It has a range of 35 to 135 Db   That level was reachable with a single Punch 45 in 1985.

Why is that "funny"? There is a reason the thing is being "clearanced" for 15 bux! It's a turd. 135dB is kiddies territory; ANY system will likely peg that thing. The Term-Lab piece is FAR more like what you will be needing. Don't want to buy it? Rent it from someplace, but if you want to be REMOTELY taken serious, you'll forget the Wally World SPL meter right now.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I think he was amused at how I was trying to say that the capability of the wal-mart meter is child's play, without really saying that. Now I realize "kiddies territory" may have been a better choice than "child's play"
Haem, do you have Photoshop, PaintShop Pro, or even Microsoft Paint? Have you seen the Administrator's new bike? It is in the Rides and System Galleries forum. It needs some customizing.

First do a google search and maybe look around "usaci" site. you dont want to have a soundoff and look like a complete idiot, if i went to a sound off and they metered with trunk open i would lmao and leave. 15 dollar decibel meter is not at all accurate so LMAO at you. no one said car audio is cheap, you get what you pay for..and you your question about how  to actually meter sealed up and on windshield as stated above or in the kick pannel with door open.

haemphyst is compyuter illiterit.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

hahaha
I have both a term-lab and various other meters to play with.
Walmart "boom stick" close to 20db inaccurate at most frequencies below 80hz   where you would want them to be accurate.   above 8- hz can be withen 1 to 2 db from a term lab haha
The volt meter style that is all over ebay is about 4-7db inaccurate from the term lab, but is consistant across the frequency band, but has alot of varience.   from 1 burp to the next it can change multiple DB
Older AudioContol meters   
180SPL meter is very very close to the term lab about 2-3 db and very accurate
170SPL meter is about 4-7 off and can be fool by finding the meters sweet spot
160SPL meter is about the same as 170 but easier to fool
Review formats and rules of diffrent sanctioning bodies USACI DBDrag MidwestSPL IASCA ect ect
decided what you want to go off os, and find a meter.   If you were anywhere in the US I could find someone to assist you or possibly host a show for you.    But in canada its slim pickings
You might want to PM velocitymotorsports or forbidden and see if they know any organized competition bodies in canada
