Amp Install = Airbag LIGHT!! HELP TO RESET!!

[ramacts]

Somebody please help.

I just installed a amp into my TL and after having the battery disconnected for a couple of hours and poof I have the airbag light on.

I'm right out of warranty and the dealer wants $115 to just figureout the problem.
There has got to be an easy way to reset this light.

Somebody please help.
Amp install consisted of :
-Power wire thru firewall and into trunk. Ground to exsisting one in trunk.
-Remote wire to>accessory wire under dash.
-And the RCA cables to source (Sub Input)

Checked all panels, no wires crushed.
Can't figure it out.
Please HELP SOMEBODY.
Thanks ahead of time.
