RF amp settings/tweaks...any ideas?
 

finally installed my system - am using RF 500bd amp, pushing 2 JL 12W3V2 - now as far as the gain goes (i've got that figured out!) there's a built in crossover setting, says it ranges from 50 - 250 Hz. what does this setting do? i've fiddled with and haven't really noticed any difference either way, and don't know what i should/shouldn't be listening for.

as well as on my deck JVC KD-SH1000, there's a setting for the sub freq where i guess it excludes certain frequencies...same as above. no idea :|

thanks for anyone that knows what i'm talking about.

is the freq. setting a dial or just a switch?
as for the head unit, iv tried the different crossover settings on mine and none of them seem to make any diff in sound so i just have them set to off.

there's a dial for the crossover freq setting, then there's also a switch for LP - low pass... ??

When that switch is set to Low Pass the knob will control how high the amp plays, i.e. it allows the lows through but blocks the highs.

Most people set this in the 60-100 range for subs.
