LPF- i think maybe low pass filter
HPF- high pass filter

i don't know just a guess, and also call or check out your head units's company website.

Good luck

Just slap the b*tch on the back of the head and tell her to get to it!!

Seriously do a google search for the head type and model number and you WILL find a manual online!!
