ill jump in on this one... each pre-out is a pair of rca connections.
2 of those pairs are for your "interior speakers", each single rca plug is "1 channel"(1 ch)... so 4 total individual rca plugs mean 4 channels(4 ch)... right front, right rear, left front, left rear... good so far? those rcas plug into a 4ch amp and then you wire the interior speakers to that amp.

now the 3rd pair of RCAs are for your subwoofers. they have a specific signal just for for the lower "tones" of the bass. they are right and left(stereo).

the 50wx4 on the headunit is the power output the headunit ALONE would put out to the interior speakers if NOT using the pre-outs. if you wanna run a 4ch amp you can, but have to run speaker wires through the whole car. in a simple system, the 50w will do for most interior speakers. Higher end ones work better with more watts.

i would recommend Pioneer head units till the day i die, that is ALL i run. I just installed their one bluetooth compatible head units. i love it.
