Sound Deadening: Dynamat/Ensolite project complete

[bbolton]

Thanks Jumbo! That's probably what I'll plan to do, I was going to try to deaden the doors this weekend and within the next few weeks/month I'll try to get to the floor. What did you use to apply your dynamat? Also, how much did you use? I'm looking at getting on bulk pack (I think it's 36 sq ft) of the dynamat extreme and using one of those wooden applicator rollers, would you recommend that? Thanks for the prompt response and the help!

I had bought 3 bulk packs of Dynamat Extreme on ebay for about $90 a box, much cheaper than the retail of $250 a box. I think ebay links are frowned upon here but if you want the links where I got them send me a PM. I used a total of 108 sqft (3 bulk packs), it doesnt go as far as it looks. Also look up RAAMaudio and take a look at his sound deadening. Looks like pretty good stuff and a great price. Thats where I bought all the Ensolite.

I went to Target and bought a small wooden dough roller out of their kitchen department for about $4. It worked great and you'll want something small cause you have aot of tight spots to get into, especially inside the doors.

Too bad we dont live close, I'd help you knock this out in a day.

I just swapped out all of my speakers with Infinity's and performed the dynamat extreme install. Having performed a few Dynamat installs, I've learned the tricks of where to place it. I skipped placing it over the clear plastic on the door as thick foam is already on the door panel and is more than adequate. I decided to place a large piece inside the door to add to the factory deadening material that's used sparingly. I also went up the beams between the doors and behind the rear door as well as removing the seat belts and placing some inside their cavities. I decided against using the additional mat used by jumbo as the factory stuff is already great.

The dynamat was enough to figure out that there is noise you won't be able to kill that stems from the windows and the dash that nothing can really be done about. I used 2 boxes of 9 pieces each and found that to be adequate enough coverage. I used all of it too, so a 19th piece would have been preferred.

I used 2way 6x9s in the front doors, 3way 6.5s in the rear, and 2way 3.5s in the dash (yet to install these buggers). I chose infinity due to their 2 ohm impedance which makes a 4 channel amp produce its highest amount of power (90x4 rms for my 475a amp). I have 2 kicker shallow mount 10s in the "ebay" box that I reinforced with fiber glass and recovered with a light brown fabric. It’s not quite my sand beige interior, but it’s better than the standard gray it comes in.

When doing the dynamat, I ran 1/0 gauge wire from the battery to the rear. I used the large grommet up under the driver side dash by making a star-like cut with 3 jabs of a utility knife with a new blade. It’s huge so it’s easy to work with. There are 2 sides to it, so you must make duplicate cuts on both sides. This is easy to attain my making the star cut inside first, and only a slit in the engine bay. From inside the cab, shove a finger through the star cut to make sure you can feel the slit from the engine bay (if all is good, finish the cut in the engine bay). They don’t have to be perfectly aligned, just good enough. I used paracord to tape to the 1/0 and shoved it through the hole from inside the cab to the engine bay. I made up a small cup of highly concentrated dish soap water to use to lube it up as it got pulled through so it wouldn’t rip the grommet out too. Worked like a charm and was able to perform it by myself. Help would have made it a lot easier, but it’s not required.

I have a 200 amp relay inbound that I will use to separate the 1/0 from the battery as I’m going to add a second battery in a toolbox in the bed. I will be replacing the weak factory “HD” battery with a sealed deep cycle of the same size. The battery in the bed will be a duplicate. I also have a 1k watt power inverter that I’m installing next to my amps to use whenever. I tailgate a few times a year and also find myself places that are short of electricity, so this will come in handy especially with a huge reserve capacity. I’m currently working with “changeip” to make a workaround to the weak voltage output of the alternator. It’s horrible and won’t charge deep cycle batteries worth a damn (13.8v peak!). He currently uses a POT switch with resistor to dial in a charging voltage, but I want so make a solution that has it pump from 14.5-15v constantly so I can keep those batteries charged. Toyota keeps it low so it preserves the life of the standard (did I add weak?) battery the truck comes with. I’ve killed it twice already just listening to my kenwood dnx7100 with factory speakers while doing work to the truck. It dies way too quickly and doesn’t charge worth a damn at the low voltage output of the alternator.

Yeah man, that would be ideal. Keep an eye on your inbox the next few weeks as I may PM you along the way! Thanks a lot for the help.

Mark, You were able to do 2 layers on floor, back wall, and doors with 108 sqft of Dynamat Extreme?

Hey Glenn,

Yeah, 2 layers just about everywhere. When I say "just about" , there were some places that simply would'nt hold 2 layers and a layer of Ensolite on top of that. Those spots were small and around the seat brackets and places like that where a tight fit was important. But other than that, yes, all the doors got 2 layers, and about 90% of the floor. I'm ordering another box to do the roof soon.

Mark - Thanks

[Jumbo Jet]

Youre very welcome.

My wife would kill me if I spent two weekends in my truck. Where do you get the best bank for your time. Doors? Floor? Misc?

I would say doors and floor. You have alot of road noise coming from below your feet.

Wow this takes forever! I've been at it for about 4 hours and am still finishing up the first door! This is my first time doing it. Man I wish I had more patience.

haha, my first door took some time too, but now that you know what to do the rest of the doors will go by really quick. That first door is always the trial and error door. The end results are well worth all the effort.

[PS-RagE]

I went without my truck for an entire long weekend when I did my sound dampening. It took at least 50 hours. Mr Jet here has done it twice!

[markramirez]

Alright, I feel a little better. My plan was to finish all 4 doors and install some boston pro 60's this weekend. I guess I'll settle for doing 2 doors and maybe installing the bostons. Patience grasshoppa.
