Alpine PDX-V9 settings

[-Raven-]

Hi guys, noob here lol!

I have an Alpine PDX-V9 amplifier to power my Alpine SPR-60C front splits, SPR-60 rear coaxials, and SWR-12D4 subwoofer.

For the subwoofer settings, I know I want to set the subsonic filter to 25hz-30hz and low pass filter to 80hz-100hz.

What I'm confused about is the filter settings for the channel 1/2, and channel 3/4.

Do I run the amp in full range with the filters set to off and let the speaker crossovers sort out the frequencies they play? (65hz-29khz from the specs)

Or use the high pass settings and set them to around 100hz?

If it were me //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I'd set the crossovers for 1/2 and 3/4 to around 65Hz since that's the bottom range of the speaker - I believe that amp has a 12dB/octave falloff. They switches should be set to HP (high-pass) - this will attenuate any low frequency signals (below 65Hz) so that they don't damage your speakers or muddy your sound.
