I just had this idea and I wanted to know what you guys thought about it (if it would work or not). I am in no way electrically inclined...so my question might sound kinda lame. I have the stock single horn on my car and i was thinking about just getting another horn and mounting it on the other side of the car from the first horn. my question is this: could i just strip a small portion of the insulation off each of the wires currently running to the original horn and solder a wire to each of them and then just run those wires to the new horn? would this just make the original horn and the new horn both work at 1/2 power, or would they both work at equal (normal) strength?
I know everyone likes the supertones...but i just got this idea as a cheap alternative and wanted to get some opinions on it.

 

Yep, it'll work. I've done it on my wife's 99 EX. It's a little bit louder and sounds like two cars honking at the same time. I took the one off my 00 Si and replaced it with Hella twin tones and put that one on her car. Just splice into the factory wires and it'll work great.

 

Try getting a horn for a 99-02 Accord. It's louder and it plugs in without modifications.

 

sweet, sounds like a short new project for me!

 

Well, you have two options when wiring the second horn...

If you wire it in serial, both horns will operate at half voltage, and if one breaks the circuit, they'll both stop working. Series is when you wire the 2nd horn in between the 1st horn and one of the wires going back to the car. Wiring it this way for your horns is a bad idea, and I don't know if they'd even operate at all with only half voltage. FYI, this is the type of circuit that causes all of your christmas lights to go out when so much as one bulb burns out. It does have it's advantages, but it wont do you any good in this case.

If you wire it in parallel, both horns will get the same voltage, and if one stops working, the other will still work (unless there's a short circuit, which would also blow the fuse). Parallel is when you wire them the same... ie positive to positive, negative to negative. And that's how you want to wire your horn.

So, just splice into the original horn's wires and extend the positive wire to the 2nd horn's positive connection, and negative to negative. The same wires will still be going to the original horn; you'll just be making a "fork" or a 'T' in each wire that adds a path leading to the 2nd horn.

 

my stock horn was making this wierd tone.. where it would sound muffled.. then would suddenly get loud again.. then muffled sometimes...

my horns are LOUD!!!

I got hella's but I also got the stock horn (which works whenever it feels like it)... I used a relay and the stock horn is just wired stock... the hella's are wired to the relay which is wired to the battery and grounded and it gets its signal to activate/sound from the stock horn trigger... when I honk people both the stock horn and the Hella's go off. it sounds like 2 people are honking and its really loud...

I also connected my hella horns to my alarms "pulsed/horn" output... so when my alarm goes off.. not only do all the sirens go off.. but the horns go on and off (pulsed)... its loud!!!
