Product Description
Opel was a hidden gem of the sports car world, and the Opel GT, with its compact size and distinctive styling, is still a favorite. This KHE-300 by Ken Harrison is the Opel version, custom designed to fit the factory dash.
Fit and Ordering
Our listing identifies this KHE-300 as the Opel version. Contact us with your model and 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.

Small Car, Strong Sound
Small cabins don't need a huge system to sound good. The KHE-300's 50 watts per channel and separate bass and treble are plenty to fill an Opel, and Bluetooth keeps cables out of a tight interior.
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.
Room to Grow
The RCA pre-outs let you add an amplifier and subwoofer later without replacing the radio. Start with the radio and fresh speakers, then add power if you want more.
