Polyfill in sealed doors???

[Gunk]

I was just wondering if stuffing a bunch of polyfill in a waterproof bag and putting in my front doors could give me a better mid bass response.

My doors are sealed up pretty good... a little hole for the handle and lock levers to pass through and a spot where a wire bundle has to pass through but other than that, pretty air tight.

The bass just sounds different than I expected... like its kinda, hollow? Can't really figure how to describe it. I got one piece of open cell foam in a bag glued directly behind the speaker but its not that thick of a piece.

Anybody ever put polyfill in their doors??

I’ve never had a door be too small personally. Normally the opposite and filled with spray foam. Even with two 10s.

Yea, its a Neon. Small doors. Getting the 8 around the window crank on passenger side was not fun... One door is power other manual.

Lol. When i got the car, the driver door was dented bad. I replaced it with a junkyard door from a different model... that one had power window/locks. So my driver door has a power window.... kinda nice. I couldnt figure out how to wire the power lock. Its on a weird circuit that isnt just a 12v on/off.

So, would you guys say the Crescendo PWX is designed more for mid bass or to just do midrange loud?

The guys at DIY are telling me its not made for midbass and I should get the Eric Stevens MB8.

Pwx is a great midbass woofer.

Maybe I just need to give em more power.

The amp is rated at 125x4 but the dyno has em doing 175x4 @ 4ohms. Thats one reason I settled on this amp.
I could bridge the amp to get 400x2 @ 4 ohms... and I would expect thats underrated as well. But maybe giving the 8s double the rms they are rated at is asking for trouble...

They can take some power. I had my 4 10s on a DSP3000. Never clamped power to them though.

Did you have your 10s in a sealed box? I'm assuming you can't fit 2 10s in a door.

Just wondering how you did your install.

Two 10s per door sealed. I don’t have any pictures on my phone but I should have some on my computer somewhere.
