with horns it is pretty easy to tell if they are in phase or not (in tempo and firebird i knocked 1 out of phase same with a corvette too) . also sit more up right and put your chin over the steering wheel once...think you will be in shock (if not there is something wrong). also wouldnt hurt to talk to eric either he helped me out both on the phone and in person. he knows horn set ups and can generally tell you what the deal is within 30 seconds...as long as what you are telling him is correct .
