restoring a 1946 plymouth 2dr sedan delux (well he is restoring it i'm just doing the elctronics and such) we have found a place that took the factory radio and turned the guts into a new am/fm radio with 4 speaker hookups (it turned out really cool
; looks completly stock, and even has an aux input for an ipod under the dash). This car only had 1 speaker in the center of the dash and we want to change this to a 4 speker set up. There is very little room behind the rear seat and I am looking for any ideas on size and brand of a speaker that sounds great on a 40watt/ch stereo radio
. More than likley anything above 5-1/2" is too big.
