It's been a while since I was in the industry, but I can assure you that most of the shit that you said is wrong.
Sony head units were never superior to Alpine, and I doubt that they are today.
MB Quart tweeters are very harsh and tinny sounding. Not to mention that you can't compare speakers from radio manufacturers with speakers from speaker manufacturers. And anyway, what about Polk Audio?
JL subs are good, but there's nothing wrong with kicker.
I've heard that Punch amps are shite now. I still like my Punch 100 though.
"Be sure to get a passive crossover or equalizer." - Yeah, those are not at all the same. Most EQs have a built-in electronic crossover, but not all. And, passive crossovers rob punch and power from your subs.
Building your own box is fine, if you can calculate the internal space and know about wave cancellation and port tuning. Oh, and if you build a sub box out of plywood, you should be shot. Plywood is much too light and lacks the density required to eliminate resonance. Use MDF or particle board instead. Can you tell me what exactly "speaker flex interference" is?
You're pretty much right about the sizes of woofers, but you don't need 15s to get deep bass. You can get a set of 12s to drop just as low and move nearly as much air in the right box. I built a bandpass box with 4 12s once that hit +10 dB at 13Hz, (141 dB overall, with a mean peak at 13 Hz) so that kind of blows your theory about 15s hitting lower.
I guess I remember more about this shit than I thought. I just don't know the latest products.
