good stated...it was challenge and scienceFor me it was and my group of friends (which held a bunch of state records at the time) it was about the science of it. Most of us didn't even listen to music in our spl vehicles. I was told I couldn't hit 150 out of the just the trunk of my maxima and I took it as a challenge, then I was hooked on pushing the envelope. None of us EVER showed off flexing panels. In fact we would have been embarrassed if our panels were moving more than a sheet in the wind. That would have been proof of inadequacies.
