Thanks for the info, that's helpful! I love good tight clean bass so I was planning on building a good sealed enclosure because I was told that its the best for creating that kind of bass. What's the difference from these IB enclosures and a sealed enclosure like I was planning? I was also thinking about completely removing the back seats in the BRZ so the subwoofer enclosure can sit right where that opening is. Use some nice plexi-glass and have a nice clean set up.
Do you know why people keep trying to talk me out of using the two 8" subs for one 10"? I keep thinking that two would be better for a clean tight bass set up and I would be able to save weight over 10". I guess I've been away too long, but I don't need or want a ton of bass. I've actually been really pleased with the stock 8" sub we had in our Toyota Tacoma and it wasn't that great.
