Just got the B-Stock Damplifier Pro - 30SqFt with the spooky10 discount. Hopefully this will kill the ridiculous rattling in my car. Thank for heads up and the coupon!

Thanks for all your help. I had some trouble deciding but you made it easier for me. I'll be going for the single baffle, but will do the all 45s for some reinforcement. I also have another question, but the topic is totally unrelated. As I mentioned, I have a Camry with JBL integration. I am using the factory speakers but want to add aftermarket speakers using a 4-channel amp and my only option is to use high-level input to get a signal to the channels of amp. The problem is that the speaker is not a single 2-way speaker, but they are component set. I can only get the signal from one speaker, either the tweeter or woofer, to one channel, like this, so the channel can only pay highs (if I got the input from the tweeter) or lows (if I got the input from the woofer). How can I get a full frequency signal to a channel when they are separated like that? Is it possible to just take both positives and both negatives (from the tweeter and woofer) and wire it to the one channel? I know this question is out there so I may have to repost this in the amp forum; I was just wondering if you knew.

This is the tutorial for Torres' Calculator. It's very good; it also shows you how to draw it in Sketchup. http://www.stevemeadedesigns.com/board/topic/145174-ported-box-design-a-tutorial-updated-630/

Ok let me answer some of those: 1) Answered. 2) Not necessarily, also remember that the bigger the port the shorter the compression chamber becomes for a given volume. 3) It may provide a little better support like suggested but you can assemble it the way you want as long as is physically the same. Check your Torres to have # of common walls set to 3 and number of extra to 1 and all the rest, your result is low. on the double baffle, do it or not IMO yes but you can disagree and do a single baffle. Thanks for answering my questions (and quickly too). It really helps since I plan on building it this weekend. I checked Torres and I got the same number as the screenshot above. Would you (or any one else) mind answering my other two questions? I guess you missed it before. "Basically, is your box design (the sturdier, more air flow box) worth the 0.5 cubic feet lost in volume? Again, I'm new to this so I'm just going by RE Audio's 4.0 cubic feet for "optimal", but since I can't have that big of a box, I just figured, the closer to 4, the better. Am I wrong on this? Also, are the 45s in the other three corners not necessary? It doesn't show it in your picture."

Ahh, so that's what baffle is. I didn't know what that meant in Torres' calculator. Thanks for answering. @ Joe X. Did you use Torres' calculator to design that box? I couldn't get the volume to match up. It came up to be 3.08 cubic feet when I did it: Basically, is your box design (the sturdier, more air flow box) worth the 0.5 cubic feet lost in volume?

Thank you for your suggestion, Joe X. I have a couple of questions about your design. 1. What is the advantage of the double front? Won't that cut internal volume? 2. Does increasing port width and length make it sound better? 3. Is it better to cut the top and bottom as you designed (28 x 19 1/4), or can the top/bottom be the base (28 x 21 1/2)? Thanks for your all help. Looking forward to more advice!

Thanks for the response. Unfortunately, I am restricted to those dimensions (21.5D x 16.5H x 28W). I was wondering if, restricted by those dimensions, this is the best box I can build. I will be driving the sub with a Hifonics BRZ1200.1D. I listen to a variety of genres, but mostly rock, metal, dubstep, pop, and instrumentals. Thank you for the warm welcome. I have a '09 Camry Hybrid (with the JBL system) with stock alternator; battery is a DieHard Platinum. I plan on doing the Big 3 upgrade. I have a Hifonics BRZ1200.1D and plan on running about 900watts to the sub. I also have the Boss NX3000.4 and will be running about 150watts to each channel. Thanks for the advice with the 45s.

Hey, everyone. I'm new to car audio and I hate to read so can you design a box for my RE Audio SXX15? Let's try that again... I'm new to car audio but I love to learn, so I'm glad I stumbled upon this forum. I have a RE Audio SXX15 and this is the box that I plan on building for it. This is the first box that I am building, so any tips is greatly appreciated.
