I'm back with my dual 3.5" speaker brackets

Although the brackets are cut with 3" holes, initially to accomodate 3.5" speakers in my son's Dart Sport, it appears that 4" speakers work just fine. Several of you have reported to me that you intend to use 4" versions (or have already), so I bought a pair of my own Volfenhag ZX 834-R 4" two-way speakers to use as a test.

As you can see below, they fit snuggly on my shortest bracket used in '64-'66 early A-bodies and '64-'69 B-bodies, but they do fit. Also, the speaker cones' rubber surrounds do not come in contact with the surface of the bracket. They even fit better on the longer brackets for '67-'74 A-bodies. This greatly increases your selection of available speakers to choose from. I can't "speak" for any other brands of speakers, but the 3.5" Volfenhags in Aaron's Dart Sport have served him faithfully for approximately 5 years without problems.

Here is a list of some of the speakers you guys are using:
Pioneer TS-G1043R 4", Kenwood KFC835C, ES3.5XV.2 The Powerbass Evolution, Legacy LS328, Kicker KS400 4", Rockford Fosgate P132 3.5", Polk Audio DXI 350, Volfenhag ZX 832-R
