how can i stop my bass rattling my car?

Question

its not particularly loud and i dont have any boy racer speakers in it but it still rattles the metal when i turn the volume up, its a saloon so its the boot where the metal is

Answer 1

Your problem you have with rattling is very common once you upgrade to subs, there are couple products out there that can reduce rattling alot they are called dynamat and brownboard, they are usually found at your local electronic retailer if not ebay. That should cut your rattling down in half, and try and move your subs around if its a box, sometimes it'll help. If you have powerful door speakers, then i definently recomend dynamat, its a self adhesive mat and has sound damping material in it it'll stop the big surface from flexing which causes rattling. My truck had so much bass from 4 alpine type r and running about 4000 watts of power and it pop'ed the windsheild :)

Answer 2

Bass by its very nature is a vibration so when the sound waves hit a surface that surface is been vibrated. Kind of like drumming your fingers on a window. Or getting a empty drinks can and flexing its surface.
You may try to see if there are any sound proofing materials that you can cover the area that rattles. A layer of foam may quieten down the rattle. Something that breaks up/absorbs the sound waves before they hit its surface.
Or a more drastic measure would be to solder a grid onto the surface of the boot so it doesnt flex to dampen down the vibration.

Answer 3

You have something loose in the vicinity of you speaker, or the structure to to which you have mounted your speaker is inadequate to support the force generated by it, and it is flexing as the bass notes play.

You are going to have to try to beef it up in the area of the speaker mount. You might be able to cut a plywood "doubler" whose ID is such that the speaker will sit flush, and whose OD exceeds the OD of the speaker by an inch or so. Set your speaker through this, and then tie down. Use 1/2 wood or thicker.

Better yet, build different enclosure out of 3/4". It will be heavy enough to stay put and not rattle.

Answer 4

I have the same problem but I have a 29 year old car :p the weather stripping is half gon on the trunk and that's why mine rattles to the bass maybe try some extra weather stripping so the trunk can have a tight lock? It may sound dumb but it's worth the try

Answer 5

If it rattles and the volume is not that loud, then I would assume it's because you have it set right on the sheet metal. Try padding the base of the box and then see what happens.

Answer 6

Insulate the trunk. Put a lining on the inside of the trunk lid, etc. Next time you want to jam out, get a better quality vehicle.

Answer 7

Wadding should be placed inside, and you should also check the rear window and boot seals. Sumtimes da window vibrates

Answer 8

stick sound proof insulating pads onto the inner panels and a bit of rubber behind the number plate.

Answer 9

Find and cushion everything that rattles

Answer 10

Two ways. Either cut the wires or turn down the volume.
