Product Description
Custom Autosound 1970-74 Barracuda USA-630 In Dash AM/FM
NOTE: If your Mopar dash matches the Custom Autosound application for the 1970-74 Barracuda, the USA-630 is the workhorse in-dash choice. If the opening is different, ask about a Secretaudio SST hideaway system before you buy. Call 844-802-4499 with photos of the dash opening when you are unsure.
The Custom Autosound USA-630 brings AM/FM digital tuning, USB playback, auxiliary input, and strong four-channel output into a classic face sized for the 1970-74 Barracuda radio opening. Restorers who want modern features without paying for built-in Bluetooth yet standardize on the USA-630; Bluetooth can be added later with the BluKit accessory from the product options, and a single-disc CD player remains available as an add-on.
Why year-banded pages matter
Shoppers search for 1970-74 Barracuda radios, not generic “Mopar” catch-alls. This listing keeps years in the title and URL so the page matches that intent, the same way sibling Charger and Road Runner USA radios are organized on this site. Confirm your car’s year before checkout; badge packages and prior radio cutouts can change how the face seats in the dash.
Feature set
Expect electronic tuning and volume, USB for flash-drive music, rear auxiliary input, four-channel RCA pre-outs, separate bass and treble, fader and balance, digital clock, and a power antenna lead. The goal is a radio that looks at home in a Barracuda while sounding clearer than a tired factory mono unit on every drive.
E-body Barracuda and Cuda
1970–1974 Barracuda and Cuda models share the E-body platform with Challenger. This USA-630 listing expands the earlier single-year 1970 Barracuda radio into the full E-body band shoppers actually search, with the same Custom Autosound feature set and options.
Dash check still matters
Even within 1970–1974, prior radio work and factory air can change how the face seats. Select Factory Air correctly and call 844-802-4499 if you want a second set of eyes on photos of the opening.

Suggested order for a 1970-74 Barracuda
- 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 1970-74 Barracuda
- This radio is sold for the factory Barracuda opening used in 1970-74 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.
