hpf = high pass filter which allows ONLY the high frequencys to be heard and cuts all the bass out, this is good for when using it speakers so they dont distort

lpf = low pass filter which allows ONLY bass to be heard and is used only for use on subs.

bass boost would be used to boost the amount of bass at those frequencies. If u ahve a good sub, put it on +12db and around 40-60hz area. It will make the bass sound a lot punchier

bridging is where u put all the power of the amp into 4, 2, 3 or 1 channel. 4 channel amps can be usually bridged to 2 or 3 channels, and 2 channel amps can be bridged to 1 channel. It all dpeneds what u are using the amp for to what settings u set on the amp.

they are to get the sound from ur head unit to ur amp. If u only have one set of RCA's from the head unit, u will need to buy some splitters that will split each output into two so u can plug it into the amp properly.

the output red and white is to daisy chain sevral amps ie out from headunit into channel A (or with splitters into channels a & B) and the for a second amp from output red and white into channel A on amp 2 and so on and so on.....
