Front speaker size

Post by 471Magnum » Sat Mar 29, 2008 5:57 pm

What is the front speaker size on a '71? 4x10?

Anybody ever jimmy a couple of 3 1/2's in that opening? I've done it on '68-'70s by making an adaptor plate. Wondering if I could do the same on a '71.

Hey 471Magnum,

I have plans of doing the same thing, making an adapter for two 3½" units in the dash.

I have seen an aluminium adapter made for 72-74 chargers on the net, don't recall where though!

Only hazzle as I see it, could be that the magnets could interrupt with the vent-channels inside the dash!?
