I purchased my pre-owned 2013 Honda Fit sport about two weeks ago and the first thing I noticed was the wimpy horn. A few days later, I purchased the 09 Accord horn per the handful of posts on here. I was hoping that the Accord horn would be suffice, but it actually sounded muffled and I could not hear it on the freeway with the radio on. If I couldn't hear it with my windows up and radio on (plus being only approximately 4 feet away from it), what makes you think the bonehead that's about to cut you off yapping away on his cell phone will hear it? I figured, this is not acceptable so I did some research and came across the PIAA Sport Horns. They come in two different tones - 500/600 Hz, which is a higher-pitched European sound and 400/500 Hz, which is more of an "American" sounding horn (e.g. Cadillac, Dodge, etc.). I opted for the 500/600 since it suits the Fit better.

My first priority was ease of installation. I am, by far, the most electrical-illiterate person out there, so running a bunch of wires to and from the battery with fuses and relays was out. The beauty with the PIAA's is that using a relay is optional. Obviously, I chose not to.

I installed the PIAA horns tonight and it took me about 30 minutes total from start to finish using this diagram I found online (pictured on the right):



The kit itself comes with the horns and two ground wires (one per each horn). The included instructions are pretty helpful also, but the diagram above should help you out for the Fit.

Take a trip to your local Radio Shack and show him/her the diagram. All you basically need are some splice connectors (pictured as vampire connectors in diagram), 1/4" female blade connectors and 16 AWG wire. I used 18 AWG and it was more than enough. You will end up spending about $10-$12 at Radio Shack. Follow the diagram (NOTE: You do not need to follow the ground wire portion as this kit comes with it's own ground wires) and you are done. I bolted the horns in an upside-down "V" configuration in the stock horn spot without any issues. Just be sure to give enough slack when making your positive (+) wiring and you should be good. The ground wires will not fit around the stock ground bolt location, so I used one of the two bolts just to the left of the mounting position (the ones with the Torx screws).

I was baffled as to how easy this was to install and the sound this puts out. You will, with no doubt, get someone's attention with these horns. For the mechanically inclined, the Hella and Wolo Bad Boy horns will do just fine, but for us less inclined, these are the real deal and are up there in terms of dB with the Hella and Wolo Bad Boy.

 

I like what I see

 

What was the source & pricing on the horns? Thanks for your assistance and have a good day!

 

I did the non-relay route with my hella supertones on my cx-5. I'm going to do the same for my Fit. Do you think the horns sound different between using a relay and non-relay?

 

Amazon...came out to about $49 shipped.

 

Nice modification and a good idea.

 

With the PIAA's, I don't think so. I think the relay option is just so you don't fry the OEM wire, but the horns don't draw enough power to do that. In fact, the PIAA instructions that came with the horns don't even specify to use a relay. The people that have installed the PIAA's used a relay as a precaution.

Now as for the Hella's, I wouldn't be able to tell you.
