Should consoles touch the enclosure? When they do, how do we perform the string test? In the past we've looked inside the box to varify the enclosure doesn't share the same airspace as the console.
If consoles remain attached to enclosure, would that be considered a brace?
Please comment.

They should not touch, and if they do they should be considered a brace.

the way I look at it, is if you mount an amp to the box, it is included as part of the box, so why would this be any different? The way I see it is that if they are connected then the enclosure is WAY past the pillar.

I say we require there to be a minimum distance, like 1/8" between the two. Something large enough that you could pass a string through for the string test.

just wondering why it matters if it is a brace? it is not connected to the roof . They are not used to add more box volume. If verication of the string test is a problem. Then make sure you can look and see that the sub(s) are behind the door jam. It has not been a issue since 99 when it first started appearing. Why would it be a issue over 4 years later.

I say at least 4" from the walls , if not it is compartmentalizing the pass. side there is ussually a 4-10db difference from driver side miced to the pass. side. Umm . maybe new rule micing car , how about since new pressure sensor works so good and sticks to window , no need for mic stand , lets meter both sides and average kind of like in SQ listen to driver and pass. side , that could eliminate the purposely loaded the pass. side up. what do you think? that would make it fun!! and fair ,no one has to rebuild for that ,the meter just get stuck up on both windows!!

I agree.I haven't seen where it is causing a distinct advantage to have it attached from a structural standpoint. If that was the case,then maybe the console shouldn't touch the dash near the windshield either! How well would that go over?

That string test is quite is to do if you drill some hole in your console and use pen laser beam to prove that string test is ok. If laser beam can go throw car and don't touch wall or subs then test is ok. I hope you can understand...

yes, I do understand. But if you follow and perform the current rules:
Compliance with this rule may be verified by using the following test: Two judges position themselves on opposite sides of the vehicle. A string (or wire) is passed through the open doors of the vehicle. Both judges pull the string so that it is taught. Next, the judges move the string in unison so that the string slides along the trailing edge of each judge’s respective doorjamb. If the string does not touch the enclosure (or loudspeakers), then the test passes.
by doing exactly this, a pen lazer wouldnt' work.

Why should them?I think as it is now it is good, just be able to demonstrate it is not communicating airspace with the box!And why bracing, it is not connecting the roof and the floor toghether!

One thing I thought about after making my intial reply...
What if the enclosure is set back (from the trailing edge door jamb) by six inches. Even with the 1/8 distance, the string test would still be obstructed. The only way I could see this as being an option, is to not allow any part of the console to extend past the rear edge of the door jambs. Since I do not agree that the competitor should be limited that much, I will have to change my response to...Leave things the way they are now.

Maybe the string test rule should say that nothing interferes with the string test. When I say nothing, I mean console, brace, dash, floor, roof. Just think of how the extreme vehicles will now resemble cars!!!

I like it. Also include that the "normal" seating arrangement of the occupants must not interfere with the string test either (basically you must be seated in front of the doorjamb).

I totally agree, no part of any console or person should interfere with the string test. Leave 1/4" if you have too but it should not touch.

Exactly why are we allowed to modify the door jambs? I say that the string test should HAVE to follow the original sheet metal down, the only modification to the jamb should be to move it back, not forward.
I have seen complaints about how consoles wont allow string tests, but what about door jambs being built forward? They make it MUCH harder to determine if A sub is too far forward or not. Its fairly simple to look at a sub from the stock jamb to tell, but with the built out jambs, its nearly impossible in some cars.
Why complain about consoles inhibiting string tests, if the Door Jamb can be moved forward for sealing purposes, TOTALLY prohibiting any string test at all?

If some boby wants make that "string test" in my ext car only way is used pen laser and shot throw build out doorjam to another side doorjam. There is two litlle hole in doorjams so it is possible.
