finally got to my first Iasca competition... best sound score there, just a couple little install details to work out, and I'll be top three at world finals easy.

 

allright , as far as sealing the doors that is a good thing but you are going to run into a severe headache if your window is ever damaged and needs replaced. I just used the dynamat extreme and double layered it to cover the hole. it does the job and can be removed easily , by riveting or welding in metal panels it would be a much greater challenge to remove them. What you are doing is great if your car never sees the real world but chances are that this would not be desirable for a daily driver. What did you do to drain the water out of the door? did you leave the factory holes in the lower jamb?

congrats on the IASCA comp. and I would love to see some photos of the install and tweeter placement.

there is a lot of very stiff competition there and people with more money and time than sense, I have entered a few usac competitions but have never delved into the IASCA scene.

good luck with it all!

post some pics of the doors I am intrigued.

 

The car is a daily driver, and I agree, the windows could be a problem, but if there's that big of a problem, it'll be cheaper to buy a new door and re-deaden it. I left the factory holes in the bottom of the door to drain water out, 'specially since my componants have paper cones hehehe.

my next Iasca competition is this weekend, and I've made some big improvements in the sound, and the install. Usac is much more stringent in the isntall portion.

The doors are solid, with the sheet metal, and then the 2 layers of eDead V1se (the thickest mat you can get) I'm thinking of putting an aperiodic membrane in the door to increase my midbass, which should completely eliminate the need for processing, but I'll be acquiring an alpine PXA-h701 in the very near future.

 

you cant elliminate the need for processing unless you run a full range system using high qualty passive crossovers and at least a 3 way speaker config! Even then some recordings are stupid andrequire taiming! Processig is your friend... the greatest studios in the worls use it your car shourd too...

 

actually, the greatest recordings, and the most award winning studios use no processing. Telarc has won hundreds of awards for their recordings, and they do them all the same way, big room with a high ceiling, 2 high quality mics, straight into a 2 track tape recording unit, and they sound amazing, try listening to some on a high end home or competition car system. any recording that requires taming is poorly done, if you do an ocilloscope analysis on most modern recordings, they're clipped all to hell because the engineers today don't have the skill of the engineers of years past, they rely on the processing to do what used to be done with mic placement and other techniques.

I went to college to be a recording engineer, and I've worked in studios, the good engineers do things MUCH differently than the rest.

 

OK we will have to dissagre on this one then since I subscribe to the school of thaught whick also governs live sound stage production for huge concert rigs using hundreds of thousands of watts!!! Have you seen the number of processors used in these applications! and on top of that the system requires constand monitoring for transients and such to prevent driver damage and over load!!! You clearly are not pushing a high power car system! but nothing is wring with that! as long as it sounds good to you!
