Could be, get a multimeter and start checking You'll need a friend to hit the horn though. If all wiring and grounds look good, maybe a bad relay?

Also, by solid wire, I'm assuming it's also coated and not just bare wire, right?

Hey, not to be a jerk, or hate on anybody, but in the original write up, you meant 14 ga. when you said 14G, right?

I figured it out, the copper wire was so hard that the vampire clips did not make a connection... thanks for the help though

Nice write-up.

A few other questions though.

The Supertones I got have the mounting bars already installed on the horns. Per the instructions, they say that there is supposed to be a 2.7mm hole in the bar to mount the horns, however the ones I got have 10mm holes - the same size as the other end where the horn itself is mounted to the bar.

Do the horns have to be mounted directly behind the grille? I ask because if I don't want them to be seen, I would rather mount them behind the bumper beam as is the one factory horn. Do I want these nice big red horns to be seen? Maybe.

Per the instructions, and this also make sense, you can opt to wire the Supertones in place of the factory horns or you can add a switch inside the cabin and effectively switch between the factory horns and the Supertones.

Anywho, I'll take any comments / suggestions, b/c I have to wait a few more months to do any such work.

Thanks much.

You can mount them wherever you want. They're loud as hell, so it doesn't really matter.

Yup, just use the wire that you'd splice into the factory horns for the switched wire.

i painted mine flat black and have them mounted behind the grille looking out. i didn't want to red to stick out.... now after 88,000 miles, 2 and a half years, they are actually black with red specs, but you get the idea.

I've had mine in for a long time, but no relay. Guess I should do that.

Hi, sorry to keep this thread alive but I have some quick questions:

From my experience the Hella Supertones are _highly_ directional. And it seems that the desired effect from a Supertone installation is maximizing the loudness delivered to the intended recipient. Then wouldn't the most important consideration in the installation be to minimize the loss between the highly directional horn drivers and the intended recipient by avoiding reflection and mitigating obstructions that absorb sound?? And by that I mean installing the horns in a location that the overwhelming majority of the sound reaches the recipient by means of a direct path (ie: grille install, not in the bumper).

Exactly why and in what respect does using the supplied Hella (fog light?) relay make a difference? I am utilizing the stock Mitsuba RC-5001 relay and I am not experiencing a significant change in voltage drop across the horn after it is actuated. And the stock wiring insulation and relay are not overheating, even after extended use (alarm). If anything I would think the stock wiring would add the most resistance to the circuit, maybe a couple ohms at most; and the relay can't possibly be contributing more than 100mOhm of contact resistance. Keeping in mind that these horns are only pulling 72W after all..

Has anyone experienced a relay melted shut from overloading? Or stock wires fuming or connectors melting? Has anyone performed dB measurements for Supertones using the stock relay, for comparison's sake?

just found this thread and just picked up a set of supertones for my 05. quick question, when you mount the supertones themselves with the attached metal piece, do they stick out almost next to the grill? reason i ask is because i did a "dry run" fitting them up to see what it would look like and they sat real close to the grill

lemme know soon!

Yes, they'll be really close to the grill.

installed mine today. took way longer than i want to admint but everything came out perfect. used the relay which was also wired to a switch (power on/off to the hellas) inside the cabin. i suggest doing this in case you still want to make 'friendly' beeps with just the 2 OEM horns. but for 'jerk' beeps, flip the switch and OEM + Hellas are used when honking.

i'm glad i read this thread to find out about the 'dielectric grease'. i didn't know the name of it before. gonna put it on the relay connections.

FYI, here's the install instructions from Griot's Garage (where I bought my Supertones from).

http://www.griotsgarage.com/pdfs/77573.pdf

Page 2 shows the relay wiring diagram. I need to hook it up, one of these days, in both of our cars.

They don't mention a fuse, though....?...

i think the fuse is just for safety. if something happens with the horn and blows the fuse, then only the hellas lose power.

I'm planning on installing mine in the same way as you did yours though I'm a wiring noob. Do have any write ups on how to install the switch? Can this switch be had at Radio Shack as well?

i don't have a write up. installing the switch was my first time also. first i just installed the supertones with the relay. i think the directions posted recently in this thread are ok. installed it so that the original horns are also still hooked up. it's easy to hook up the switch afterwards. basically, instead of having the power wire go from the battery to the relay, it would go to the switch. then another wire from the switch goes back to the relay. the wires went through the grommit right behind the intercooler. i got the switch from kragen (http://www.partsamerica.com/ProductL...rsal+-+Rocker). however, the one i got that 'looked' like it would fit in one of the 'blank' switch spots, didn't fit well at all. i ended up jamming it in and a small part of the top broke off. now my switch is stuck permanently but it didn't look too bad. i think you want a generic switch for import cars.

I understand the thoughts behind putting the hella's on a switch, but when your going to need them you won't have the time to throw a switch!!
