When I bought my system, my boss's partner who ran a different part of the company said, "Dude, you're an idiot! with the same money, you could've gotten two-times better quality from JL!"
He then showed his great intelligence when a coworker went to show me his system which consisted of a Sony Amp and XPLODEZZZZ. He knew it wasn't anything good, but my boss's partner said, "See?! Those are subs! Put your head in the cab! Your eyes feel like they're gunna pop out of your head!"
I said, "I'd rather not. I like my hearing."
After I installed my modest system, I went back to work and cranked it and his mouth kinda just dropped.
On that note, I need to build a bigger box... and port it. This .7CuFt before displacement sealed just isn't working too well.
