Ya that amp is only 300 watts rms-thats the continous power it puts out. 900 watts peak power. I would probably set the bass boost to 10, lpf to 50 hz, gain to about half way maybe 3/4 way.

You are a retard.
Set your bass boost to 0
Set your LPF to 100-115
Set your gain to roughly 3/4, give or take. Do this setting with a cd playing at a high but comfortable listening volume, the loudness you would have it if you were cruising down the highway to song you like pretty loud, turn it up until the subwoofer starts making a not so smooth noise, (slight distortion, then back it off a tad)

I agree, turn bass boost to 0 and never touch it again. Bass boost is a devil created by amp manufacuters. It serves no useful purpose. Turn it to 0 and i would reccommend setting your gain (input sensitivity as it's called on your amp), with a DMM. If you do not have a dmm then just set it by sound. Put on a cd on a normal listening volume that you usually listen to and adjust the gain until it distorts then back off some.
See bass boost amplifies the signal a lot, and in doing so causes a distorted signal to be sent to your subwoofer causing it to receive a clipped signal. If you look at a sine wave, like when setting with a o-scope, you ideally want a perfect sine wave. When you send a clipped signal to your subwoofer it will fry it very quickly and it is also not good for the amp either.
Also i honestly wouldn't be expecting a ton of output if your only running 300rms to a sub. Sure it's going to have some bump, but it's not going to be a lot unless you have a very efficient box built for it.
