Need help with truck rattle when stereo is on.

Just installed this package and wanted to soundproof the bed undercarriage. Been getting conflicting ways to do it. I was told to rhino liner it by one then I was told to dinomax it by another and this and that. I want to get the rattle out without taking the bed off. Any suggestions. I have these 4 8 inch kickers, 2 15 inch kickers in the box and 4 6x9 kicker mids. I put a separate bass volume control in so I can control that end and it works but if I want that thump my bed goes to rattling something awful. Anyone out there that can give me a correct cure for my problem.....

 

Not trying to be a dick but what's the purpose of the speakers on the outside of the cab?

 

OP, with that sound setup (and I'm assuming a buttload of wattage supplied to those speakers with amplifiers), you will NEVER get rid of all the rattles. Spraying underside might help, but there's lots of parts to the bed. Maybe narrow down the rattles and go from there.

I'm guessing since OP appears to live in Florida, this is for outdoor beach parties, etc.

 

Check the fender liners they rattle

 

Maybe don’t turn it up.

From you post, sounds like the speakers are doing their job, moving massive amounts of air creating vibrations for you to hear.

 

That's what I'm hearing, always gonna hear a rattle somewhere. If I could get rid of the bulk of it I'd be happy. All about the sun, surf and sounds hear at the beach.

 

Thanks, I'll look into that as well.

 

What, dont do what..... wwwwhat........ K, didn't hear that........ LOL...
