Can I have some hook up advice for a 4 channel system

[jetmech727 10+ year member]

I have an Alpine CDM-7861 HU, PG Ryval 4 channel amp, and a Rockford Fosgate Mono Sub amp. What do you guys think is the best way to hook this system up? The Alpine has 2 pre outs, one for the front and one for the rear and speaker level outputs as well. The rear can be assigned to a sub out. The Phoenix Gold has an option to have the front amp input supply signal to both channels of the amp.

1: Should I run the rear output as a sub out to the Fosgate Sub amp, then run the front output to the PG amp and use the amps option to have the front supply the whole amp but have no fade ability?

2: Run the rear pre out as a sub out, convert the HU rear speaker out to line level and connect that to the PG Channel B, then connect the front pre out to Channel A of the PG amp and have fade ability?

3: Run the HU rear speaker wire out and connect as above in example 2, but use the rear high level speaker output to the amp and not convert it to line level.

4: Do not use the rear speaker out as a sub out and connect the 2 pre outs to channel A and B of the PG, then use the PG aux out and run that over to the Fosgate Sub amp?

I hope I've not caused to much confusion.

Thanks

If the 4 channel can accept speaker level input, then you might as well go for option #3.

Once you get the front to rear fade dialed in the way you like it, you won't need to make anymore adjustments. But it's nice to have. I have mine split at on the 4 channel amp, because I don't have enough outputs. I don't miss it. (I use the rear as a sub out)

I would not add an extra speaker level converter if the amp already has one built in.
