I'm planning on adding damplifier type sound deadening to the interior while I do some repair and replace. Has anybody tried putting roll on type bedliner over the sound deadener?

Bedliner over sound deadener?

If you are looking to get additional dampening you might try a product like spectrum or sludge from secondskin. I can't see a problem with adding bedliner over it though.
If you plan on doing bedliner, why not make the bedliner extra thick and not worry about the sound deadener?

This is what I originally had in mind, but after reading up on sound deadener mats I started wondering if there was a better way. It wouldn't see the abuse of a pickup bed and it's designed to bond to wood, metal, what ever. Sound mats have a foil face, so it got me thinking.

i used herculiner on my roof rack, and thats what i plan on using for the flairs, i was pleased with how it covered.

How about feed back on how well liner functions as a sound deadener?
Better/worse than stock carpet.
Right now my cargo area is covered with reflectix foil insulation. It has zero durability, but it was cheap, available, and better than bare metal.

Bedliner won't be nearly as effective as a sound dampening material.
On my new truck I'm planning on bedlining the back as it didn't come with the 3rd row seats. I'll go over the factory sound dampening material with some Second Skin Spectrum, then go over that with the bed lining material. My concern with going stright to the bed lining material is that there would be a lot more noise and that it would be too soft. Spectrum once dried is extremely tough and resiliant (but it's not completely solid, it's feels like a very tough rubber/plastic).
If you go over something with Spectrum, you'll want to let it dry for an extended period of time before putting anything else on top of it. Second Skin recommends 30 days IIRC. In my experience using it I'd probably give it about a week, being summer and all. I would wait 30 days if it's raining and/or cold.
I can highly recommend Spectrum, I did it in the Mrs. rig and it made a huge difference. Easy to apply too, and you can get into cracks and crevices that traditional sound dampeners wouldn't be able to.

bedliner material would be to soft?

Ebag,
Thanks for the info. I went to their site and did some reading, and this looks like a much better method than trying to get liner to stick to the matting. Now I know what to do I just need time.

Depending on the type of bedliner you use, yes.
Remember it's going over the factory matting with lots of little cracks and holes. The factory matting is pretty soft, and I could see the bedliner flexing and getting torn eventually.
Granted if you put it on thick enough it shouldn't be a problem...
Anyway for me the sound dampening properties are just as important as making it bulletproof.
cody, not a bad idea
That's not a bad idea at all, I'm just not sure how well Spectrum and a liner would mix. They may not mix at all, or may seperate while drying. Would be a bummer to do it and then have most of your bedliner at the bottom, and your sound dampener on top. 
That being said, I would feel comfortable with using spectrum as a liner for an extended period of time. The stuff is tough, they designed it with undercoating in mind so it has to be able to take abuse.
