I see this all the time with my friends.
First off, they get the cheapest crappiest sub the can find that get's loud. Then they fit as many of them in their car as possible.
They're always trying to out-do each other. You can't even hear the words, just BOOM BOOM BOOM.
You can tell a possible candidate for future hearing loss. I've seen them on this forum.
They ask questions like this:
How loud do you think it will be outside the car?
How many blocks away will I be heard?
Which gets louder, 3 15's or 2 18's?
Can you guys help, How can I make my system louder outside of my car?
I have enough space for 2 15's, and I want to out-do my friend, what subs do you think I'll need for it to get as loud as possible?
That type of stuff is idiotic to me.
They're wanting a loud system just so they'll be heard blocks away, but in 15 years, the people that heard them coming will still be hearing just fine, but the "show off" that spent all his money 15 years ago on his 47 15" 2000watt subs is now spending all his money on hearing aids.
I think at one time or another we've almost all been there.
With some people it's just a stage you go through in the beginning, that hopefully you grow out of quick enough to keep most of your hearing. But with others, they just have to learn the hard way and lose their hearing permanently.
LOL!
And they wonder why their "dream system" that was SO LOUD to them a year ago isn't as loud to them anymore. YOUR LOSING YOUR HEARING!!!!!
I'm glad I've quickly grown out of that stage, and can still hear just fine.
I am proud to say I'm just an SQ guy now.
Because there is more to "music" than 4 15" 1500watt subs & 4 2000 watt amps blasting loud drums and basslines, and then just having some 6-3/4 speakers ran off your HU power.
I now like everything balanced and accurately reproduced. Not driving daily with 150db drums, with only 63db mids and highs.
Hearing is precious, and I plan on keeping mine.
