Im running 2 12 inch pioneer subs (Ts-w3002d4). With an 3000 watt hifonics zeus amp (zrx3000.1d). My question is what to tune the ssf and lpf to? I play mostly rap music.

What kind of box is it in? ported? sealed? If ported, what's it's tuned to?

For starters, u can set the lp to 80hz

Set the low pass filter anywhere from 60-120hz, it all depends on what sounds good to you and the ability of your front speaker to play mid-bass. Most people set it around 80hz, but there are many options. The sub sonic filter is designed to protect your subs from playing frequencies you can't even hear. If your subs are in a sealed box you probably don't even need it, if in a ported box a couple hz below your port tune or in the mid/low 20s should be fine.
