I wouldn't have a problem with a lowpass filter already aplied. I'm just missing some deep, low end bass which I want to add with an amplifier and subwoofer.

The eMost solution looks interesting but is a bit pricey for my taste. It's just a PreAmp so you'll also need an amplifier with the necessary harness to your speakers, and probably an extra amplifier for the subwoofer.

Pins 1, 10 and 2 of connector 2 in de diagram below connects to the subwoofer amplifier of the advanced sounds system. It looks like an audio connection. Perhaps we can connect our own amplifier to those pins?

I just can't seem to find the right harness or breakout-box for this connector, so I can rewire those pins and distribute it to the trunk.

I see what you mean. Mine has the standard sound system too unfortunately. My dealer told me they won't upgrade the soundsystems anymore. Searching now for a suitable solution without compromising trunkspace.

That is odd. I'm finding my way through the workshop manual and this states that it's in the trunk. Did you manage to make it work? Also I've got the A200 Hatchback. So it's possible the units can be in different places per model...

Hi Adrian99, could you be so kind to share the video with us? I also want to upgrade my audio and i'm searching for the head unit.
