RATTLES from sub

[fourthmeal]

Wow. thanks for the very in depth approach. Maybe a little bit to technical for me even tho you spelled it out as much as you can. i appreciate it very much and honestly think i should just wait until i do have a bit more money. i have a jvc kd ax2 deck in. maybe ill just stop the rattling for now. cause i think what mim looking for is gonna cost me because i dont want my subs and amps to be huge and noticable, id rather them be subtle and BUMP.

I understand. I don't build SPL systems, I build SQ systems. Sure they get loud but they never lose their composure. Good equipment doesn't have to be big, you just have to know how to get what you want with the least amount of space loss. On the older Escape style you have a spare tire that isn't there on the newer models, so things are different for you. you might want to stay tuned to "The J's" system I'm helping him put together. Fully stealth, just like your model year too.

Deadening will run about $180 or so, complete. Register with DIYMA, and you'll find that ANT of Secondskin has put together a promo with his new black Damplifier deadener product at a discount. That will run you under $100 and do 40 sq. feet...pretty much the whole car and then some. Remember with deadener like this, full coverage isn't necessary...roughly 25% coverage is good, and you focus on the non-curved metal of the car floor, doors, and side panels. Curves are stronger so there is no resonance there.

Next, in the same site order up some closed-cell foam to go over ALL the trunk, and the doors over your deadener and the metal. You want to cover 100% where possible. This should be attached with spray adhesive...strong stuff don't go for crappy Home Depot 3M spray it just doesn't hold.

Next, go to the http://www.sounddeadenershowdown.com website and order up some mass loaded vinyl, enough to cover at least the rear trunk floor. You can also pony up for enough to go into the doors and tailgate if you want. This step is optional but it pays great dividends in road noise and rattling.

Done!


edit: Oh yes, pick up a roller to roll on the deadener. You'll hate life doing it by hand alone.

Hey guys, I have an 09 Escape that I recently built a sub box for. Unfortunately I don't have any pictures for you guys, but it rattles when the volume is really really low. I had an 04 Escape before this one that had 2 subs and no deadening that didnt rattle as bad as the new one. Being a college kid, I dont really have the cash to properly deaden the entire car or much of it at all for that matter. Does anyone know why it might rattle really badly without turning the volume up much at all? Thanks for the help.

Sub box leaks??

[SteveT]

That can cause rattling? When I built it, I sealed it with silicone sealant so I dont think it should be leaking.

Define rattling. Because a leaking sub box makes for a noisy box. Also the sub could be rubbing its voice coil.

[SteveT]

Well, I looked up what rubbing a voice coil is, and I do not think that is it. I have never overpowered either of the subs before, they have both been run off the the 500/1 amp for their life. I will test my old box and see if I get the same sounds. Thanks for the input fourthmeal.

I installed my old box and there are absolutely no rattles. How could a box make so much noise?

Air leaks can do a whole lot. There's a lot of pressure being built up and then instantly reversed in a sealed speaker box, up to hundreds of times a second.

I've had the license plate rattle, bolted the bottom down, now the door rattles too and have no idea. I've also busted a couple of license plate bulbs too! haha

On my car, I noticed that the back windsheild motor cover that is inside the window was rattling on the window. Used a little velcro tape(soft side) and cover back side of the panel. No more rattle.
