hey,
boy you are really the guro of all things wood. your theory works, in practice your argunent has alot to be desired. I am a master carpenter with 20 years experiance, I know what I am talking about. I can build you a box that has nothing holding it toghther other than the wood itself and some cheap *** latex caulk for the interior joints, I will shipp it to you for you to do your tests to, I defy you to destroy it with any woofer and Amp combo. I can also build you a box that is pocket screwed and Ploy glued, and I give you the same challenge.
these guys that are conversing with you have a good grasp on how to get it done, they may or may not have all the skill you have, and they almost certainly don't have the post count, however they do have some skills. I think you need to get off the high horse for a while. without a doubt unless you have proper joinery with massive amounts of wood to wood contact, there is more than enough room to argue that PLOY glues and construction adhesive have major merrit.
The construction industry was introduced to construction adhesive (aka liquid nails) not because wood glue dosen't work, rather in the real world the joinery between materials in the field is less than perfect. there for a high viscosity adhesive has found itself a place in the industry. Unless you have a really nice table saw and the skill to use it, you probably are not going to be able to get cuts that are considered proper joinery, the joints will have voids in them that will be filled with standard wood glue, which is very brittel. when you have these kind of juints, they will more than likely fail under the pressures of car audio. there are products that address this lack of presision (POLY glues ...) If yo have good cuts, that have been cleaned, you are correct that wood glue is superior. I do however question how many cust are "good"
