fecupe2001 Posted December 11, 2011 Report Share Posted December 11, 2011 Why do you want to be louder sealed up? are you gonna compete at db drag? you can always compete on usaci, meca or another association,my suzuki swift was the same way that your car is right now, my explorer is backwards and man, i HATE the explorer so much, i´m all about demos, demoing a car with everything sealed up it´s just lame if you ask me, specially on the shows where you have lots of people gathered around your car to see everything, i prefer to be louder with both windows open all day long!!!

varietyguy Posted December 12, 2011 Author Report Share Posted December 12, 2011 This will be my first year competing in meca. I was also wanting to hit a few local dbdrags too. I am completely sealed off in the front and back. I just finished my build yesterday. http://www.stevemeadedesigns.com/board/topic/126066-mazda-323-wall-build/page__p__1775338__fromsearch__1#entry1775338 . I also am very disappointed. I tuned the box to 36 hz. But I have absolutely no lows. Again, I still need to put it on a termlab, but I played young Jeezy's "Put On" and I'm pretty sure my 6.5's have just as much bass as the 15's do that low.

fecupe2001 Posted December 12, 2011 Report Share Posted December 12, 2011 The lowest frequency on that song is around 27 hz iirc , a 36 hz tuning is not the best for that unless you have a very low f3 wich is kind of hard to get, maybe you set the subsonic filter way too high? About the wall, i guess you´ll have to compete on meca, usaci and the other associations that use an open door and forget about db drag unless you bass race on the 139.9 class for example, is not the end of the world actually, enjoy your new wall Quote I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.

irvin productionz Posted December 12, 2011 Report Share Posted December 12, 2011 I just finished my wall and I am fairly happy with it except for one thing. With the car doors open it is pretty loud (haven't metered yet.) but with the doors shut it is substantially quieter. If I were to guesstimate I would say between 5-7 db difference. My dash and everything in the car shakes with the doors open but sealed not too much is going on. I know that it has to do with frequency and box design. But how can I retain the pressure with the doors shut? that happens to me, i hit the lows harder with doors open or windows down, and the higher frequencies harder sealed, but i have it on a single cab Quote Link to comment Share on other sites More sharing options...

That´s one loud car for some demos, i wish my explorer were like that, no matter what i build, i´m always louder sealed up, as soon as i open a door, output drops A LOT, that sucks for demos if you ask me , having to demo the car with everything sealed up is kind of boring if you ask me Quote I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.

RooTxBeeR Posted December 13, 2011 Report Share Posted December 13, 2011 So if I do a bigger enclosure will this help or hurt me? Same with port? Not saying you made a bad wall. It's just the acoustical characteristics of your car. By opening the door or crackin' a window you have just created a second tuned enclosure. Pressure should be greatest at the opposing side of the open door/window. To what you said sir, so Driver window down, passenger louder? and vise versa? Also does this apply for port to, if I have port driver side, passenger louder? to OP: I am in the same boat as you, I have a civic hatchback. When I am sealed up I have my high end, but nothing under about 40hz, but man. Open the door or window and my god shit starts shaken.
