Sonofthor Posted November 4, 2013 Report Share Posted November 4, 2013 Rounding the port makes it also longer, so maybe your tuning is a bit to high, so you gain with this "longer" (lower tuning) port also. Don´t forget this rounding inside the box on the port that´s why i tried to round the port with a very small pvc stripe, so i wouldnt change the tuning that much, but hell, looking at your signature then you are definitely a guy with way more knowledge than myself, if you say it was lower then it was lol I always make it with a round piece of wood and cut it in the middle, nearly the same size as the pool thing (see in the pic) But keep this good work going 2008: Street B - 160 dbzzzzz 2009: Street B - 160,8 dbzzz 2010: Street B - 159,7 dbzzz 2011: Street B - 159,9 dbzzz 2012: Street B - 160,0 dbzzz 2013: Street Stock - 153,6 dbzzz Link to comment Share on other sites More sharing options...
KickersintheTrunk Posted November 6, 2013 Report Share Posted November 6, 2013 Do you think laying the rear seats down in my 06 Pontiac G6 Gt coupe would increase SPL? Check out my Youtube channel www.youtube.com/user/ologiic Link to comment Share on other sites More sharing options...

funky Posted November 14, 2013 Report Share Posted November 14, 2013 This thread is awesome! Just ran across the thread and I am not a big poster but I must say this one deserves it! I am currently at 147.9 can't wait to try all of this and see how each one changes me would love to see me at 150 it is a daily built for music I am flat from low 30's to high 40's with a tiny peak at 44. Great stuff thanks so much for starting and continuing the thread! thanks man, glad you like it!! very good score, try everything you can from this topic, at least 50% of them are going to be useful on your application Just so you know I did a bunch of different configurations inside my vehicle and went from 147.9 to 148.9 with my c pillar wall! Then I changed the port and took my amp to .25 ohms got it up to 151.5. In the middle of a rebuild going to go for 4 18's now in a c pillar wall! Learn to live life, not just be alive!

Psych0ticNemes1s Posted July 1, 2014 Report Share Posted July 1, 2014 I rounded over my entire box including the sub hole, but I didn't gain. Have you tried putting resin on the inside of your boxes? I've heard that's a decent gain. Also, with the ac on im pissing air out of my door handles, side mirrors, gas tank lid and passenger side window. if I figured out how do seal all that do you think I would gain?

Yes i´ve used resin tons of times before, sometimes it gains a few tenths and other times i lost tons of tenths, depends on the application i guess, honestly speaking i got bored of using it lol If i were you, i would start with duct tape or gorilla tape and just seal those things and test on the termlab I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.
