FREQ. stands for frequecy. Your amp has a built in crossover, you should have it set to LOW PASS. The FREQ. knob should be set to about 80hz. or lower.

SENS. stants for input sensitivity, set this to match the preout voltage of your head unit. It's basically like a gain or volume for the amp.

AUX is only used when you want to hook up a 2nd(auxillary) amp, but your head unit only has one set of preouts. Than you could use your amps auxillary outs and crossover with the 2nd amp. My friend calls it "piggybacking".

How do I know what the preout voltage is I have an Eclipse 5540 head unit.

It is probably 2 volts, although some eclipse head units have 4 or even 8 volt pre outs. Check your owners manual.
