Is it possible to slap up a piece of MDF to wall off the trunk and car cabin and seal the trunk up insanely good and use an IB subwoofer for this? how many subwoofers am i limited too for an IB set up??

Do IB subs on the deck, that would be cool. Stock IB speakers sound awesome on the decks, if you are on a budget and want to experiment, get some IB 6x9s on like 100w or so each. I have only seen midbass 6x9s before, but if they make subs that would great.

Too much metal cutting and work if i can find a 10 inch IB sub and i can possible do six of them without interfering with each other i would most defintaly do that. But i am 100 percent noob at IB stuff
Just do 6x9s to experiment and see how they sound if you already have crappy stock ones, they slam nicely!

Basicaly what i got in my step moms car now. Two kicker 6 1/2 inch speakers. They shoot soundwaves into the trunk and the others in front echo into the cabin. Sounds really good i like it alot.
you will need to seal it very very well, and one piece of mdf will not work it will flex way to much

How much MDF will i need i already know i need bolts and lots of deadning and poly fill.

Are they made for IB and do you have an amp on them?

I have no idea if they are and they sure seem like it and no just the shitty OEM head unit
Well GL man. You workin now adays?
Nope but spring is looking forward to me and looks as thought i may get a job that can end up with 1100 in 2 weeks or 600 at lowest depending on how i work.
give me a half hour to get done and I'll type something up for you

Ok sounds good man!
cone area is needed with IB, you should use as much as you can fit.
the baffle needs to be be very rigid, I would use 2x4's with .75 mdf layer on each side.
all openings need to be sealed off completely. that means taking seat and panels out and sealing every hole no matter how small it is
you want a weaker motor for IB to keep subs from bottoming out they have no resistance at all so very little cone control
let me know if you need to know anything else, and yeah I have done an IB install before

So if you dont mind me asking. I am assuming the sealed off area in the trunk is acting as a pressure barrier from keeping the sub from moving too much. is this also possible to port it cause iv seen it done before where it was ported and got crazy lows.
sub will act as it will being played dipole, it won't move as much as it would free air but the volume in the trunk is to much to actually control the woofers movement
and you do not want to port IB, it will already be playing very very low. all porting will do is lower performance

Thats crazy. I like asking questions if you dont mind. Another thing what size sub is the IB limited too? is there a 10 inch version? and also should there just be one sub or can there be multiple
it's limited to what ever you can fit. you want to look for a sub with good clearance low to medium motor strength and decent but not stiff suspension. you deff do not want an spl sub

But will it boost the performance any if i add multiple subs?
Cone area is king. Strong baffle and fully sealed off trunk. Its not cause of pressure its for keeping the rear wave from the front wave. Low motor force subs sound like ass when you put real power on them. Screw that HIGH QTS everyone talks about it doesn't work well.
