stereo/head unit to an amp
I have a head unit with only 1 rca output and it is attaching to a 1600 watt 4channel amp. The stereo says it is a 4 channel but only has 1 rca output. Will the amp only output 2 channels and therefore only 800amps?

By stereo saying 4 channel, do you mean it says 50x4 watts? If so, that is just the max power if you run speakers of the head unit. It only has 2 pre-outs for an amp, you can buy splitters to give you extra pre outs, but you will lose quality.
I don't think your amp is actually 1600 watts... that is probably the "max" power. Check the rms/channel. This will tell you how much power per channel you are able to use. So in theory, if you only use 2 channels (lets say for your front speakers) then yes, you will only use half the power of the amp. This isn't necessarily a bad thing.. you're just wasting power.
What exactly are you trying to setup here?

I have cd/mp3 head unit and i am running the rca output to a 4 channel 1600 watt max(output power rating@4 ohms is 35wx4), from there i have a 800 watt sub with a built in amp and 2 rear speakers(200 watt/rms) and 2 door speakers (80 watt rms)

hmmm... weird.
How are you getting signal to the self amped sub?
Don't pay attention to the max power of the amp. You have very mis matched speakers for the amp you have. You should aim for an rms rating per channel @ the same ohm level as your speakers need. So an ideal amp for your rear speakers would give 200rms and an ideal amp for your fronts would give around 80 watts.
Do a bit more research on the basics of car audio stuff and you'll get a better understand of how all the main components shoudl be matched/chosen.

Only two ways I can think of that this is being accomplished (logically, anyways)... A splitter on the one set of RCA's into the 4 ch and using the 4 ch's throughpass output to get signal to the sub. The other way is using a couple line out converters right off of the deck's output, and the throughpass on the 4ch to get signal to the sub. The first option is only using 2 channels worth of signal, the latter uses 4.

^^assuming the amp has through pass??? The easiest and maybe best solution is to get a graphic eq with sub out, and that will act as a splitter with no loss to signal quality, plus you get the benefit of the eq, sub control, x overs..etc...like this one:

OP, what are you really asking? I mean, what is the end-game? Your question doesn't explain what you are trying to accomplish... Are you simply asking out of curiousity or is there a problem you are trying to solve?
