SQ - well a driver sounds
SPL - sound pressure level, the amount of sound in the car in decibels(how loud it is)
For rap prob in the mid 30's like 35. i prefer a 30 htz tune personaly.

I assume the ss box is ported and u are talking about the infrasonic filter(subsonic filter).
When a sub drops to far below tuning the port(vent) is unable to control the woofers excursion. Essentially the woofer goes free air. this can damage a subwoofer. imagine putting 1000 watts into a ti without a box. not pretty. the infrasonic filter is like a crossover. U set it where u want the sub to "roll off".
ex. if the box is tuned to 30 htz then one should probaly set the infrasonic filter to around 23-26 hrtz to protect the sub.
It is simple to do. some amps are preset.But the ed nine.1 is a nice amp and might have a nob that u can use to set the frequency that the infrasonic filter will began its roll off.

Built in Subsonic Filter. The eD NINe.1 also features a on board subsonic filter. The amplifier is versatile enough to allow you to use whatever boxes you use necessary. It works with you, around your equipment and requirements.

32 htz would be nice.
SPL - level of noise.
