[QUOTE="snoopdan, post: 2461555, member: 564991"] Great to see you're enjoying those subs, they were one of the more fun one's ive had the pleasure of testing. If the LED isnt lighting up (and im sure you've tried to independantly power it somehow, or at least made sure the power wires werent in reverse) then the next thing id do is grab a multimeter with a diode check (most multimeters have this) and do a value check on the sub with the functioning LED, and find out what the value reads (and it will only read in one direction of the current, so make sure you have your leads right, if not just reverse and see if you get a value). Then as soon as you get a readable value from the good one, see if you can reproduce it on the sub that wont light. If you get an open value and or nothing read, the diode is probably shot .... usually this happens due to overvoltage....not suggesting how this happened or why, just that this is the probable reason. and the coolest thing is, if you ever blow them, you can recone it yourself in like 5 min with a recone kit from Massive....requires no glue or special tools.
