it should be. most cars' bodies have a weld somewhere connecting the whole car together, some have insulation/rubbershit in between the body and chassis. just try the trunk, if it doesnt work try somewhere else.

Try and it and see if there is any noise introduced. You can also test it if you have a DMM.
