Hey guys i own a CPO IS 250 AWD, and recently i noticed when the sub is cranked i hear a clinking sound, i check under the sub in the trunk and directly heard a metal clanking sound. Does anyone know if there is a DIY to safely fix it, as i love the stock sound system but cannot tolerate this clanking sound. thanks alot guys!

 

Do you have ML? They are known to blow out. I had mine replaced under warranty recently.

 

take it to the dealership and have them check it out.

 

it is not ml, but i have navi with 7.1, i just purchased the car recently nd it has alot of miles left warranty wise. So they will replace any faulty part? thanks guys

 

anybody? thanks

 

Err did you think of taking it apart and seeing if maybe something is loose? perhaps it is the subwoofer itself. I think there is DIY for replacing or taking out the subwoofer.. i saw it somewhere.

 

I would purchase that 3m type foam that is intended for window insulation. It can be bought at any hardware store or Wal-Mart. It comes in a roll for about $3-$4. Pull out the trunk material and insulate contact points. It may also be a loose speaker bolt (rare).

 

Getting to the subwoofer under the rear deck is a pain. Take it to the dealer and let them fix it. It's covered by the CPO warranty.

 

thanks alot guys, appointment is made for this monday. I tell ya guys what happened, and see if i can find out for anyone else who has the problem.
