Product Description
Your 1956 Chevrolet Two-Ten is almost perfect, but the factory radio is AM only, if it works at all. Custom Autosound's USA-230 fits the dash with no cutting and gives you AM/FM stereo and an input for satellite radio or an iPod.
Fit and Ordering
This version is made for the 1956 Chevy 210 dash.
The Radio in Brief
Think of the USA-230 as the straightforward member of the Custom Autosound family. It looks like the USA-630 from the driver's seat, but instead of USB and CD changer control it keeps things simple: a stable electronic tuner, 16 presets, four channels of power and a rear auxiliary input.
Classic Look, Modern Function
An original radio may look great, but it rarely works well today and cannot play your own music. A modern radio made for the dash gives you dependable reception, presets and inputs for your devices without changing the period appearance of the interior.
Key Features
- Digital clock
- Power antenna lead
- AM/FM stereo with an electronic tuner
- 16 presets (12 FM and 4 AM)
- 200 watts (50 watts x 4)
- Rear RCA auxiliary input, with an RCA to 1/8" pin jack cable included
- 4-channel RCA pre-outs
- 4-way fader
Options on This Page
- Front dual voice coil speaker, which plays both stereo channels through a single dash speaker
- Rear 6x9 speaker pair, Custom Autosound or upgraded Pioneer
- Hideaway antenna
A Tri-Five Favorite
The USA-230 is a popular choice for Tri-Five Chevys because it keeps the dash looking right. Pair it with a dual voice coil dash speaker for stereo from the original speaker location.
Warranty
This Custom Autosound radio is covered by a 2-year warranty.
Planning Your System
Think about where speakers will go before you order. The dash location, kick panels and rear package shelf are common choices in classic vehicles. If you plan to add an amplifier later, the RCA pre-outs make that easy without changing the radio.
Installation Notes
The radio needs a 12-volt negative ground system. Many older vehicles were built 6-volt or positive ground, and Custom Autosound makes converters for both situations. Ask us if you are unsure what your vehicle has.
Take your time behind the dash: label the old wires, replace anything brittle, fuse the power lead and ground the radio to clean metal. If you are not comfortable with automotive wiring, have an auto radio specialist install it. Vintage Car Radio sells the radio and accessories but does not offer installation.
Amplifier Ready
The 4-channel RCA pre-outs make it easy to add an amplifier for more power or a subwoofer for deeper bass, without replacing the radio.
Choosing Speakers
Many classics have one dash speaker. A dual voice coil speaker carries both stereo channels from that location, and a rear 6x9 pair, Custom Autosound or upgraded Pioneer, fills in the back.

Suggested order for a 1956 Chevy
- Disconnect the vehicle battery before any wiring.
- Connect ground first, then constant (yellow) and ignition (red).
- Connect the antenna plug and the blue power-antenna lead if your car has a power antenna.
- Wire all four speakers, matching polarity.
- If using an amplifier, run RCA cables from the front/rear (and sub on USA-740/USA-850) pre-outs.
- Reconnect the battery and test radio, speakers, and charging system voltage.
Tech tips for 1956 Chevy
- This radio is sold for the factory Chevy opening used in 1956 models—do not cut a modern DIN rectangle if you want a stock look.
- A poor ground is the most common cause of whine or weak audio; scrape paint at the ground point and use a star washer.
- If AM reception is weak, check the antenna mast, cable continuity, and that the antenna plug is fully seated.
- Vintage Car Radio does not install radios. If you are not comfortable with 12V wiring, use a qualified installer.
