I know exactly what you're saying 78nova. I get the same thing around here with JL Audio, Rockford. People ride around bumping their systems, bragging constantly that JL is the king of subs, showing off their installs (which is usually just a box and amp thrown in the trunk).
Car Audio is competitive just like anything else, and the bragging can get just down right annoying. Most of these people will never compete on a higher level to test their system, they'll just continue to run around and brag that whatever they have is the best.
Same with cars, computers, TV's, sports, etc...
The problem with these people is that they seem to convince others and drive them to buy this brand and they won't be convinced even if they hear something better. It's NEVER better. Then you'll hear, oh your system is good, but mine is better ... they'll crank it up, you'll raise an eyebrow and alot of times people around agree with them mainly because they hype their stuff up so much.
The same people from High School are still bumping JL's with the attitude they had back then; and it's been 8 years so not always do things change. This summer will end their brand loyalty. Time to open up eyes and minds :up2someth
