When you're outfitting a classic car for a modern audio upgrade, two of the most popular plug-and-play radios from Custom Autosound are the USA-230 and the USA-630. Both preserve the vintage dash look, but each brings a different balance of features, cost, and capability. Here’s a breakdown of how they compare—and which one might be best for your ride.

1. Appearance & Fit
   Both radios are purpose-built to fit stock dash openings in specific car models, so no cutting or fabrication is required. Whether you've got a 1967 Mustang or a ’70s Chevelle, the bezel, knobs, and faceplate are designed to match factory styling—classic looks with modern internals.
   If keeping your dash looking as original as possible is your goal, you can’t go wrong with either.
   
   
2. Feature Set: Basic vs. Enhanced:
   
   USA-230: (about 200 W peak, 4×50)
   1. AM/FM stereo radio with electronic tuner and digital clock
   2. Auxiliary input (1/8″ jack via rear-panel RCA cable) for streaming iPods, phones, or satellite tuners
   3. 16 presets (12 FM / 4 AM) and a 4-way fader to balance front/rear sound
   4. Four-channel RCA pre-outs so you can still run amps or subwoofers later
   5. Great “value” option, especially if you don’t need USB, iPod dock control, or built-in Bluetooth
      
      USA-630 (up to 300 W peak)
      1. Full-featured AM/FM RDS tuner with digital readout (station name, song, artist info)
      2. USB port for flash drive MP3/WMA playback and charging, plus iPod dock and control built in
      3. Auxiliary inputs and compatibility with Custom Autosound BluKit add-on for Bluetooth streaming & hands-free calling
      4. Bigger amplifier section and more onboard flexibility; still offers RCA pre-outs for amps and subs
      5. Comes pre-assembled and ready to install—less fiddling and fewer surprises in the garage
         
         
3. Which One Should You Choose?
   
   If you're going for a straightforward, budget-friendly upgrade that leaves plenty of room to add amps, subs, or Bluetooth later, the USA-230 is a solid choice. It's got the core features you need—tuner, AUX input, RCA outputs—and preserves the vintage dash look without excess cost.
   
   If you already want digital music playback, streaming, phone integration, USB, and the potential to go all-in on audio without major add-ons, then the USA-630 is the more powerful, future-proof pick. You pay more, but you get more built-in features, and the install process is even easier.

Or modern convenience out of the box and fewer accessories? Either way, you're getting a radio that looks right, fits without cutting, and sounds great.
