Wow this has to be one of the best, if not THE BEST thread here on smd - I have never spent so much time on a single thread :) It was shown to me by another member after explaining my goal of reaching 150db from 149.3. I got another comp this Sunday and am excited to try out some of these tricks to see if I can get my 150. First thing gonna take that carpet off my box and then flare the inside of home made aeroports.... I can't believe I took the inside flaring for granted wow... oh and the ground straight from the battery! Im all excited now!

Plan to build the same exact box in a few weeks anyways but with birch this time instead of mdf....

hehe nice to read such a positive comment, people like you were the reason i continued testing so many things hehe, glad you like the topic!!!

Those are definitely some nice gains, the carpet can get you a couple of tenths, but yes the flares on the inside should be your biggest gain , also, you can´t see it on this topic since i haven´t updated anything yet, but, i tried 2 grounds from rear battery to chassis and gained .2 dbs also, along with the run from the front battery to that second battery you should get a NICE gain!!!

Can you please keep me updated?????? would love to know if you reached the 150 mark by doing only those 2 or 3 things on the topic, i´ll be looking forward to hear any news about you!

Will "glassing" the inside of my box help?! Putting a smooth coat of fiberglass on the inside should give me a little better airflow..

not always, every application is different, we actually did this a couple of weeks ago on my buddie´s toyota yaris, boxes were rattleing a little bit , he didn´t gain a single tenth and peak went from 40 to 45 hz, i guess the peak raised because he lost a little bit of internal space, don´t think it was because of the box resonance or something like that.

It´s like the 45´s example, i´ve tested that a lot and i think it´s a big waste of time unless you are walling the car or building a non walled box for spl with everything facing forward like the europeans commonly do on pandas and small hatchbacks, that´s why i almost never glass or 45 any of my box, just build it strong and that´s it!!

its one of the things you hear people talking about and saying it helps. you can alwyas try it. Ive heard of people losing by doing that as well.

Indeed!!!!! how are you bro??? never saw a vid or anything from your build, got the 55´s ?? cheers!

the big thing about resining the inside of the box is you have to take the time to sand it down and make it smoooothhhhhhhhhhhhh... i have also seen a few gain by resining the outside of the box as well.... including me :peepwall:

This isn't teeball. YOU DO NOT GET A TROPHY JUST BECAUSE YOU SHOW UP. Put the work in and then maybe get the respect when it has been earned
