We are stocking the Supertone Horn Set. This is one of the loudest and most compact horn sets available. It comes with the two horns and a relay. One horn is 500 Hz, the other is 300 Hz and the sound level is a staggering 118dB.



We are selling these horns for $59.95 right now. If you are looking for a much louder and better sounding than stock horn then now is the time to jump on a set of these.

PRICE- $59.95

We accept paypal and credit cards for your convenience.

you got any sound clips to show the difference?

I've got them in my CRX; I'd guess 20-30% louder than W203 stock's horn.

What year is the CRX? Always loved that car man!!!

tommy

1990 Si; zc engine, i+h+e, Bisi cams, 4-pt rollbar; way too many parts cluttering up my apt for it. Hoping to get everything in it this spring, and hit a couple of local autoxes and Pocono/Limerock if I can.

It really is a very fun car. Hoping to get it on the road by the end of the week - been in winter hibernation since October.

Anyone actually get these and know how to install them on the w203?

I bought a set and it appears as though they are not plug and play at all - requiring extra wiring run to the battery?

Instructions also suggest not putting them anywhere that water can get into them - this doesnt make sense for our car as these are infront of the radiators...

Any input Tommy?

Most like the ones for the STIs are right in front behind the grill. I assume you just splice the wires to the factory horn wires and bypass the harness part.

TTT - staff@rpm - any help?

tommy

I didn't install mine, and the CRX is at the shop, getting some new stuff on it, otherwise, I'd look.
It'll be done probably by the end of the week.
I'll do a run through the Honda forums and see if I can find anything on point.

Interested, would like install information.

My middle finger is far more satisfying at getting attention on the road.

intrested in these if the posetr would answer the question on the water/splash proofability of these horns........you will need to run these doing a relay wiring ......you use the OEM harness signal to trip the relay and draw juice straight from the battery.......but if these are not water proof or atleast splash proof then they are virtually useless for our car application, cause the OEM horns are at a very good location and any deviatation from this would take away from the gains in db that you will achieve from these horns...i.e. installing it behind the radiator etc....

Here are the install instructions:

Comparison on a Subie RS, from YouTube:


Plenty of clips, though.

Javvy, I would be surprised if it weren't water proof, but can't see anything directly on point.

I got roots horn first time I went to India and man those things are LOUD!

Moviela

The horns are only 3 db louder than the stock horns, but they are pretty. You don't need the relay, or any tricky wiring. There is a relay and fuses in the front SAM for the fanfare horns that will handle the 5.5 Amps of these horns.

You might need to change the Fastons (connectors) to fit the new horns. Don't worry about the water. These are made the same way as the factory horns. The only warning about water concerns the mounting of the relay. (C class does not need the relay.) The relay terminals need to face down to be rain tight.

TruTaing

I installed these yesterday. The Fastons fit Snuggly - you can see that the fastons scrape the connections on the horns, but, unfortunately, I have no sound. Any ideas why this is not working?

Moviela - I saw the fanfare fuse, do i have to plug in a new 5.5amp fuse to make this work?

Thanks!

Moviela

The fuse in your car should be good enough. Probably 20A or so to do both horns.

Were your old horns working? Possibly the relay is kaput, or worse the horn pad contact that communicates over CANbus to the front SAM is having a problem through the device Mercedes calls a clock spring in the steering column.

Do check that the brown wires on the horns are actually connected to ground. Near zero ohms on a meter.

TruTaing

My horns use to make a whimpy sound as if the horns were busted and/or the horns were lacking the power to make noise at full volume.

Moviela

Time to get out the volt meter and measure the voltage at the horn terminals. If less than 12, measure the voltage from the brown wire to chassis, it should be near zero. Then measure the other horn wire to the battery (+) terminal. It should also be near zero. If either are not near zero, you need to service that circuit connected the wire that failed.
