In the 1950's certain European cars had a selector switch that allowed one to use a friendly "city horn" that was a little more considerate for pedestrians and parking lots.

That said, the very few times I've used the 928 horns, they proved woefully inadequate. I put in the Bad Boy horns but they aren't that big an improvement. Having them inside the enclosed wheelhouse muffles the sound significantly.

Meanwhile, the quoted Cali sound standards mention a 200' "audible" distance, but make no mention of the distance at which the 110 dB(a) limit is determined. So long as they are consistent with the 200' measuring distance, no worries. Reality: I no longer live in the Great and Socialist Republik of California, although I do drive there. Plus, if the horn is used as intended (not in crosswalks...), I'd rather discuss the horn sound with the judge than argue the accident repair costs. Plus, that "city horn" switch would easily and instantly validate the "who, me?" claim for the officer. It's all hidden from view in the wheelhouse area, right?

Scheissco developed this technology years ago. I'm calling my lawyers.

Use a Sheissco lawyer, and we have nothing to worry about.

True. I installed 2 of the Bad Boys in the 928 also, which makes the volume decent

Yea, that is classy, Randy.

But useful for those abusers that park in fire lane right next to the supermarket entrance. Mount it on the passenger side for max effect, pull
s- l- o- w- l- y abreast of the guy sitting in the car while the "mrs" picks up her lisinopril and give 'em a blast. Good way to get shot around here.

Yeah considered doing a relay setup - would definitely deliver more amperage and be even louder - but using the original 12V wiring harness is still pretty frickin' loud and very easy to set up.
