PIAA Sports Horn

I came across these today and was wondering if they are new? I can't seem to find the current draw for them, so wonder whether a relay, etc. would be necessary or if they could just be a plug and play installation. What do you think?

The website has a phone number, give them a jingle and ask.
As for plug-n-play, I doubt it would be wise given the poor wire job Yamaha did. I'd use a relay to install it. I bet that if you put a higher current horn (most likely) onto the 18 AWG wire that could be anywhere from mildly to severely corroded, you can watch the entire electrical system dim every time you hit the horn.

 

I found this on the PIAA web-site:

The PIAA Sports Horn, a two-tone system, differs from most of today’s factory horns, which are single-tone. One PIAA horn has a sound frequency of 400Hz; the other is 500Hz. The two tones combine to produce an attention-getting 115dB of sound. Each horn attaches easily with a single mounting screw and the dual unit takes power from the vehicle’s existing horn. Combined current draw is 5.4A.

Does anyone know what the current draw is for the stock set of horns?

 

Those sounded a little weak. I have a small form air horn on the bike in replacement for th disks that went south. I can use it to call my son home from across the neighborhood. Tapped it at my wife on the road and she said she thought a semi was next to her (and I only tapped it). Moves cars back into there lane better than anything else I have found. Only issue was I had to mock up my own mounting system and it did require a relay.

 

Here's some info I found on the Stebel air horn:

Technical specifications:
Sound Output: 139 dB
Operating Voltage: 12 Volts
Absorbed Current: less than 18A
Fundamental Frequency: 530 Hz & 680 Hz

I also looked in my Haynes manual and from what I can figure out (and the print is reeeeeeally small...) the stock horn is on the turn signal circuit and that uses a 10A fuse.

I had been looking at the air horns, but when I found these PIAAs I thought I might be able to get louder horns than stock that did not require re-wiring.

 

The wiring on the airhorn was really simple. The original wires to one of the horns goes to the relay. The power comes from the battery through one of the extra spaces on my new fuse block, then right up under the tank with the rest of the wiring. It then hits the relay which I mounted to the bar under the tank. It then goes to the horn and from there ground. It is currently not the prettiest mount, but this summer when I have time (teacher, yea summers) I will redo the mount to hide the horn more. It works, is really loud and is easy to do. You can usually get a "kit" with the horn that will have the heavier gauge wire, connectors, etc. you need. If you don't have some laying around like I did. I have had no problems with the "extra draw" on the system, It is not a constant draw, but temporary and the battery handles it no problem!
