If the speaker is working then the "power on" LED has a broken wire/bad connection or the LED has burned out. LED's don't burn out often so I would think it is a internal factory wiring issue. If they're still under warranty, have EV fix it.
1. (STEADY ON) - RUN THE POWER FROM THE AMP TO THE POSITIVE LED TERMINAL THE NEGATIVE CAN BE RAN FROM THE NEGATIVE SPEAKER TERMINAL.
2. (INTERMITTENT; COMES ONE EVERY TIME THE BASS HITS) - RUN THE POSITIVE AND NEGATIVE WIRES FROM THE + AND - TERMINALS TO THE POSITIVE AND NEGATIVE TERMINALS OF THE LED LIGHTS.
Bought a S10.3 in jan/2010, LED died a month later. I've repaired it by myself. After inspecting circuit, I've found that their design puts almost 14V of reverse bias upon that poor blue LED. These components are not usually expected to sustain more than 5V of reverse polarization. So, in my opinion, there is a design flaw. To make a long lasting repair, you just need to insert a general purpose diode in series with the LED, such as an inexpensive 1N4148 ($0.05). And, of course, any readily available 3V, 5mm, through-hole round blue LED (I think crystal clear should be better).

only on fixya would we get a complaint that speakers that are supposed to make sound work great but some lights on them dont work....
ugh.. ok with most of the spealers that have l.e.d.s typically have a seperate connection for the lights. The red wire goes to a switched 12 volt power source, the black goes to chassis ground... if they have power and ground but dont light up then they are junk...
