Thanks everyone, figured someone could usem for wallpapers

original original Anyone else got some dcon, icon, xcon, love?

Impressive

Doesn't sound good, tuned in for details

Then I hope it works

heh, looks like the stuff work wells. Curious to see once everything is done, if 15xdB+ rips it apart or not.

"Oh yeah, I like this glue"

Daily and TL don't make sense. If you can't hear the difference why would you care? No. Not a rule of thumb that is viable. Vibrations in phase and matched in frequency will increase the dB's, out of phase enough to be deconstructive will decrease dB's and ones at different frequencies could do either or nothing. If someone had TL results with only tenths or a dB gain, then it likely wouldn't be worth it. But if someone came back and gained like 4dBs, then wouldn't that be an audible increase in output? But I guess it's immaterial since every vehicle will act differently. Either way, if someone has any results they'd like to post, it would be much appreciated.

i have heard this a lot lately... could you explain ? sorry for the thread hijack OP You only need ~25% coverage in the center of the panel to control panel resonance. This is what you would use cld tiles for... Now mlv and ccf, your going to want to pretty much cover everything up. MLV (mass loaded vinyl) is used for sound deadening, so cover everything you can with it. The CCF closed cell foam, goes in between panels so that can't rattle against each other. So doors for example: Put a few cld tiles in spread apart across the door sheet metal. This will add some rigidity and help stop the sheet metal from flexing in and outward. Then cutout a layer of mlv to cover the whole door, use adhesive or velcro to hold it in place (heavy stuff). Lastly, add a layer of ccf so the plastic door panel doesn't rattle against the actual metal door.

I believe 53hz.

But when the amp is off, does the circuitry that the positive and negative terminals are part of have any resistance?

Is it possible that the drivers could be 0.7ohms in total, and 0.6ohms is from the amp, if he didn't disconnect the speakers from amp when testing. Either way OP, do as Shizz said

Yeah I won't have my car rattling like soda cans when I'm driving it down the road. I'm just gonna install subwoofers, play'm see what all makes noise and flexes, then go from there.

How long have you driven with the new alt? Try letting the car idle for 10 minutes, see if the computer corrects it.

They will be worth the wait.

Crazy flex man. Gotta brace that back panel

There is a catch, vegas or virginia?

Perhaps interchange ports?

Just ship your door to Fi car audio's address...

Yeah I've seen those, I just figure the amount spent for one, could pay for more sound deadener and bracing material I think I'll just keep a log of everything I've done, and dates and meter results from all attended shows. Depending on show dates and after I get a new alt in, I may shoot you a pm, thanks

Thanks for posting. Yep hatchback. I know sound deadening won't be a audible increase or decrease in output, but perhaps roof, door, quarter panels, hatch area, and pillar bracing could be noticeable. Bracing would entail steel strips, wood, epoxy, and expanding foam. But it would all be under the plastic panels, so aesthetically you couldn't tell the difference between stock and it. Wish I had a tl or spl meter to record my results

Has anyone done any TL testing with a vehicle before bracing and after bracing? Mainly looking for daily driver type results. I've added sound deadening to my vehicle (2002 volvo v40), in hopes of getting rid of rattles and other annoyances. I haven't applied any treatment to the roof yet. Once I have the subwoofers playing, I'll be able to tell if / how much it needs to be deadened & braced. I'm just toying with the idea of bracing the roof with 1/8" steel strips, bracing door sheet metal, and other flexing panels across the vehicle. So not doing any stripper poles, or bolting shut doors. Just curious if it would be worth it, if there would be an audible increase in output. (When I say this, I'm also aware that sound deadening can sometimes lower spl. But I'm trying to make my vehicle free from rattles and as loud as possible. I don't believe power is key) Thoughts, tips, any input? Subwoofers are 2 15" xcons. Amp is a saz3000d.

Sounds pretty serious, as if the 4500d wasn't enough

That is some Insane flex. So worth the wait Your wiper doing the tango. Just imagining the amount of force that's pushing the doors in and out, unbelievable.
