Puma Deafeners now have electronic speedos.

Anyone out there have a circuit diagram for a speed sensing audio circuit that can be tapped into the radio or speaker circuits; ie speed up volume up, speed down volume down?

The LH manual one gets to be a little annoying in traffic

Thinks the speaker and sub-woofer circuits would be easiest. Set Radio high then use a volume control on a little black box.
