Hi everybody. I just spoke with a car audio enthusiast and showed him the
gear I bought (not installed yet) and was told it wouldn't be a great idea
to use my amp to power the sub and the front coaxial speakers for some
reason.

My gear is:
MTX 404 4 channel amp (50W RMS x 4)
Kicker K65 coaxial speakers (to be installed in the front)
IDQ10 sub
Headunit: stock double-DIN Nissan Altima HU

I was planning on having the headunit power the rear speakers and run the
amp to power the K65s in the front and also the sub.

I'm not sure why but he seemed to think this wasn't a good idea (something
about not being able to control the bass or speaker levels well with my
HU).
He recommended I buy another 2 channel amp to power the front speakers and
use the 404 to power the rear speakers (which are the crappy stock ones)
and the sub. However I've kind of spent all I'm willing to spend at this
point.

Is there anything wrong with my initial idea (to power the front K65s and
the sub with the amp and power the rear stock speakers with the stock HU)?

Thanks to everyone,
Don

It will work fine that way.

sounds good....perhaps your sub will be under powered....but it will be a
good match with the fronts.....it'll be fine

Looks fine to me.

That problem can be circumvented by running the front channels of the
amplifer with the rear control on the HU, so that only the front output of
the HU runs the sub channels of the amplifier. That will allow you to use
the fader as the sub level control. Your enthusiast friend's idea isn't so
slick.

Your setup is fine. He just wants to sell you an amp.

Mark, does this mean I wouldn't have any output coming from the HU to the
stock rear speakers? If the rear output of the HU goes to the front
speakers and the front output of the HU goes to the sub, how could I power
the rear speakers?

Also, this sounds somewhat complicated to me. Would an installer from
Tweeter or Circuit City be able to do this without getting confused?

Thanks to everyone for their input,
Don

You run the rear output to the rear speakers as well. The line out
converter or speaker level input to the amplifier (whichever you decide to
use) is a high impedance load and won't draw much current from the head
unit, so it's ok.

Also, this sounds somewhat complicated to me. Would an installer from
Tweeter or Circuit City be able to do this without getting confused?

Yes. It's simple. You could ask them to run the main speakers out of the
front channel and the sub out of the rear, or vice versa. It doesn't matter
which. Just as long as you make it clear to them that you want to be able
to use the fader as a sub level control without attenuating the rear
speakers in the process. If they tell you that it can't be done, then
they're morons and you should probably go somewhere else. For what it's
worth, Tweeter hires better installers than CC. Although I know of a couple
that are chock full of fools.

Hope you like my drawing... is this how you mean:

l--------------------------l
l l
l HU front speaker out l X
l l
l HU rear speaker out l - Rear speakers
l l
l HU front amp out l - Rear channel of amp to sub
l l
l HU rear amp out l - Front channel of amp to front
speakers
l l
l--------------------------l


So using the fader on the HU will fade between sub&rear/ front
speakers right? so how can you adjust the sub level without
attenuating the rear speakers....
where have i gone wrong :-?

cheers

If your front and rear speakers are both on the rear output, it won't
attenuate them.
