installing air horns in the Q

Post by **qship96** » Tue May 24, 2005 6:35 am

I am inatalling a Fiamm dual trumpet air horn-can I wire the air compressor {15 amp} directly to the q horn wire,or will a relay system need to be installed? FSM shows the circuit to be a 15 amp if I am reading it correctly-anyone try this setup yet? stock horn,while weak when new,is getting weaker with old age!

Direct plug-in, no relay required.

Mine's been that way for 2 years, not a problem.

Greg: DOn't want to do that. Too high of a current draw for such tiny wire.

I recommend using a relay connected to the Q's horn wiring.

*edit* I was thinking about installing a train style air horn on my Q. That ought to be good for giving th eold guy infront of me a heart attack

unless you can verify your horn has a higher amperage relay, i would wire a relay..

On my maxima, I have the +12v on the air horns wired directly to the battery fused. I use the car's horn wire trigger a relay which supplies ground to the air horns to complete the circuit.

When I had it wired directly, it kept blowing fuses. I found out the horn relay was a low amperage relay causing a circuit overload.

i have 2 sets of air horns wired directly for years now w/no problemi set up frontand one set in rear of engine compartment

james,why 2 sets? what do the ones in rear of compartment do?

Apparently you guys missed the part of his post that shows the FSM designating it as a 15A circuit.

Like I said, it will be fine. I have had mine wired as such for 2+ years with no consequence.

The Q desperately needed a serious horn, and the 139dB unit I installed does the job.

The convertible and Pathfinder will be getting one soon as well. Search "139bB" on ebay, they're self-contained and run about $40.

Where are you guys getting your units??? I want to do that sometime, as when i honk my horn people laugh at me

You don't have an air horn do you? Most likely you have an electronic compression driver that takes about 12~24 watts. = 1~2A

ALL air horns require a compressed air source. This is usually a small compressor with a low volume storage tank. If the Horn is indeed rated at a continuos 15a then it definately WILL blow a 15A fuse sinse ALL motors draw atleast twice of their RMS power upon startup.

Sinse you're already in the engine compartment why not just connect a relay with power directly from the battery? Not too much work and you're SURE that there won't be a problem.

Greg, how much was your horn?

Anything beats the weakling beep of the Q.

Yes, it's an air horn with a small self-contained compressor. No, it's never blown a fuse, and yea, it's loud as all hell.

What does it sound like.. is it just a really loud horn, high or low pitched...?

Post by **AZhitman** » Tue May 24, 2005 12:33 pm

Um, sounds like an air horn.

Not low like a foghorn, not high like a stock Q, in between.

Call me and I'll put the phone up to the horn for ya.

Oh, sorry for doubting you Greg. I just like to play things safe, you know? If you use a 20amp relay you can run quite a few horns off of it.

As long as its screaming "I own you" or "get outta my way" or "your flaming slow" thats perfect...

When I went down to the dominican the busses has multiple horns... The regular horn was honked at anything that came within 10 feet of the bus, and the other one was used for everything else. Our bus driver said, the first one was used to denote "be careful", and the other one was "you *insert adjective* idiot get the *insert adverb* out of my way"

Well, this one says, "Get the *** AWAY from my car!!!!"

Keep in mind the alarm uses the horn as well.

i've seen these on ebay, and plan on getting one (thanks for your previous heads up greg!). i used to think about matching the perferct horn tone to the Q, but think about it, the only time you use your horn is to get someones attention. and,,,if some a-hole is ready to slam into my Q, i want the loudest, "attention getter" screaming from under my hood!!!!!! get the air horn!

Post by **zinkie13** » Wed May 25, 2005 12:32 pm

At some point I am just going to get an air compressor and a horn from a semi. Then i'll really be able to make some noise

Post by **maxnix** » Wed May 25, 2005 12:42 pm

Yeah, I want one of those three foot chrome trumpets on my front fender.

In '73 I bought a 72 Olds Cutlass, it had the best (LOUDEST) horns of any car I've ever owned. They looked like any other car horns, someone told me they were 'noise pollution' horns. Never found any since that came close. First time I honked the Q I had a flashback to my 383 roadrunner. meep meep

Post by **nuQ** » Wed May 25, 2005 2:15 pm

do a search on ebay for 72 cutlass horns!!!!!

Post by **AZhitman** » Wed May 25, 2005 2:31 pm

Haha, had the same ones in my 68 GranSport (Buick). Loud as hell.

Not as loud as these, though.

p.s. 68-72 GM A-body cars: Mmmmmmmm

I've done this to my 4Runner. Used the stock horn wires and fuse. I've had this in for 3 years and what a difference.

Pepboys.

Click to hear the factory horns first and the air horns second.

I like that the airhorn is louder, but it still sounds a bit girly IMO.

I would want something that sounded like a train horn.

Hitman - Do you have any pictures of how and where you hooked up the horn?

Wes - Could you get one and do a write up on it to share with the rest of the us?

Post by **PoorManQ45** » Thu May 26, 2005 8:56 am

heRE, I'll do a write up.

Cut wires going into OEM horn. Cut back insulation enough to splice together with another wire. Then connect wire supplied with horn to OEM wires. Polarity doesn't matter, so don't worry about which is positive and negative.

Post by **elwesso** » Thu May 26, 2005 10:12 am

Thank you PMQ, that was vitally necessary...

Im gonna pick one of these up at some point and time and wire it up...

The one that Jason posted was a little too high pitched for me.....

Post by **jamesmost** » Thu May 26, 2005 10:29 am

actually 3 sets, forgot i have 2 sets up front and 1 set where the rear horn used to be just different tones and louder, when i hit my horn it is ususlly because i am moving fast and really want the person that is about to do something more stupid than what i am doing to know i am comming down the pike
