Well I did it!
I attended my first ever and competed too in an SPL Competition.
There were about 15-20 cars there.
Not knowing what to do when I got up to the staging area, I had 30 seconds to get my highest DB. A friend of mine and myself had played around with some CD/HD Quality Tones. We found, or felt it was loudest at 41 Htz in my car.
But today, after talking to some other the other competitors, particularly one guy, Tom, who was not in my class, he told me to stair step the tones from 40 - 50 Htz. So I staged and I was nervous. The timer started and I started stepping. I topped out at 131.6 Db at 45 Htz. 30 Seconds go by FAST!!!
Later we did some more testing, not on stage, but with Tom'* help, he says I might have done 3 - 5 Db better if I had run in the "OUTLAW" (windows down) and hit at best 47 Htz.
Tom, has the termpro meters at his garage and we are going over there in a few weekends to tune and test my car out.
My class was "CAR" + "CLASS B" + "STREET/LEGAL"
I was the only there with a Sealed box. Tom says the SPL comps are more or less won by ported boxes. I learned alot from today, terminology, how-to'* etc..
I am going to try this again in a few months and be better prepared. He thinks I can get possibly closer to 138 Db or so with my system.
Oh.. guess what, I pulled away with 3rd place trophy!!!!
