[QUOTE="thch, post: 3276973, member: 562032"] pretty much. I'd play some test tones around 20-30hz and just drop the SSF until I was comfortable with the excursion. (bass boost and excessive gains can effectively lower the SSF) gain = level setting. There are many guides to this. in short - it adjust the amount of amplification. because not all HU's put out the same signal strength, it is made to accomodate most/all of them. unfortunantly, this means 100% turn may not be 100% volume! In many cases full gain settings would give too much gain, and the amplifier would be forced to distort. This can cause equipment failure in severe cases, though mild clipping is not normally concerning. If you have friends with car stereos, you might have seen the "its soooo loud at volume setting 5/30." This is because the gain is high enough to give near full power at such a low level input signal. as they turn the volume up, the sound gets more and more distorted without getting much louder, usually reaching a "this sounds unsafe" level well before reaching 30/30 on the HU! lowpass is used to remove vocals from the subs. highpass filters remove bass from the other speakers.
