rattle underneath the truck

[Itscortez]

Hello everyone I am new here. Anyways I have a 2006 ford f150 FX4. I recently got a sound system , 2 12' kicker with a bedliner spray box. I don't have the bass up to high but im getting a bad rattle underneath the truck! Woundering any tips? Was thinking of using peal and seal (you know what I mean) thank you and god bless.

Welcome to the forum. Could b the shroud around your exhaust making the rattle. What u can do is play your stereo and walk around the truck to try and find the noise. Good luck. Let us know how u make out
