Product Description
The 1970-72 Oldsmobile Cutlass is a popular A-body for restorations and cruisers. This Custom Autosound USA-230 is the 1970-72 Cutlass version, made to keep a classic look in the dash while adding modern features.
Fit and Ordering
This listing is the 1970-72 Cutlass version of the USA-230, made for the factory radio opening. Confirm fit for your model before ordering.
What Makes It Different
The USA-230 shares its look with Custom Autosound's USA-630, but it skips USB and CD changer control. What you get is a clean, dependable AM/FM stereo with presets, a clock and an auxiliary input for your own music, at a lower cost than the more feature-packed models.
Keeping the Dash Original
The dash is one of the first things people notice in a classic. A radio built to fit the factory opening keeps it looking right, protects the value of the car and avoids permanent changes, while still giving you the convenience of modern sources.
Feature List
- 4-way fader
- 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
Complete Your Order
- Front dual voice coil speaker, which plays both stereo channels through a single dash speaker
- Rear 6x9 speaker pair, Custom Autosound or upgraded Pioneer
- Kick panels with speakers, without speakers or with a Pioneer upgrade
- Hideaway antenna
Connect Your Phone
The rear 1/8-inch aux input carries music, podcasts and navigation prompts from your phone to the car's speakers.
Warranty
Every Custom Autosound radio we sell comes with a 2-year warranty.
Getting the Best Sound
Start with fresh speakers and good wiring. Old paper cones and corroded connections hold back even a great radio. Set the bass and treble modestly at first, then adjust for your cabin; open cars and trucks usually need a little more bass than closed coupes and sedans.
Before You Install
Before ordering, confirm your vehicle is 12-volt negative ground, which is what this radio needs. Custom Autosound makes an NGVB-HC booster for 6-volt negative ground systems and a PGPI-HC inverter for positive ground systems.
Disconnect the battery before you start, check the old wiring behind the dash for brittle insulation and use a fused feed with a solid chassis ground. A qualified auto sound shop can handle the job if you prefer. Vintage Car Radio sells the radio and accessories but does not offer installation.
Fit Questions
Dashes changed often, even within a model line. If you are unsure which version you need, have your year, model and any dash changes ready when you contact us.

Use the rear RCA AUX for a wired player. Pre-outs support adding an amplifier later without replacing the radio.
Suggested order for a 1970-1972 Cutlass
- 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 1970-1972 Cutlass
- This radio is sold for the factory Cutlass opening used in 1970-1972 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.
