Nac -Clarion 9170 wiring

Do you have one(9170 or 9270).  I was trying to figure out what of the RCA sets was F, R
and controller.  I think I've go it figured out, but seems the F and R ones are so hot
they overdrive any AMP I put them on - almost like they are line out level and I should
wire directly to speakers - that is RCA cable with one end cut off using those leads to
the speaker.  Would be nice if Clarion posted the obsolete unit manuals, but these are
no where to be found.

One of the sets of RCA's seems to do the trick when chaneeled through the digital
controller box - mixes single signal to F, R and Sub as well aproviding a bunch of
effects.  There are no direct speaker outs as far as I can tell - this unit channels all
output through RCA connectors  the three sets  I assume one for front, one for rear and
one for digital signal control.

I seem to be getting a lot of clipping with the unit, but probably with inadequate
powere feeds - testing system layout on a bench prior to installing in vehicle.

If you by chance have any manuals or info on this or similar model, it would be helpful.
I am also trying to figure out what all the different button controls do.  So far I am
able to make the unit run the 20 disk CD changer, tape and radio, and rand three
separate amps - front rear, and subwoof via digital control unit.  Would be nice to be
able to power second set of front and rear's off the other outputs.  I still don't know
if the thing fades properly front and rear - too much flakyness with the controls and
test amps/wiring to tell for sure.

Not pumping any more money into the system - on the contrary, I had the system and want
to use it since it would be perfect for a '91 200Q I'm doing.

 hey ben there's really no magic to it, the 3 sets of rca's are in fact, front, rear and
non-fading sub level preouts. this way the subwoofer level is not effected by front /
rear fading. typically the radio has a seperate level control built in fot that preout /
sub channel. very nice feature. 99 out of 100 times all aftermarket radio co's use the
same color coding scheme. if you go to the local shop and flip thru a manual for a
kenwood, alpine, whatever i bet you'll get there. i installed these for a while and they
had great features, 2 year warranty but never proved to be very reliable so i wouldn't
sink any/much $ into it.

as for the wired outputs, usually it's yellow - constant:12v, red: switched 12v, blue:
amp turn on [12v output signal], black: ground. many newer / higher end radios have
other outputs for powered antenna lead [usually purple], illumination [orange maybe?],
and to remotely power on your coffee maker. the speaker leads are normally grey / white
[front left/right] and purple / green [rear left/right]. i forget which is which but
that's easy enough to test for [hook the radio up to the battery , rca your ipod into
it, and start testing things and measuring outputs].

the changer cable will be proprietary but with enough time and patience you can make one
if need be with digikey parts [wont be pretty, will work].

hope that helps. whatever you do.. don't cross the streams!
