larger horn for Cavalier

I have a '92 Cavalier. The horn is anemic, it really is almost worthless, lol.

I would like to simply go to the junkyard and get a horn from a Buick or a Cadillac...etc...and install it in my Cavalier...

But I wonder if  any of the components of the electrical system in the Cavalier would be fried by ( I assume) the larger electrical requirements of a more powerful horn?

Anyone in here know if  simply hooking up another (larger) horn to my Cavalier would cause any type of problems?

Thanks in advance......

thanks for taking the time to reply pat28

of course i am hopin'  the horn will sound better, lol,  as it is it can barely be heard ..and on the interstate next to an 18 wheeler it's as if it isn't even audible

i know i can "go right ahead"  and it would work...for a while...

but what i fear is that OTHER parts of the (fragile) Cavalier electrical system might not be heavy duty enough for a higher output horn from a more substantial model of GM car

that's why i am seeking advice from someone more knowledgable than myself

What about the horn relay?  would that burn out? there used to be a thing called the voltage regulator ( i may be dating myself here, lol) might that  get fried?

..anyway...I just dont want to slap in a $10  junk yard horn from a Cadillac and later find out that i have fried some $400 part available only from the Chevy dealer....

Anybody else have an opinion????

hook it up the way that mobile says. just remember that there are different types of relays  the spdt means" single pole double throw" .  see current is like having water and you are trying to fill a bucket. small bucket means that you will reach it's limits quickly. large bucket , you can fill it till the cows come home. so if you got a better horn, then chances are that you'll be ok
