Product Description
A vintage Porsche deserves a radio that suits its interior. This KHE-300 with Bluetooth by Ken Harrison is the 1956-1965 Porsche version, combining a period look with Bluetooth, USB and SD card playback.
Fit and Ordering
Our listing identifies this KHE-300 as the 1956-1965 Porsche version. Porsche dashes changed during those years, so contact us with your model and year before ordering to confirm fit.
Why This Model
The KHE-300 pairs old-school controls with new-school sources. Press a pushbutton for a favorite station, stream from your phone over Bluetooth, or load music onto a USB stick or mini SD card.
The Right Fit Matters
Vehicle-specific radios are designed around the dash they go into, so the controls line up and the face sits where the original did. That makes installation simpler and the finished result looks like it came from the factory.

Electrical Check
Some early Porsches were built with 6-volt systems. The KHE-300 needs 12-volt negative ground, so check your car before installing and contact us if it is still 6-volt.
Choosing Add-Ons
If you are not sure which speakers or antenna to choose, tell us about your vehicle and how you use it. A car that is mostly cruised around town needs a different setup than one driven long distances, and we are happy to help you match the parts.
Electrical and Installation
The KHE-300 requires a 12-volt negative ground electrical system. A 6-volt or positive ground vehicle will need a converter, so check your system before ordering.
Most installs go smoothly when the wiring is in good shape. Inspect it first, add a fuse to the power lead and test the radio on the bench before mounting it. An auto radio specialist can install it for you if needed. Vintage Car Radio sells the radio and accessories but does not offer installation.
Using the Presets
The six AM and six FM presets sit on extended pushbuttons that are easy to find by feel. Tune to a station, then press and hold a button to store it. Seek and auto scan help when you are traveling.
