Can someone tell me what side is the - neg. contact of the speaker in this pic. this is a picture of the right speaker in my dummy psp. i was thinking of using the left speaker - neg. point for the left LED, and the right speaker - neg. point for the right LED, to cut down on the amount of wire behind the LCD screen.  i just need to know which is - neg. on the right speaker. is it the left or right contact? thx guys.
