haha lol thas my vid i did the other day.
Oh lol 
You ever fix that squeak your horns have? How do you have your horns mounted?
Mine did that and I had to replace the horns… It is starting to act up again so this time I am putting on a 1/2 SMC valve and gonna see if that will fix it…
mine sound fine. well i havent noticed a squeek. i have noticed them change octive if i lay on them for 3-4 sec tho
That high pitch sound from your horns is not right… Compare it to other videos of the shockers
Some other things to consider Switchbox: what PSI are you running at, and what size air line / fittings / valve are you using?
If you use less than 150 psi or you use less than 1/2" ID air line, such as 1/4" or smaller, then your Shockers will most likely have a higher pitch which is normal for your setup. On my own Shockers I noticed nearly double the volume and a much deeper tone when jumping from 1/4" NPT air hose up to 1/2" NPT air hose, but even at 1/4" my Shockers were still a lot deeper than that sound in your video.
The horns in your video sound like my old Omega AH-500 horns, which I have installed in parallel with the Shockers, so I can fire either or both for comparison purposes. They sound awesome together but when I only want one horn then it is the Shocker which gets fired. The Omegas are super loud at 150 psi on an 1/2" ID air line but a bit too brassy for my taste as a stand alone horn.
i am running 1/2 line, 1/2 valve and 150 psi. do you hear it in this vid?

i dunno why i don’t hear it. i get some more vids fri
yeah thats the same sound. its not suppose to have that weird high pitched sound they are suppose to be deep. thats the exact same problem im having with mine.
hmm. so what do i need to do? send the horns back fir replacement? i have only had them a few months
The original video posted first in this thread above was this one (Shockers in a tunnel):

The video that was posted next in the thread was this one (OEM, Psychoblasters, Shockers on a parked truck):

The first video accents the really high pitched brassy tone which sounds terrible, way too high for Shockers. The second video sounds similar but at least a little deeper, not quite as bad. Neither video sounds anything like my Shockers, which are a lot deeper and rumbly, not high and brassy. Some of this could be due to the camcorder, microphone, tunnel, fitting sizes, etc. but it seems that you still have a problem.
same exact thing happening here
^ what when its hot? or not getting 12 volts?
when it’s hot
Mine did that on my truck all the time,sent them in for replacement and replaced the valve and they still do it sometimes,but mine are mounted under the hood which traps alot of heat.Like stated before though,when its cold they sound amazing!
mine used to be mounted in the motor compartment and they sounded “squeaky” like that…i moved them ontop of my cab and now theyre back to the deep tone they should be
i think it was a mix between the horns getting warm from the motor and i think the lines were kinking a little bit also from the warmth of the motor
wtf? lol Just to add to this thread,I recently added a set to my car and im getting this issue at 150 psi on a hot day.They are mounted behind the grille.They are good after i hit them a few times but it happens again after i wait awhile to hit them.I think its just moisture from the humidity which is ******.
he fails. on with the thread
Yeah I said that cuz there was a bot spamming in here but they deleted the bot’s comment and not mine lol… just to explain why I said that. I deleted what I said now though.
i have the same problem with one of the set , but only does it when psi is at 175. maybe that the back screw needs a slight adjustment? i have to check each horn at a time. hope the diagfram is not torn?? or crack??
Find what horn is squealing. Tighten the tension on the back cap a 1/16 turn. Then fire off again. These horns are slightly on the sensitive side. if that doesn’t work do another 1/16 of a turn. You might have to do this to all of the horns. But start with the problem one first. You want to achieve even air pressure to the horns. If out of wack the the smaller bells will sounds first.
Post up how you make out.
