Very simple process.
Take off the case.
On the top left hand side of the amp, near the RCA's you will see a small white spring loaded button, you want this to be UNdepressed.
Now, in the bottom left quadrant of the amp... locate resistor Q240... make sure it is Q240 . Use a soldering iron, and a ulility knife to remove this... kindof flick it off.
Done. Now your amp is modded, it'll put out roughly 1800rms @1ohm.
