I love to crank my stereo but i'm courteous about it always turn it down when at stop signs/lights at the windows are down & never play loud in residential areas. I've got enough forms of deadending in my car I don't get that annoying ghetto rattle.
While i love to bump along sound quality is where it's at
.. oh and yes i've got way more in my car stereo than my car is worth and the things only 4 years old just in equipment. If we were to put a monetary value on the time i've spent well then I would probably get depressed LOL
