For classic car owners with a DIN-sized dash opening, the Custom Autosound USA-4 DIN radio hits the sweet spot between preserving vintage aesthetics and integrating modern audio functions. Whether your dash was cut to a standard 7.2" × 2.1" DIN opening or you're building a street rod, this radio brings smart design and seamless fitment to the table.

1. Ready to Install in Most Stock DIN Openings: The USA-4 DIN is engineered to slip directly into virtually any “single-DIN” opening—whether that’s a newer classic car, foreign import, or a hot rod with a DIN-sized slot cut into the dash. That means zero cutting of the dash, no trimming of trim pieces, and no welding. For restorers and collectors, that level of reversibility is a major win.
   
   
2. Period Look, Modern Features: Under the hood, the USA-4 hides an impressive modern feature set:
   1. Flip-down digital display that preserves a classic radio face when closed.
   2. Built-in CD player with ESP (Electronic Shock Protection) to prevent skipping on bumpy drives.
   3. Front-panel USB port behind a hidden door and auxiliary input for connecting modern devices.
   4. Bluetooth streaming and hands-free calling, plus RDS-capable AM/FM tuning.
   5. In short: you get modern usability without a giant modern look.
      
      
3. Solid Power and Expandability: The USA-4 delivers four channels of amplification at 40 watts per channel, enough to power a solid speaker setup with clarity and authority. If you want more power or a subwoofer later, the unit includes RCA pre-outs to expand the system without needing to replace the radio.
   
   
4. Dual-Finish Options & Dash-Friendly Styling: The USA-4 comes in both black and chrome finishes, letting you match the classic car’s dash styling. The fold-down face panel stays flush when closed, retaining a clean and unobtrusive look that won’t distract from vintage gauges or trim.
   
   
5. Versatility Across Makes and Models: Although it was designed for vehicles with standard DIN slots, the USA-4 is versatile enough to be used in classic GM, Ford, Mopar, European imports, or custom hot rods. Because it conforms to the industry-standard dimension, it fits into many builds without needing custom fabrication.
