An interesting site.
The first one, Model 200 sounds bad. It sounds like an electric shaver about to grenade.
The second one, Model 225-2T sounds better, more car like.

I like my stock horn. It sounds OK and I really don't use it much.
A wedding was the last time I remember using it. Oh and calling for the kids when I go and pick them up.
Sometimes my wife uses it when she leaves to toot goodbye.

If someone pisses me off on the road, I will either pass them or run them over.

haha yeah, i don't use mine much, mostly just some days after school something like 20 kids will all lay on the horn and beep them for like 15 minutes while in the line of traffic waiting to get out of the school lot. pisses off the administrators like nobody'* business

very simple..... 5 plastic clips underneath, 2 bolts, 2nuts......Ill try to get the pic for ya!

Verrry nicely done with that Galls siren speaker. In my oldsmobile cutlass ciera (RIP) I installed a 50 watt powerhorn and hooked it up to my Cobra CB radio, so I used it as a very loud PA. Man that thing was fun... along with Galls wig-wag headlight system wired to high-beams... =D One night we almost made a friend'* cousin sh** his pants when they were lighting firecrackers in people'* mailboxes.
