Fitting twin electric horns - help needed!

[Brendonian]

I got carried away with my little winter maintenance job of cleaning inside the front intakes, and decided to upgrade the utterly pants horn. 
I bought the twin electric horn kit from Eliseparts, and it doesn’t come with any instructions. Should be an easy job, but when trying to remove the original horn, I stupidly started slacking off the bolt that fixes the mounting bracket to the crash structure. It just keeps turning, so I guess there’s a nut on the other end. Anybody know how to access it? I’m guessing it’s either behind the wheel arch liner, or I’ll need to remove the front undertray?

Looks like a nut on the other side...

Worth a read of this re current draw of your new horn too, just in case...

Thanks Bibs. I managed to tighten than bolt up, so no longer any panic about how to access the nut.

Eliseparts actually say they provide a bigger fuse with the horn pair, though it was missing with mine. I'll check the current draw, and consider switching to those PIAA horns if it's too much for the wiring 👍

Hi @Brendonian, I installed the twin PIAA horns a couple of years ago. Have had no problems with the existing wiring current load and still use the same fuse. I just needed a long bolt and spacer to mount the horns to the original bracket.

Thanks @Mark.A  That’s reassuring 👍

Ok, tested the Eliseparts horns tonight. My digital ammeter only officially reads up to 10A, but it shot up to 13A, so I'm officially scrapping these. PIAA Superior BASS horns ordered!

New PIAA horns arrived today. I’ve done a test fit, and I’m happy with the sound. Don’t like the ugly connectors that came with the Eliseparts kit, and the wires are stupidly long. The PIAA kit only comes with wires to connect one horn, which they suggest splicing into the car’s harness. Don’t want to permanently modify the car’s wiring, so I’ve ordered a nicer set of connectors and a crimping tool. I’ll make my own harness adapter to finish the job properly. 

Also looks like my ventilation system could be improved by clearing some of the adhesive from the intakes 😂
