I know there are a lot of different trains of thought pertaining to car audio. But the two primary camps are SPL and SQ. I'm kind of in between, maybe leaning towards SPL myself, but that's a whole other thing.
So I was over on another audio forum, and their is a straight up SQ guy, who makes a lot of negative insinuations about anything to do with SPL. Like if your not an SQ guy, your stupid, childish, etc.

Hmmm. I dunno.... I don't feel that way about SQ guys, even if I lean towards SPL.

Kind of reminds me of fly fisherman who act like, if you really want to be considered a real fisherman, you have to fly fish... Really ? Well I have no problem with fly fisherman, and consider them to be no more, or no less a fisherman than I am. But not all fly fishermen feel the same the same about general fishermen.

Hmmm.

Well..."real" SPL doesn't even use music, so an SQ fan, who got into it so that they could enjoy their music even more, wouldn't really understand the point of just making noise.

I don't know. Just like your fisherman analogy, that's how people are, they think that whatever they chose must be the correct way. People have a tendency to think in binary, and create a competition where there isn't one.

Most pure SQ types likely have more budget, and also have more things to be concerned about than SPL numbers... so it is not surprising to have them look down the nose at SPL.

Given that many people like subwoofers with distortion, so of reinforces the divide, and the concept of in group out group mentality seems to be pervasive from politics to audio.
So social signaling is a possible reason.

You seem to be headed into the blend of SQ and SPL. And my perception is tha you are headed from SPL --> SQ. I think I more on the SQ --> SPL trajectory.
An SQ system that can do SPL is not bad, and we are likely to meet in the middle.

I suspect that the person you are referring to make not even be able to intimate the reason he does it.

TY guys. Holmz yes, you are exactly right. As it stands, I'm making a LOT of sound in the truck.
So now, I really just want to dial it all in, and clean it up. With a DSP. A new 4 ch amp. An upgraded alternator, and a few extra batteries plus maybe a few caps... Or a little lithium... Haven't decided.
I mean, I could see spending another $2k on it, without adding any more speakers, or any more power.

So yes, I am headed a little more towards SQ, but will never be a hardcore SQ guy (even if I could afford it). Nor can I afford to compete with the hard core SPL guys.

But anyway, I respect anybody who really goes all out, on either side of that camp, and puts in the time and $$$ to create something special. It doesn't have to be exactly what I'd build, for me to appreciate it.

One reason I suppose I don't fall with the SPL crowd is that every SQ build I've done has gotten more than loud enough for any listening I would ever want to do. You can design a great SQ system, and not have to compromise anything to still reach uncomfortable listening levels. There's a weird misconception that SQ builds don't get loud. I don't understand builds that shoot for higher SPL than a person in the car can stand, except pure SPL builds intended to be metered at dB drag races, and other competitions like that, and that's a different hobby altogether.

TY Gijoe. Loudness is very subjective, and hard to really get a good reference of.... unless we were all running around with a term lab hooked up and could say, "well I usually prefer about xxx Db's" :) I often do a lot of my stereo listening in my truck, by myself. And I think a lot of the time, I don't realize how loud it really is. But then sometimes when I have my GF with me, I will be playing it lower than normal, go to say something to her, and can barely hear myself talking, nor can I hear her at all !

I've learned some things lately about "actual db's" in a vehicle... and that most systems really don't model a lot louder than 120-125 db's > except for cabin gain, which might boost a lot of moderately upgraded systems (like mine) to 130-140. That said, I think I often listen to my music in the 130 db range. Loud, for sure, but not competition loud. So then on the SQ end of it, I just don't want clipping, or any crazy peaks or dips, or harshness. As for the sound stage.... ehhh... Not too worried about it. Even if I'm at a concert, what if I'm standing facing to the right. Its still not going to sound like its coming straight at me :) lol Oh, and of course, rattles suck, but everybody deals with them. To be quite honest, my GF and I go to a lot of concerts, and most of the time, I feel like my system is louder and cleaner. Has a lot to do with your seating position at the concert of course.

Those handheld dB meters are cheap.
You do it about 5 times in a few different vehicle and home and you find that numbers are all similar.

Turn off the sub and measure dB(A). (Or set it in dB(C) for the including the sub)

I usually use dB(A) as that is where all the vocals and music is at, and every car without a sub measures typically around 90 dB at a decent level... which is where many speakers are rated at in sensitivity (dB/w/m)...

Probably so, but I recall a lot of concerts that left my ears ringing for hours and wooley-headed for days.
