Hi everyone, hope i'm not bothering anyone with my questions, and if the topic is in the wrong section the admins will be kind and move it to the correct one. I have recently bought a MY15 Octavia III Combi with the Canton Audio System and like most of Canton owners i'm pretty dissapointed with the stock bass from the Sub (my other Octavia, a 2005 with stock sound system is better than this 😅 ) so naturally i went for an upgrade with a full kit from Hertz, 12 inch sub capable of 1000w and Hertz Amp, i also bought a Hi/Low adapter ACV 30.5000-22 ( the lc2i was a little bit expensive for my budget at the moment) and started working. I fed all the cables to the Hertz amp, but now i have a problem, i get no audio signal from the original Canton sub's connector, if i connect the original sub, it works but as soon as i disconnect it and connect the audio cables from the Hi/Low converter to the original connector it stops working. Does anyone know the solution to this? I will leave a few links and photos with everything i purschased for the upgrade and i'm sorry if my english was a bit rough.
