How can you handle it?

Hello together! I’m totally confused, I have to confess. I talked to a friend earlier, who also runs a small car-hiFi business. So, since I’ve been here for a few years (formerly Nick), I think, I’ve accumulated a lot of know-how in my car by reading a lot of other people’s experiences and lots of rehearsal hearings. But how do you deal with it when you meet someone who thinks you have the plan and pretty much everything you need to know? r tells me about his awesome Emphaser Amp. I didn’t say anything about it…. Then he asks me about my components, I tell him, the Twister and before the QT15 on the PA2802 and that I usually hear HipHop… He like this: Then show me your band pass. I tell him I didn’t have any, but I always had the QT BR. Then I just didn’t get any understanding. No BR would still press properly at 20HZ. I’ll tell him if you’re tuning the band pass so deep ass, he’s got such a rough peak that there’s garnix in the upper bass and I can’t use the part in a tonal view. He means na KLAR, nen JL in the band pass goes still like sow at 20HZ and is still right in the upper bass, besides that JLs are famous as fast and fart rock the play. Okay…. Also I just left it like that and put myself as the Noob, no bug on the ground then he asks why 15 at all”. I tell him because I like to have a little bit more bass and the QT is so fast, that it can be late for me if it’s 15″ or 12″. Especially with HipHop… Again only unbelieving looks harvested… Well, I also accepted it. Then someone else comes and tells me partly already aggressively and 100% convinced that I would be completely stupid because I had a sub in the car. He would have a buddy who would have just 4 20s basses on the rear shelf and they would still press like pig at 18HZ (NO I HAVE NOT HEARED!!!). When I then meant how this should be done physically, he was partty… What do you do in such situations?? Would I really be interested in… THANK YOU!
