I just purchased this headunit earlier this week.

Anyways, I started having problems with it. Sometimes, when I start up the car, my normal (non-sub) preamp output deactivates itself, so I only have the sub playing.

The problem seems to persist until I re-download my setup info from my CD that I made from the i-personnalize website. Would anyone have any idea what's happening and how I can correct this ?

 

Problem solved........
I replaced the headunit.....
