Does anyone add a second horn without an extra relay? I am thinking to add a low tone to give it a boost, can the circuit handle the amperage on 2 horns? Thanks!

 

Was looking into doing the same thing. A relay "should" be added with its own fuse as those Fiamm horns draw 5 amps each. Look at the stock horn wires, they are not the proper gauge for 10 amps of current nor is the horn switch. You may eventually burn out the horn switch. Also, the horns will not be as loud because they will not get the full 10 amps they require.

 

Just get yourself a WOLO air horn. Yoiu will need a relay with it, but they are really LOUD!

 

Do you have one? Where did you install it, did you hide it some where?

 

I like the sound of an air horn but it doesn't look good on my bike, I would consider if I own a deluxe. I will wire a relay then, not hard.

 

A friend has one. http://www.amazon.com/gp/product/B00...d_i=B000F5DQWY

You might need some sort of install kit too. I'll find out.

 

Yes, anything more than what your have stock will need a seperate dedicated circuit. Not that difficult of a procedure.

 

i was told you can replace the 90db stock horn with one from napa that fits the harley housing and is 134db and under $40.

I already have the Fiamm freeway blaster under my cowbell, it is much louder than stock but I want to get more, an additional low tone will do.
