How will RSD 6.5s sound in IB

I know they are suppose to be sealed to get that incredable midbass, but I really want to mount them in the stock door location. The actual speaker itself isnot mounted to the interior door piece, but to the metal under the interior door piece.

If I was to completely sound deaden the doors, how would it sound?

The stock location is 5.25 so I already have to get the shop to make baffels to hold the 6.5s

No problem at all. They certainly don't need to be sealed to make a retarded amount of midbass. A bit of sound deadening, maybe a deflex pad, and you're good to go!

Can you cut deflex pads to fit the speaker opening?

if their is a little "pod" like i remember there being, then yes, you could cut the pad to fit the back of the pod, and use the exess for the sides

Hey what did you mean by deflex pad, like dynaxorb?

Is it pointless to put a deflex pad behind the speaker if all that is directly behind it is the water barrier?

And when people are saying IB, do they mean open-backed or does it mean open-backed and vented into the cabin somehow?

I'm pretty sure IB means NOT vented back into the cabin.

So it just means open-backed to the inside of the door or whatever?

Yes, for an "infinite baffle" configuration you want to completely isolate the airspace in front of the speaker baffle from the airspace behind this plane. As long as this isolation is good and complete the driver will behave as if it's an incredibly large sealed enclosure. "Free air" is the term best used to describe a speaker that isn't in a sealed enclosure and hasn't been properly installed to isolate the speaker's front waves from the back waves. Or in other words, unless you go to great lengths on the install to completely seal off the plane the driver is mounted on in a door install then it's technically a free air setup.

damn, i'm a wordy bitch!

No that is very helpful, it seems like different people consider different setups IB when in fact they may not be. Thanks.

Now regarding a deflex pad, is Dynaxorb that?

Cascade = deflex
Dynamat = dynaxorb

they're both pretty much the same thing; a profit center created by the marketing teams at each company!
