First off, if they missed the thread above them what makes you think they will get this one.
Second, the search function sucks donkey shaft balls deep
And thirdly the only way you will ever have an impact on the repetative thread are good fact based stickies that are compiled by the mods so that they are not riddled with 50 pages of bs and 1 page of myth dispelling facts. And you will need one or two for each area to cover each aspect of auto sound.
Another thing that you can also do is set up a seperate area for all the "is this better than threads".
But again because of the nature of this hobby your only real hope is alot of fact based stickies. Maybe if all you guys get together and build a couple of imaginary systems (an add a woofer system, a mid level system and an all out super system). With lots of links to bcae1.com which has helped me imensely.
Now I know you ask youself why TF should we do this, they need to learn this shyt on their own. How long have you been on this planet, you should know by now that most people are sheep and that common sense is not so common. This is one of the few choices you have that will actually have an impact.
Just as an example, I was looking into eq's recently and I had to go through 4 pages of crap before I got the single post answer (from squeak of course) that I needed. If this were in a sticky then I would have known it already as the sticky would have covered it and all the other threads that sprang up after mine about the same subject would never have been or would have died quickly with a "read the forum stickies".
