Stealth, please chill out, name calling and being combative is not how we run things here. There is nothing wrong with a spirited debate or disagreement as long as people keep their heads and use factual information and sometimes have concrete examples to back up their statements. Take Impious' (Brad) posts in topics of disagreement, he goes point by point and throughly addresses each thing with experience (not just saying he has experience), the science or laws behind things, and sometimes factual calculations and examples to support his argument. I am not at all saying everyone needs to be as knowledgeable and skilled as Impious (if that were the case we would have less then 10k posts on here ), but we strongly prefer people take a much more scientific approach to each and every topic or question. THAT is what really sets the SSA forum apart and above all other copy-cats, plain and simple. People get pissed at ///M5 (Sean) all the time, but he is extremely consistent on working towards taking a logical and scientific approach to every problem or topic presented, that is the only way to really head in the right direction to reach the desired goal, what ever it may be. This above quoted post is very inaccurate. Install includes the enclosure/box and all equipment. The vehicle's resonant frequency will have a great deal to do with the end result. The positioning of the box (also part of install) will effect the end result. The gain settings, the HU settings, crossover settings, processor settings (if there is one), sound deadening applications and amounts, port and cone firing direction (also install), and so on. In reality, there should be no one single most important thing. Every aspect that can be controlled, with in reason and/or budget, along with how they effect each other, needs to be taken into consideration when working towards extracting maximum performance regardless of the focus or purpose of the install. Consider in the SPL game where people with far lesser expensive and lower power installs are putting up just as good if not better numbers then people who just think >> big cone + big amp = autowin. The first group of people are taking much more into consideration and using all parts they can to their advantage. All of this has to be combined with testing in the particular vehicle/install.
