Does PR code 8RM mean I have a 4-channel amp with full-range signal?

[Pipzap]

Hi all,


I have a 2017 Seat Leon 5F with PR code 8RM (8 speakers, passive).


Does this mean my system is using a 4-channel amp (built into the head unit) with full-range signal going to each speaker pair (front/rear)?


I'm planning to install an aftermarket subwoofer and want to confirm if it's safe to tap into the rear speaker wires without missing low frequencies.


Thanks in advance!

8RM is 6 channels
front left high
Front right high
Front left low
Front right low
Rear left high and low
Rear right high and low

9VD is also 6 channels (seat sound)
Front left high and low
Front right high and low
Rear left high and low
Rear right high and low
Subwoofer
Dash speaker

Install Seat Sound and benefit from an overall improvement rather than just bass

Thank you for the reply. Does that mean I Can tap into the rear speakers for high level signal that is full range?

i Will start With the sub i have already, and maybe upgrade further in the future.

Thank you very much. Now I just need to find a diagram for the radio harness of this type, to know which wires are the rear speakers. Would you happen to have that at hand aswell?
