Finalizing my system this weekend and request help on crossover settings. My HU has built in HP/LP; my Polk speakers have both HP/LP filters; and my amp (Profile 4400) also has HP/LP. With all three having these filters, do I need to set them all and what settings? Sorry, I don't have a good understanding of these filters.
My updated setup for my Sport Trac is:
Polk DB570s in all 4 doors
Audiobahn A2002T amp (bridged 200w/RMS for sub)
RF 3408 8" sub
