Eduardo Andrade Posted May 11, 2012 Report Share Posted May 11, 2012 Hey guys, the one area I'm least experienced in is building boxes. In fact, I've never built one, I mean I've watched videos of people building them, and I know I can do that part, my friend who said he's built boxes before said he would help me, but I've never DESIGNED one before. I was wondering if you guys could help me out with that part, either quickly design one for me or teach me how to design one. This is what my trunk looks like Not perfectly measured, but to be safe we can say it's 17in tall, 37.5in wide, and 31in deep. I plan on using 2 sa-12's and I want a simple ported box tuned at maybe 31hz if possible. The subs and port will both be facing forward (into the cab) so that when you pull the rear seats down you hear/see the subs and port.

Eduardo Andrade Posted May 14, 2012 Author Report Share Posted May 14, 2012 (edited) I was actually hoping to have the port in the middle. I'm not asking you to redesign me something but it would be cool if you could! Although, asking for a design WAS the intention of this post. lol so yea, that'd be cool if you could!

Eduardo Andrade Posted May 14, 2012 Author Report Share Posted May 14, 2012 (edited) Okay guys, I really appreciate the help. Today I just took accurate measurements of my trunk, and it looks like my box is going to be 15.5" tall max, 35" wide max, and those are the dimensions I want to use, 15.5" for height and 35" for width, now for the 3rd dimension (depth) I was wondering how an L shaped port like you guys did affects the internal volume and/or tuning frequency, I was messing around with the Speaker Box Tuning Calculator software and I'm assuming they just use a straight port. The way the box is designed doesn't matter to me, I'll keep the L shape if I have to, but what I really want is a box 15.5" high and 35" long to wall off the seats when I pull them down. Anyone wanna help out here? By the way, thanks for all the help guys! Really appreciate it! Bare with me, I'm kinda new lol. Oh yeah! And what kind of software do you guys use to draw/design the box out?

john253a Posted May 15, 2012 Report Share Posted May 15, 2012 (edited) Any preference on meteral I prefer 1" with spans over 12" and up, but 3/4 is more then enough when braces correctly, Have you also measered the angle of you back seat or do you plane on not sitting it flush at bottom Another thing to consider is the trunk opening I normally measure this and make sure the box will fit through door, Another hint is if the max measurement between wheel arches is 35" then you may have trouble fitting box it due to trunk door not allowing box to fit straight in. If it does then your ok If not make the 35" equal the diagonal of you box and it will normal fit easy as Edited May 15, 2012 by john253a Quote Link to comment Share on other sites More sharing options...
