Sub unhooked for 2 weeks, re-hooked and wont work??

[talisin]

I have:

- a 15" JL

•15" Single 4 Ohm W0v3 Series Subwoofer

•Power Handling: ◦Peak: 1000 watts

◦RMS: 500 watts

- Pioneer GM-D510M 1000 Watt Mono Amplifier

Everything worked great, installed myself a year ago or so. i went on vacation and unhooked Sub from amp and removed sub from my truck. went away for 2 weeks came back, plugged my +/- back in and now nothing. Idk what could have happened, i didnt adjust anything or unhook anything else. Amp is still turning on and working fine, just nothing coming from the Sub. I rechecked all wires, replaced my speaker wires, repolished and hooked up my ground. Still nothing. I have no idea what could have happened in that 2 week span. please help.

did u use a dmm to see if amp is outpiting?

my 1st instinct is to tell you to check the deck settings and make sure "sub output" is on
