S120PII Subwoofer didnt use the amp for a long time and now there is no power.

It could be a power fault (polarity is crossed), thermal fault (amplifier is too hot), subwoofer fault (subwoofer is blow or impedance is too low (ohms)), or either the amp has been ran too hard, meaning you played it till it went into themal, turned it off, and turned it back on to reset it, didnt allow it the time it needed to cool off, and continued to play it. If you did that, its hard faulted, and you need to repair or replace it.

its for the led light red and green red means in standby position and green means its on

try pluging in a diff, speaker to the amp see if u get sound.try powering the sub with a home radio just to see if u get sound at all if ur getting sound from the sub then its the amp but u could of damaged it when the amp over heated

you may want to check your grounds, your remote and of course the battery terminal. it seems obvious, but many times small things can cause big problems.(i.e. try cleaning the battery terminals)

Same thing happened with me. Did you ever find a solution?

get a nice monster subwoofer cable and a Subwoofer PowerCenter™ SW 200 with Clean Power™ Stage 1 get it from like amazon and you'll definately see a difference and also put the sub in like a corner

did any 1 get a solution for this problem???

probably you had cause the wire to ground out the set.causing the short out to damage the power supply take your set to a tech to check it.and possibly to repair.good luck.

it sounds like the posotie side of your amp is bad or the soder point is broken

Sounds like a fuse issue in the power from the amp - the remote circuit could be and probably is completely independent. haven't been able to find confirmation on this, but if you are confident to take the cover off then check (probably)around the area where the power terminals are there may be some fuses. Hope this helps, ask again if not :)
