Speaking for myself, I came to this site because I subscribed to Car Audio decades ago, and searched for the name specifically.
I came here trying to get an idea on a problem I was having. My system is set up, and not changing. i don't compete. So, there is only so much to discuss.
I offer help where I can, but many of the questions and posts outside of the lounge are product-specific, which alone limits the number of responses you'll see. My knowledge is more the system how/why/what/where, as opposed to "Where in the sub-menu on my Temu head unit do I set my crossover?" or "Should I buy the XYZ amp or the QMR amp?"
Are they rocking with conversation about car systems, or rocking because they have a high volume of the same asswer to a question (like a Reddit post getting 1,500 of the same response, or even incorrect ones after a correct one has already been offered)?
If it helps, I'd have no problem posting something, ANYTHING, in as many non-lounge threads as possible, but I tend to avoid those threads where I'd just give a ditto or an "I'm not sure about your Temu, but it's in this place on my Pioneer" (not much help).
