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.
The only reason you would want to use 2 pairs of RCA plugs instead of 2 Y adapters would be to retain the fader control on the HU, which would be pointless in this situation. IIRC a 4 channel amp is 1+2 and 3+4, so run a single pair of RCAs to the amp, use 1 Y on the right and connect to 1+2, use the other Y on the left and connect to 3+4.
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?

Right you are, but some crossovers allow each speaker to be amplified separately. Good luck!
