I'm placing an aftermarket radio in my '68 coupe and I'm also planning to upgrade the rear speakers.
My dilemma comes from trying to find a pair of modern technology 6x9 speakers that don't have space age looking grills. I can't believe how difficult this is becoming. Nearly all the speaker grills I've come across look like some sort of Tranformer character.
I recently saw a pair of plain black Pioneer speakers in the NPD catalog, but at a price of $124 (page 23 of the '09 catalog). I'm sure these speakers must go for less elsewhere.
Anyone else come up with a solution?
