Surface-mount modules for 4" or 4"x6" speakers
Our take on the RetroSound RPOD4 by Crutchfield's Dave Delamere
Where no speaker has gone before
You've got a classic vehicle that needs some music in it, but your vehicle didn't include factory speaker locations, and there's no room behind the factory panels for installing new speakers. Enter Retrosound's RetroPod modules.
The RetroPod RPOD4 surface-mount module lets you choose the locations for new speakers in your vehicle. Mount the two modules on your kick panels, doors, rear deck, or any suitable flat surface, then run some speaker wire to your car stereo or amplifier. You can then install your choice of 4" or 4"x6" speakers in the RPOD4 modules.
Customize your application
You can paint or carpet the ABS plastic modules to match your interior. The modules also include mesh grilles to complete the installation.
Installation note: Using the template that Retrosound provides in the modules, you'll need to cut and file the mounting hole in the modules for the speakers you install. You'll also need to drill mounting holes for screws that secure the speakers. You'll want to consider professional installation if you don't have the proper tools.
RetroSound RPOD4 Reviews
What's in the box?
- 2 RetroPod modules
- 2 Grilles
Overview: RetroSound's R-POD4 surface-mount modules offer an easy way to add speakers in non-factory locations. They are mounted using screws (not included) to secure four tabs on the under side of the module to a flat surface (approximately 7" x 10" minimum) in the vehicle.
Installation: You will need to cut out the speaker mounting holes in the plastic R-POD4. Two lines are scored on the speaker mounting surface, designed for 4" and 4x6 speakers (3.6" diameter and 3.6" x 5.6" oval respectively, be sure to measure your specific speakers before cutting). Because the R-POD is angled (approximately 10°), the exact allowable mounting depth varies with size and shape of the speaker basket. The depth is 1-3/4 inches at the center of the opening, so the allowable depth of a typical speaker is approximately 1-1/2". Using the included grilles, there is approximately 5/8 of an inch allowable mounting height and the frame measurements of the speakers should not exceed 4-5/8" x 7-1/2". Once the hole is cut for the speaker, the four tabs for mounting the R-POD are accessible through the opening.
Compatibility: RetroSound recommends using their R-452N or R-463N speakers with the R-POD4, but other brand speakers can also be used.
