Outer door panel vibrating affecting midbass?

[hondarider 10+ year member]

So i deadened my doors about a month or so ago and been trying to figure why im lacking midbass. I think i found out today the outer layer of the door (the sheet metal that is painted on the outside of the car) vibrates alot....alot alot. Do you think that is why my midbass sounds so weak? What should i do just a couple more layers of raammat? It already has about 1 layer with a couple extra right behind the speaker but obviously thats not enough. What do you think?

i suggest you out some ensolite or overkill behind mid also. it made a world of difference

did you seal the door or just deaden it?

I did seal the door as best as i could with sheet metal and raammat overtop. I realized its the subs that are making it flex. If i turn them off there is no flex in the door and im still not getting any better midbass.

I am not a expert by far but i do alot of reading on these forums. I just got done installing a 720 prs set in my grand prix this weekend. If the outer door skins dont vibrate or flex with only the components playing it dont seem like you are wasting energy there, so more mat wont help.

I would first look at the speaker rings. Are they tight, no air leaks, mdf or plastic, are they overall secured well. Also did you rammatt around the mounting point. The whole thing is are they secure to a strong mounting point. One other thing is look at the settings on your hu. I know it sounds stupid but i play with mine so much i dont remember everything i adjusted for lower quality speakers. I only have one layer of rammatt on the outer door skin and some extra behind the speaker itself. Then i put one one and a half layers on the inner door skin and then ensolite over all that.

I have outstanding midbass so i dont think it is the speakers. Also make sure your wiring is right also, if one is wired backwards you might have cancellation issues. Hope this helps

Where's your HPF set? Any eq'ing done? Is the phase correct on both mids?
