I'm about to relocate my amp back under my rear seat and while I'm taking it off the rear wall I'm thinking about putting some eDead back there. Will lining the rear wall and all four doors with eDead 80 actually make a noticeable difference or is it really only necessary when there are high power amps putting many watts to door speakers which in turn is causing the panels to buzz? I've got a little buzzing in my front doors now so I think it will make a difference. Right now I'm just running some replacement speakers off the factory deck but in the future I'm going to amp the front speakers and put in a nice set of components. I'm putting in a JL13TW5 this week if that matters at all.

 

Yes, it will make a difference. not only will it make your speakers sound better, but it will make your ride quieter, and your truck stay cooler/warmer.
