[QUOTE="Prowler573, post: 1464812, member: 561023"] [IMG]//content.invisioncic.com/y282845/emoticons/bigwave.gif.16324171cad2db62cf4f16568b038478.gif[/IMG] Welcome to the forum, Tim. You'll want the crossovers in the 300/4 set on HP. This stands for [B]H[/B]igh [B]P[/B]*** - ergo it allows all the frequencies at or higher than your chosen setting to pass through the filter while stopping everything below your setting from getting through to the speakers. Try starting at about 60Hz and adjust it up or down from there until you get it to a point that your ears tell you, "That's it!" You wouldn't want to leave the amp's crossovers turned off because the component sets came with their passive crossover units. All those do is route all the highest frequencies to the tweeter while everything lower than what gets sent to the tweeter will be routed to the midwoofer. You'll still want to utilize the HP crossover in the amp to keep the lowest subbass that the components aren't suited to handle out of them. Having the LP crossover (or [B]L[/B]ow [B]P[/B]***) in use for your sub is the correct setting. Try starting about 75Hz and again, move it up or down until your ears tell you you've gotten it where it needs to be. An LP crossover is exactly what it sounds like, the exact opposite of a HP crossover. Good luck getting it sorted out, friend.
