the protection light will not come on if you have a short in the 12v+ somewhere (remote-turn-on or otherwise), but will come on if the speaker wire is shorted out. i would check there first.

also, hook up the power (12v+), ground (12v-), and remote turn on- and make sure the amp comes on first before you plug in your RCA connection(s) from the headunit. if the amp doesnt come on, you probably have a falty ground (the eclipses have lots of plastic screw holes that dont actually touch the chassis). if it does come on, you are set, and you can then plug in the RCAs. explination: if the amps ground isnt connected properly, it will reference its ground through the RCA shield, back through the headunit, and to ground. this is a lot of current to be sending through the headunit, and will eventually cause damage.
