With any luck we'll be installing the four speaker pods into the van soon. Two in the lower front doors, directly over the stock door grill.
The other on a panel just behind the sliding doors.
I have already lined the inside of the pods themselves with Fatmat, and now I'd like to make sure I get the best sound from the speakers.
I have a few questions.
We have to cut the front door , integrated speaker grills out for magnet clearance with the speakers going there, even with the pods height.
Is it best to leave the old hole open so the new speakers have access to air behind the old grill? ie.the air volume inside the door, it'll be sound deadened also.
Or do you seal up the old speaker access and access to the air using sounddeadener?

I can make the pods air tight in other words, is that good or bad.

The set going behind the doors have no OEM speaker holes behind the pods. Seal them tight or make a hole behind it into the plastic skin for air movement?
Seal/don't seal the edges airtight to the door skin?
Other options?

Whenever possible, you want to keep the front wave separated from the rear wave.

depends on the drivers being used and if they like to be ran free-air or sealed.

MTT- I'm not even sure they say to run sealed or not with my old PG 6" , the box is long stored away, somewhere maybe the new comps coming in will say. I'll have to check that out, thanks. I never thought of the sealed/free air option with anything but subs and 6x9's.

Ohh man DS. That sounds like science.
Soooo, some sort of baffle design to reflect the sound one way or another, behind the speakers?
How about adding some polyfill??

Guess I should read up on soundwaves huh

I was simply saying block any hole that allows the rear wave of the speaker to "seep" forward.

^^as stated, depends on the speakers, and your pods volume. If the pods have the right amount of internal volume for the speakers, and the speakers are designed for sealed/IB application, then sealed is fine. Keep in mind that most car audio speakers are deigned for free air (door volume) or infinite baffle(IB) use, so most will sound "thin" or lacking reasonable midbass/bass if in small enclosures. Many higher end speakers have specs for sealed applications though, and just because it's designed for one style does not mean it won't work well with another design...so trial and error still rulles.
