One concern would be the current draw from running 3 horns in parallel. This is all on a 10A fuse, iirc. Since you already have it installed, I'd recommend a good long horn blast (maybe 5-6 seconds) just to make sure. If the fuse handles that you're probably ok.BlueMapleLeaf wrote:Cool, thanks! I decided to take upon myself to do it this long Canadian Thanksgiving weekend. I found a perfect spot for the 2-tone horns, facing front, attached to the top crossbar, using a T bracket and each horn's tab, forming a sideways " H ". I will post some photos. An image is worth a thousand words!
I'm planning to add the horns to the stock one, by splitting the wires as follows (blue wires are the Nissan original which I then split 3-way, represented by the orange wiring, to connect all 3 horns):
I would not increase the fuse size without making sure that wire size or electronic switching/power distribution modules are not limiting factors. We have experience with dual horns being OK on the 10-ampere circuit, but the OEM horn may add too much.BlueMapleLeaf wrote:Good point. But If it's indeed too much, I suppose the fuse will blow, and then what would be a solution? Replace the fuse with a 15A or 20A one?
That is what I recommend in this DIY. The stock horn is not in tune with the new horns anyway.powersurge wrote:Considering the stock horn is anemic to begin with, why don't you just pull the wire off on it, and use the 2 new horns? That way you don't have to worry about overloading the circuit.
If you try to lock the door with the remote control, it uses analog horn. The synthetic tone is only when u lock/unlock the door via the door handle.OrientExpress wrote:One note: On my 2018 SL the door locking acknowledgement is a synthetic tone not a beep from the analog horn.powersurge wrote:Considering the stock horn is anemic to begin with, why don't you just pull the wire off on it, and use the 2 new horns?

I replaced the stock horn with Hella horn sharp horn over the past weekend.BlueMapleLeaf wrote:Honked for a period of 6-7 seconds and still working. Sounded solid and the fuse held up fine. My only beef is the awful sounding (very low, muffled and anemic) remote door lock beep/honk/ confirmation. Again, I suspect the locking process does not provide or trigger enough power for a proper honk of 3 horns. Plenty for a quick chirp of the crappy OEM horn, but not enough for an additional double horn. I haven't tried disconnecting the new ones and see what happens. It would be very easy and quick. I will do so when I have a chance. In any case, for safety, I'd much rather have a decent horn than a louder door lock confirmation!
