Posted August 1, 201114 yr As some of you already know, i've decided to add a 3rd xcon to the 2 i already have for a setup in my civic. I've pretty much got everything i need. Just need some more wiring and misc interconnects. Amp, too. Anyway, while talking to my box builder and the guy that helps me out with installs, he told me instead of running sealed with the xcons, i should run them in an IB config. His reasoning being1. Sealed requires more power to hit the same SPL while IB requires much less. less power to use = happy electrical. 2. I'll retain about 80% of my trunk spaceI've never had an IB setup, but i've heard a couple and they've sounded amazing. They were all 100% sq setups, though. Will 3 12" xcons work IB? According to the manual, There is 11.9 cubic feet of cargo space. I have just enough space to squeeze 3 in there. How much will i need to seal the trunk off? The goal is a clean, low distortion setup that doesn't lose its composure at higher volumes.
August 1, 201114 yr If this guy is telling you to do your 3 xcons IB in your trunk I highly recommend another installer. You won't end up with an IB set up. You will have what amounts to a leaky 11.9 sealed enclosure
August 1, 201114 yr Author Do you mind explaining?I "kinda" understand the purpose and science behind it, but i'm still sort of lost. Edited August 1, 201114 yr by eggyhustles
August 1, 201114 yr IB won't gain you much SPL wise, IB is definitely not designed for chasing numbers.

August 1, 201114 yr I see no problem running an xcon IB however running 3 in your trunk is getting close to the volume 3 subs would use in a normal enclosure. So you end up with back pressure just like a sealed enclosure. In other words your trunk will be pressurized just like a box would be
August 1, 201114 yr Yep, and the idea behind infinite baffle is there is no air spring on the driver, the only thing controlling the driver is the suspension and the idiot behind the volume knob. You could install them in this configuration and spend the labor making 100% sure the front wave is entirely sealed from the rear, but that would be (in this instance) nothing more than a sealed enclosure.
August 2, 201114 yr Self defeating. Why are you adding a third? *and yes I can guessAnd for that reason you will be taking a step back from your goals by going 3 IB versus 2 sealed. If you want a third, then box it as well.
