Image #1: It is much easier to remove and install a radio or stereo with the glove box and glove box door removed.

Image #2: The Retrosound Radio Mod el One P/N 38-223 for the 1956 includes everything to mount the radio in the stock dash opening. The volume and tuner switches plug into the main body of the stereo. If you want to be creative and you are doing a custom dash, the switches can easily be relocated to the glove box or extend the wires and install them in a custom console.

Image #3: The volume and tuner switches are held to the stereo's main body with elbow brackets. Install the rectangular plate onto the volume and tuner switches. #3c The places fit on the back side of the elbow brackets. Next feed switch through the elbow bracket and using the locking washer, flat washer and nut, anchor the switch to the elbow bracket. The bracket allows the switch to mount in various locations for different applications On 1955-57 cars the switch mounts in the outermost location.

Image #4: The stereo includes a face plate to match the Bel Air dash trim for your particular year car.

Image #5: Install another nut and flat washer on the switch stems. These nuts will be used to adjust the depth of the stereo in the dash. The elbow brackets are held to the main body of the stereo with cwo machine screws. The jacks from the volume and tuner switches plug into the side connectors on the radio. With the switches in place, install the face plate and adjust the nuts on the volume and tuner switches so that the face of the radio is flush with the face plate.

Image #6: On the back of the stereo you will find the female port for the antenna.

Image #7: A stud and nut is supp lied to attach the rear mounting bracket. Once the radio is installed, the mounting bracket may be attached to the inner cowl (or speaker grille stud on 57 cars) to support the back of the stereo.

Image #8: The volume and tuner shafts are attached to the dash with another nut and flat washer. Once the radio is in place, the year specific knobs may be installed.

Image #9: There are two male jacks that plug into the single female jack on the radio. The red is the "power wire" and needs to be connected to a key-on 12-volt power source. The black wire is the "ground wire" and needs to be connected to the body. The yellow wire is the "memory wire" for the station memory. This wire needs to be connected to a constant 12-volt source.

Image #10: The blue wire with the white tracer is the "power wire for a power antenna". This wire would connect to the power source wire for a power antenna.

Image #11: The remainder of the wires are for the front and rear speakers, with each wire clearly marked for its function.

Image #12: The front speaker on 1955 and '56 cars mounts on the right hand side of the dash behind the speaker grille. On 1957s, the front speaker is in the center of the dash, under the speaker grille.

Image #13: The Restosound speaker PIN 38-226 is a 6x9" 3-way speaker with dual voice coils and will give you great stereo sound. This speaker features a super-slim 1-3/4" mounting depth for easy installation in tight spots and includes neodymium magnets that are 4X more powerful than standard speaker magnets. It is wired to give you true stereo sound out of just one speaker assembly. This speaker mounts directly to the stock 1955-56 speaker bracket once the center "grille" of the original bracket is trimmed away.

Image #14: If the stock '55-'56 speaker bracket is among the missing or if your car was never equipped with a radio, a replacement bracket PIN 38-50 is available. Th is bracket mounts to the dash using the stock mounting holes and unlike an original bracket, does not require modification.

Image #15: The elbow brackets attach to the top of the speaker bracket with supplied hardware at a slight angle to match up the dash. The speaker is held to the speaker bracket with four screws and nuts supplied with the speaker.

Image #16: The 1955 and '56 speakers use a rubber speaker boot PIN 06-28 to channel the sound through the dash speaker grille. The boot slides down onto the upper arms of the speaker bracket.

Image #17: The upper speaker bracket arms attach to the inner two holes behind the speaker grille using the supplied machine screws and nuts. The lower lip of the bracket attaches to the lower lip of the dashboard using the supplied machine screws and nuts. With the speaker installed, connect the appropriate wires from the stereo.

Image #18: Now to put some real sound in your car, Retrosound also makes 6" X 9" rear deck speakers PIN 38-227 that can be mounted in the package tray These speakers have a chrome body and a molded plastic grille with flames. This speaker is especially designed for use in classic cars and looks like it! The bezel can be left black or painted the interior color.

Image #19: Original cars only had a provision for a single rear speaker on the driver's side. Using a jigsaw,o pen up the factory hole to an oval and cut an oval hole in the package shelf in the corresponding location on the passenger side. Using the speaker as a guide, drill four 3/16" holes for the mounting screws as required o n the passenger side. Also trim your cardboard package tray to match the holes in the steel shelf. The speakers themselves mount to the bottom side of the steel package shelf. Feed the mounting screws down from the top throug h the speaker bezel, package tray, package she lf and speaker. Next install the nuts on the screws and tighten . Complete the wiring to the rear speakers and you now have a new top-quality and highly adap table sound system for your classic!
