Active subwoofer on factory head unit HELP

[Skeeuk]

Hi, I have spent all day splicing into wires on back of head unit and nothing is working.

I'm splicing front left + - and front right + - going into line output converter. I can't get any audio out? Anything I'm doing wrong...

I noticed front right and left have 2 wires in each plug but rear left right only has the single wire.

I have even tried splicing into rear speakers still no sound.

Any help much appreciated I've done the same to my other car no issues.

You need a converter to take one of your speaker level outputs to line level, if you are already doing that, then I dunno

That's what I've done I've attached the speaker spliced wires to the line converter but no sound. There's zero guides online how to do this

Possibly. I might order another and have another go
