Finally got around to editing and uploading a few videos of my new setup

http://www.realmofexcursion.com/videos/Alpine/typer12.2.wmv

They cut down the quality even lower but you can still make it out alright.

*Might have a higher quality vid uplater*

Playing test tones (23-40hz)

is it just me or is that baffle flexing like a mofo?

it does look loud though:thumbsup:

 

[Rawr-DQ 10+ year member]

Baffle?

 

[Rawr-DQ 10+ year member]

Oh...yeah. Don't wanna break a brace! //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I need to brace it bad...flexes like 1/2+ inches sometimes.

oh shit lol, u built that nice box but u don't know what the baffle is? its the front and rear of the box. it looks like the subs aren't screwed in

Baffle?

It's the flemsy little board you mounted your woofers to. flex = loss of output.

Needs more bracing. try flush mounting over them for a double baffle.

They're screwed in, hard to get to some of them with a drill but I managed.=...I had a little brain fart...kekekekeke.

But, Acutally, it is the front plate that divides the front and back of the sound waves...

that would solve the problem, yes, BUT that box is extremely cramped as it is and depending on the thickness of the mdf (if it's 1", i dunno if that'd even work). i would just use some triangles on the inside to up the rigidity.

Thats a pretty good idea however, I don't think I could be able to add another piece of wood there, it simply won't fit.

I do relize that I'm losing power because of it, just haven't gotten around to adding a brace.

I'm thinking of putting in two pieces of .75" mdf together (scraps) then sliding them b/w the port and baffle. Probaly gonna end up screwing in one side into the baffle then gluing both sides.

Looks good man, bracing would be good.

Also does you voltage always drop like that? I didnt see it get over 12.8v, was the car off?

exactly, so just do some interior bracing

you're not losing power //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif unless u mean that since ur losing output u need to crank it up more. a simple bracing system should aid in better output overall.

I did do a double baffle on my old boxes though, those suckers were small and didn't flex at all, but they had .7 cubes each. That was with two subs, 4 with 2 each mounted together once.

 

[Rawr-DQ 10+ year member]

Power as in, the flex allows it to give way and the output goes down...Losing SPL, power of the sound waves I suppose.

I'm just thinking different.
