Any tips for rattling after subs installed?

[SGT_slap_a_hoe]

Car rattles a lot, way more than I thought it would any ideas on how to tone it down?

remove sub would be easiest…or dyno mat, but you might be doing most of the car to get it to stop.

Mine rattles too. I just turn it up more ()=)

I just added a sub too, I get a nasty one that sounds like its coming from the passenger side rear deck. I saw a thread where someone said to stuff some type of padding between the deck and the mounting-point. I disconnected my door speakers so my window switches dont rattle as much but they still do. I think someone said the dealer puts padded tape to fix this. Going to probably do my trunk too.

Best thing to do is to try to isolate where the rattle is coming from. Then address it with the proper material. That can be Dynamat, MLV, 3M automotive insulation, etc. If you take a look at the build logs of some folks, most choose to just add some kind of sound insulation to the rear deck area and some felt/foam to the 3rd brake light. That seems to address most issues with rattling in the rear deck area.
