OK. So you want to power front speakers with a bridged 4 channel amp, and power the rear speakers with the HU, right? No sub- yet.
Yup, front drivers and tweeters off the amp and rear speakers off the HU
However, if you decide to add a sub later and use 1+2 for L/R front speakers(not bridged) and 3+4 bridged for sub, I would add another pair of RCAs because your HU probably has a dedicated sub out. So, I guess to save time and money(if you plan to add a sub), you could run the 4 channel RCA wires you mentioned earlier in the thread from the front and rear outputs on the HU and connect both rights to 1+2 and lefts to 3+4. Does that help? 
I have no intention of getting a sub later, so that really isn't an issue. However, my HU does have a dedicated sub out, so if I changed my mind later, I would use that to connect to a seperate sub amp not affecting my other connections in any way.
Right you are, but some crossovers allow each speaker to be amplified separately. Good luck!
This wouldn't apply if I am bridging the amp so that one channel is going to each set of speakers, right?
Thanks for the informative response
