How to install a aftermarket horn in a 4th gen. - Honda Prelude Forum

:Prefix:
The other day while beeping my horn for my wife to open the garage door I noticed my horns sounded like wounded goose. It was all irradic and low pitched.

After researching the issue it looks like one of my horns had **** the bed. ( 4th gens have 2 horns )

So I went to my local autoparts store and asked the guy for the smallest loudest horn he had. He proceeded to give me a 132 decible truck horn ( this mofo is freaking loud )

Preparation: get your tools and parts together. You'll need:
1. Replacment horn
2. Metal mounting bracket
3. 10mm nut
4. 10mm ratchet or open ended box wrench
5. Wire cutters/crimpers
6. Heat shrink tubeing or electrical tape
A. Disconect the battery
B. Spray some WD-40 on them OEM bolt

The horn should come with all the parts you'll need to install it.

Step 2 unplug the factory horn that has malfunctioned. Both horns are located at the front of the car inbetween the radiator and the front bumper. The horn that broke on my car was the one on the left. Once unplugged use your wire cutters to snip and strip the wires leading into the male OEM connector. Now using the supplied spades crimp the new connectors onto the wires. For saftey reasons I prefer to wrap them in heat shrink tubing or electrical tape.

Now you'll need to unbolt the bracket that holds the horn from the radiator bracing. It uses a 10mm nut, spraying WD-40 before starting will help break the nut. Don't lose the nut, you'll need to reuse it later on.

Here is a pic of the old and new side by side. Look how rusty my stock horn is. The aftermarket horn is much bigger.

Now it's just a simple matter of bolting in the new horn and bracket using the oem nut, and connecting the spades. Don't worry about the polarity as far as posative and negative since most aftermarket horns are not polar specific.

Last plug in your battery and toot your own horn..

I left the working OEM horn plugged in because even though this horn is louder then both of stock horns combined I wanted a high and low pitch horn sound.

i am thinking about put a horn on my alarm so is louder than lojack one on my car. nice post.

Machine Head · 03-31-2003, 01:48 PM

this is very loud, now that i have done this I may consider installing a small air horn to replace the other OEM horn

Anyway you can make a .mp3 of the horn in action?

MR.CLIFFORD · 03-31-2003, 02:39 PM

Surprised someone actually likes my wheels as much as I do

You should probably be able to pick up a set pretty cheap on ebay.

Machine Head · 04-01-2003, 10:19 AM

hey machine... you know how you have 2 horn buttons on the steering wheel, is each button to one specific horn? or does each button blast both of the 2 horns?

Machine Head · 04-01-2003, 02:31 PM

Hmm good question.. I'll test it when I get home and tell you

G_Loc · 04-01-2003, 04:00 PM

they both activate both horns or else you would have to press both buttons everytime you honked or it would sound retarded

lol. yea that would be funny.

Padge · 04-01-2003, 04:56 PM

maybe you could change it so one button activates one horn and the other one activates a water gun.... or OIL SLICK!

i did the same with my car changing out for electric hella horns and airhorns. Well, I haven't gotten to the point of installing the air horns, got some 150db's=D. I have electric hella horns rated at 90 something Db's I think. They are comparable to stock horns but sound much like a real horn. In my case, I swapped, the electric horns I had both had high pitch and low pitch.
