trunk air presure

I have subs in my trunk with 6x9's on the rear deck....When I turn on the subs the 6x9's get sounding funny from the air presure in the trunk...What can I put around those 6x9's to keep them from moving from the subs presure??

If you haven't Dynamat'd the under the speakers - try that... and maybe stuffing some poly-fil behind the baskets...

There isn't much you can do, other than build solid boxes for the speakers that hang below the rear deck. Strengthening the baffle won't do a thing, the pressure is moving the cone itself, not the baffle that the speaker is mounted on.

You can actually buy baffles that are pretty solid and place them on the bastket of the speaker, saying that the 6x9's are not already in baffles, (most arent)

You still run into the problems I listed

If the baffle is not COMPLETELY air tight against the rear deck, then it would serve no purpose
If the baffle is completely air tight, then you cut all the low frequency extension and efficiency of the speaker
