I'm a car stereo newbe. I'm very good with a wrench, so I purchased
from Ebay & installed it myself. Alpine CDA-9827 HU, Alpine F450 amp,
Blaupunkt Seperates F & R, Rockford 8" sub. The install went fine,
everything powers up and functions properly.

My question..........
the amp has Off/HP/LP & crossover adjustments from 50-400Hz for
channels 1/4, it also has Subsonic Filter Off-15Hz-30Hz; Crossover
50-200Hz; & Bass Eq 0-+12db for the sub-channel 5

the HU offers "Bass Center Frequency" settings from 60-80-100-200Hz
and "Treble Center Frequency" settings from 10.0-12.5-15.0-17.5kHz

The speakers have passive crossovers at 3.5kHz w/12db slope

I've never set up anything like this before! Where do I begin???

THANKS IN ADVANCE to the EXPERTS for ALL YOUR HELP!!!!!!!
