    I'm gonna need one of those brackets. The air horns just aren't getting any attention these days.

    I have been cut off several times lately. Hit the horn and they just keep coming over.

    Time for some more umph in my horn.

    I didn't want to cut and splice the OEM horn wiring harness.... So through diligent "Realoem" searching.... I located the matching OEM plug for the horn connection... My plan is to drive a separate remote fused relay with the OEM horn circuit and power the Hella's with a higher amperage circuit....

    Looking at the stock wiring, there is no way the Hella's will get the power they require without this upgrade...:D

    The Hella horns are rated at 72 watts which works out to 6 amps at 12 volts....

    To be continued....

    The horn fuse in the R56 is rated at 20A, so shouldn't you be able to get by without the relay? Two 6A horns should not be a problem. I'm thinking of just replacing the stock horns with the Hellas. If I can find the stock horns.... if they will mount in the stock locations.....haven't looked yet.

    Others have stayed with the stock horn connections and spliced the oem wiring....
    I elected to use the stock connection to trigger the Hella relay and I also didn't want to cut and splice the oem horn plug so I can revert back to stock.... Once you see the size of the stock wiring you may question this as well..... I was nervous and upgraded to a heavier gauge wiring at the horn with a OEM plug...

    I'll say this.... The Hella horns put the stock to shame..... No way are they both consuming the same amperage....

    Not having looked at my horns yet, am I right in assuming they have a proprietary connector? As far as the wire gauge and circuitry, I checked the Hella website to make sure, and the Supertones are rated at 72W. (72W/12VD=6A) On a circuit rated for 20A the stock wiring is adequate for two 6A horns. If/when I replace them, I don't plan on going back to stock so changing connectors won't be an issue for me. Now, where the heck are the horns located and will I be able to access them without ramps or a lift? :confused5: :biggrin5:

    I think they can get by with smaller gauge wire because the time the circuit is energized is very short, relatively speaking.......you don't hit the horn and hold it for 5 minutes. You need the 20 fuse for the inrush current.....

    Thanks Metalman. Appreciate the info. You wouldn't have another of those nifty brackets lying around would you? :) Excellent work on those by the way.
