and it that don’t work maybe the next step is an ear exam! you might be deaf. after years of getting seats next to speakers at rock concerts, i am. i have to turn the volume up to -4 or -5 bars on my tr1 (if i go higher it hurts) and i am using some REALLY CHEESY apple ipod headphones. but d**n, it still sounds so good! i also got a copy of music match’s dfx 6.4 which does some mp3 processing that’s pretty cool, and increases the volume of mp3 playback, amoung other tweaks. good luck, and remember to never wear headphones when driving under the influence of drug of choice and while also watching a dvd on your dash-mounted tr1.
