Re: Alpine CDA-9805 CD deck.
Can this deck be set up to provide control over the High pass/Low pass
crossovers for
the external amp(s)  and Sub amp?
In the owners manual Alpine covers using programable settings, it shows a
BASS center frequency adjustment in the manual for 60, 80, 100, and 200 Hz
(plus Bass width, level and type settings) and a TREBLE center frequency
adjustment for 10, 12.5, 15 and 17.5 kHz. Are these the same as actually
having a external crossover do the same thing ie: high/low pass at specific
frequency?

There is a setting to turn off the internal deck amp as well when you use
external amps.

Sorry to be obtuse, I have been all over the FAQ's, Crutchfield, popular
sites etc. etc. but the manual is kind of sketchy.

Thanks all.
Lots of good reading on this group.
