Got my hands on a FLUKE TiR thermal imager for the day so I figured I do a little testing on the heating and cooling of my subs/amps. So Playing my system full blast for about 4 1/2 minutes (usher-daddys home off decaf's zip 14) The main frequencies peak at 39hz, 38hz, and 26hz. Subs just starting to get stinky(clipping a tad to see how hot I can get them) Subs are in a 17C.F C-pillar wall after displacement, tuned to roughly 28hz. Subs are (2)18" AA Mayhem D1, amps are (2)Colossus XXV clamped at 2,800 RMS each. First image was taken within seconds after turning down the volume to 0. Shows the center(dustcap area) of the sub being roughly 132 degrees, and just next to the dustcap 108 degrees. Second picture was about ~15 seconds at volume 3/4 way to full tilt. Notice about a 10 degree drop in 15 seconds. Another ~15 seconds later, volume still about 3/4 way to full tilt... Not bad, these subs are cooling off nicely! Now to the amps, Testing on these were done while system was up full tilt. Notice my mids amp on the bottom left getting hotter than the subs amp? Roughly 105-106 degrees. Sub amp seems to be about the same, 105 degrees now in 2 spots(looks to be location of the mosfets)

You are correct on that, at least in my eyes. I know you should have gable vents in your attic, or some sort of ventilation. And a vent system in your bathroom to remove the moisture in the air when taking a shower. But as far as around the windows/doors you dont want any leaks, especially in winter in a cold climate. At least this is how I feel about it... I'm not too knowledgeable in this field though lol

One of the things they are made for is to see through walls thermally for insulation and stuff. This one retails for roughly $9,000 too lol

So far they are doing good. Clamped them at 2650 watts RMS with box rise to 1ohm and voltage dropping to 12.7v. And thanks Oldskool Should have more videos up after the next show on May 2nd

First and foremost big thanks to TMH for designing and building the wall(I helped but he did most) lol Tested at 150.4DB @ 31hz sealed legal on TL. Truck now peaks at 30-31hz. Also did a 151.8 outlaw...

And here is a video... http://www.youtube.com/watch?v=DKejoVshwC8 Here is a video of some testing we did a few nights ago before the cops crashed the party... lol #'s changed to 150.58@38hz(did a 150.8 but wasn't on video, so we will go with a 150.58 lol) Here is a flexx video and showing off some oldies

Wow, it's been a while lol. Some updates:) I changed the amps(2 crescendo 3kw now) and sealed around the wall(still needs trim panel put on) It is now 152.5@36hz sealed legal Had first show of the season this past sunday(4-11) and blew a sub before qualifying Stupid clipping lol Actually burnt 3 of the 4 tinsel leads on one coil....

Still have to install the rest of the mids/highs in front doors, waiting for it to warm up outside to work with the fiberglass...

Thanks! It's going to be sealed off soon.

Thanks. I threw up a build log post... The_dude/TMH's build log... - SSA Car Audio Forum

Looks nice! Tuned in to see the new build.

I did break a shock(heard a big pop noise and fluid was leaking out) So I bought these: Monroe Sensa-Trac Load Adjusting Shock Absorbers And these: LEAF SPRING HELPERS - JCWhitney Engine I have a 5.0L V8 so it should be fine on that end. All in all, take off is a little slower but other then that it's all fine now

Thanks for the compliments guys. TMH did a great job on this build/design. I also plan on being at finals this year if they can ever figure out where/when it will be lol

Dunno why we demo'd driving, lol. I think it was just more convenient... Thanks for all the compliments guys! All we have left is to seal off around the wall, make the beauty panel, fiberglass inside the box, fiberglass some more mids in the front doors, and pretty much done lol. Here is a video of some testing we did last night before the cops crashed the party... lol

There is an excursion vid of my 18" mayhem... It sure does like to move and get low lol Hell I like it so much I just bought a 2nd one for my new wall build.

So my dad and I are out in the backyard digging the trench to run the conduit/wire to my garage for the 60a feeder. While digging I hear a loud metallic "crunch" sound from my neighbor's home, so we look over and see someone trying to back out of the garage with another car that seems to be stuck to it. He pulls it back into the garage to reveal the fail. We couldn't stop laughing and I had to grab some pictures. I think this is the funniest thing I've seen in a while lol.

Here is a little woffer porn And here is the MAYHEM opening the sunroof shade....

1. Post your SSA user name 2. State that you qualify to the terms and agree to follow through with them as they are written above. 3. Post a description of your car and system 4. Post how you plan on helping promote Second Skin including the other web site you will post your build log in. (Rembmer build logs and videos are always better for us) 5. You must tell us something about yourself that nobody on this forum knows about you --------------------- 1. the_dude 2. I qualify I believe and agree. 3.1997 Explorer Limited V8 AWD ~(new set up for next year)~(2) 18" AA mayhem subs, (2) Hifonics XXV COLOSSUS amps, 12 panasonic batteries, alpine H/U....etc...Currently has (1) 18 and one amp and 6 batteries. 4.I will post pictures/build log on this, and the other 5 forums I belong to(3 of which are audio forums, the others are car related) 5. I only listen to rap in my vehicle because I like the bass.

I'm running a Hifonics XXV COLOSSUS to my 18" MAYHEM(I know its not BTL but its close lol) and the sub seems to love it. Im doing a 146.7 on music sealed legal on TL...and 149.1 in the kick with drivers window crazked open... And that amp can be had for about $600 shipped.

Why don't fat women look feminine?

As far as I can remember they should be universal, I believe you would chose when you order your recone kit.

Add me in for another vote for the 12" Havocs... I've heard the 15" havocs before and like them.

That looks like it's going to be a beast.

Damn 6 posts short.....
