I just hooked up a Pioner 5900 HU. Before the install i already had a sub and amp hooked up to the stock headunit. At first my sub was working with the new headunit, but when i opened my hatch..the sub cut out and now it won't turn on.

Anyone know what could be causing this?

 

is she blown?

 

i don't think so, because the bass was barely even up...Also I forgot to mention this happened twice, cause I had to take out the headunit to plug in the i-pod cable so again it turned on, then off when i went to open the hatch...

 

something sounds loose then. double check all of your connections.

 

yea..i did check em again the 2nd time but i'll check it again later today, thks.
