Can a PDX-5 take speaker level inputs?

I want to drive my new DLS R4's with the stock 6" base drivers using a 4 channel amp.
I have sort of narrowed down my choice of amps to either an Alpine PDX-5 or a Focal Solid 4.
I am leaning towards the Focal Solid 4, as I suspect the sound quality would be better.
However, I can get the PDX-5 for slightly less money.
The other advantage of the PDX-5 is that it will fit under the boot floor behind the seat, next to the bluetooth module; which is where the hifi amp would normally be. (I have the basic non-hifi setup).
I don't want to run any wires from the head unit, so I need a speaker level input amp. The focal will do it, but I have read conflicting stories about if the PDX will do it.
The main disadvantage of the Focal is that it cost more and I would need to install it in the side of the boot, where the first aid kit is.

It can take the OEM HU HiFi differential outputs, not the OEM HU non-HiFi, non-differential outputs (standard speaker level outputs).

Bringing an old post back from the dead. But does anyone know if the PDX-5 can take the speaker level output from the Logic 7 amp as inputs?

Read above please. Just because it is 6 years old does not mean that the answer changed...

The original post applies to the "OEM HU HiFi differential outputs, not the OEM HU non-HiFi, non-differential outputs" not the logic 7 output.

I am assuming from other threads the output of the logic 7 amp is 30-40V signal as speaker level out. Never seen an amp be able to take that (versus the 4-5V from the HU) but figured never hurt to ask.

Went ahead and purchased a clone of the lc6i and figure this way can at least get summation of the speaker levels inputs to output to the amp. Hopefully is sufficient to kill off some of the logic 7 processing.

So 4 channels of PDX-5 bridged into 2 for sws-8s and now a new IDQ12 sub in the rear. Should hopefully improve the bottom end at least.

Fixed.

Logic7 OEM amp output is speaker level output.

Other members read this post and could be confused by what you write. And then my inbox gets full, not yours.
