Hi,
I have a 2019 SEAT Ibiza and I'm trying to install an amplifier and subwoofer in the trunk.
I've already run the power cable from the battery to the trunk. Since I didn't want to cut into the car's original wiring, I bought a plug-and-play adapter with RCA outputs and a remote wire that connects directly between the factory head unit (located in the glovebox) and the original wiring harness. I also ran the RCA and remote cables to the trunk.
For the ground connection, I used a bolt located underneath the rear seats.
The amplifier and subwoofer were previously installed in my Mk1 Leon and were working perfectly. The wiring kit is from Focal and is the same one I used before without any issues.
Everything seemed fine during the installation, but I'm having a problem: the subwoofer doesn't produce any sound at all. The factory speakers are working normally, and I have both power and remote signal at the adapter and at the amplifier.
If I disable the LPF (Low Pass Filter), I can hear music coming from the subwoofer, but it's extremely quiet. As soon as I enable the LPF, there is no sound at all.
I've also connected the subwoofer in bridged mode on the amplifier.
What could I be doing wrong? Is there something I'm missing or overlooking?

Any help would be greatly appreciated.
