wiring rear door and rear roof speakers

[bluebear15]

i'm looking at setting up a new system in my tahoe. heres what will be going in:

Alpine IDA-X303 (Head Unit)
Alpine SPS-600C (front door speakers, component)
Alpine SPS-600 (rear door speakers, coaxial)
Alpine SPS-609 (rear roof speakers, 6x9)
Rockford Fosgate R300-4 (speaker amp)

also going in but i already own:
2 Infinity 12" subs
Rockford Fosgate P325.1 (mono amp)

since the HU has 3 rca sets (one for the sub amp and 2 for the speaker amp) and the speaker amp only has 2 rca sets, i'm looking to wire together the rear door speakers with the rear roof speakers.

my question is whats the best way to go about wiring them together?

Parallel, series will net the wrong ohmage.

 

[bluebear15]

is there a "best" area to wire them in parallel?

 

[Mike]

I would send them out as two sets that met at the amp.

 

[bluebear15]

ah so wire them directly to the amp is what your saying?

 

[Mike]

That is correct
