Had my boom box upgraded almost 8 months ago and was never happy with the money spent ($1200 ) and the out come that I got. I have been using my iPod with volume set to max and made sure that the music was set for optimum in the iPod settings. I heard Mr Chinashop bull say just use a memory stick, so after some thought I did this and exported all my music to a folder on the computer then converted them to all MP3 format and WOW what a difference. Now I can hear my music at 130kph ( closed roads ) with out any problem. Thankyou China :)
