hypothetical scenario:

your cruising on the highway in your freshly swapped beast of gt4 conversion. suspension is right. the interior is perfect. and the engine is just what you always dreamed about. along comes a punk civic and starts to mess with you. naturally you ran circles around him and went about your cruise. minutes later that same civic swings by to spite you. it veers in front and slams on the brakes. first instinct is clutch, brake, swerve, then horn. everything is good till the horn part. all of a sudden your badass gt4 releases the puniest squeak of rage that any car has ever emitted. the civic ricers off, laughing the whole way and you are left staring at the center of your steering wheel going wtf?... such is the truth of our stock horns. i've already experimented with some aftermarket horns but i cant find a good combination. someone told me that you have to get one high and one low for it to sound good. others say its bad to mix.

does anyone have a working combination that they recommend? buying this stuff isnt an issue since working at advance lets me swap out as many as i like. perfect example would be:

d low tone together with a b hightone or something like that. so far ive tried a d low tone with a stock horn as well as two d low tones together.

id appreciate some input

I am going to put a small air compressor I had in my rock crawler with a small air tank and hook up a train horn! My buddy has one on his 4 runner it almost makes you fall to your knees it is so loud. No one will expect that sound from a Celica!
