Front and Rear HU Output (joined to 2 channels or separate as 4 [not sure if you can join RCAs, i think you can but im unaware of the quality consequences. However I don't think it should change too much]) -> Amp -> Front outgoing and separate woofer wiring

If you're worried about your rears being completely disconnected, which i wouldnt, then you can probably find a way to split the rear incoming:

Rear HU Output -> Split between Amp AND rear outgoing -> Front outgoing and woofers

Again i'm not too sure if this would have any quality consequences. But even with this, your rears will still be a lot quieter than your fronts, so there's probably not much point in doing this.

So to keep your rear PDC without amping your rears, then these 2 solutions should work, but you'll get the gongs at the front obviously

OP
If you were to use MS-8, the above method is valid and MS-8 will create cleans signals for amp.
Considering your amp, there will be -ve consequences of this method on your sound output, and as mentioned do it on your own risk.
