Product Description
Classic GMC trucks were built to work and are now loved as drivers and show trucks. This KHE-300-USB with Bluetooth by Ken Harrison is the GMC Truck version.
Fit and Ordering
Our listing identifies this KHE-300 as the GMC Truck version. Contact us with your year before ordering to confirm fit.
About the Radio
The KHE-300 is a Ken Harrison design that looks like a classic pushbutton radio from the driver's seat. Behind that look are Bluetooth streaming, a front USB port and a mini SD card reader, so you can play your own music without a modern stereo in the dash.
Why a Vehicle-Specific Radio
A universal stereo usually means cutting the dash or using an awkward bracket, and it rarely looks right in a classic. A radio made for your vehicle fits the original opening, keeps the knobs and face where they belong and can be removed later if you ever want to go back to the factory radio.

Truck Cab Listening
Truck cabs are noisy. The KHE-300's separate bass and treble help keep music clear, and Bluetooth keeps cables off the bench seat.
Speaker Tips
Good speakers make as much difference as the radio. Many classics have a single dash speaker location, which is where a dual voice coil speaker shines because it carries both stereo channels. Adding a rear pair and using the fader gives you full stereo that fills the cabin.
Getting It Installed
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.
Bench test the radio before final mounting, use a fused power source and make a clean ground connection. If you would rather not do the wiring yourself, an auto radio specialist can install it. Vintage Car Radio sells the radio and accessories but does not offer installation.
At Night
The blue illuminated LCD shows the clock or frequency and is easy to read after dark without being distracting.
Tone and Balance
Separate bass and treble controls let you shape the sound for your cabin, and the 4-way fader balances front and rear speakers.
