Product Description
Graham cars, built in the 1930s, are rare today and known for their distinctive styling. This KHE-300-USB with Bluetooth by Ken Harrison is the Graham version, made to keep a classic look in the dash while adding modern features.
Fit and Ordering
Our listing identifies this KHE-300 as the Graham version. Contact us with your year before ordering to confirm fit.
The Radio in Brief
With 50 watts per channel, a PLL tuner and Bluetooth, the KHE-300 is a capable radio wrapped in a vintage-style face. It plays music from a phone, a USB stick or an SD card, and the RCA pre-outs let you add an amplifier later.
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
- 6 AM and 6 FM presets on extended pushbuttons
- Manual up/down tuning, seek and auto scan

- 200 watts of output (50 watts x 4)

Listening Your Way
Use the PLL tuner for local stations, then switch to Bluetooth, front USB or the mini SD card reader for your own music.
Electrical Check
Some Graham models were built with 6-volt or positive ground systems. The KHE-300 needs 12-volt negative ground, so check your car before installing and contact us if it has not been converted.
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
Like other modern radios, the KHE-300 runs on 12-volt negative ground. Contact us if your vehicle has a 6-volt or positive ground system.
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.
