Hello. I'm installing new speakers in my 2020 Superb iV and wanted to ask the experts here for advice on speaker connections. I apologise if the solution is obvious, I'm a little new to car audio :)

The speakers I'm installing are HELIX Ci3 K165.2FM-S3 from Audiotec-Fischer. Looking at the manual, as attached, I'm supposed to connect the tweeter to the physical crossover as well as the midbass, and from the crossover a single wire to connect to the signal source. 

But when I removed the door card and inspected the wiring, it seems both the stock tweeter and midbass have individual wires running into the door separately. I can't see if there's a crossover installed somewhere else but now I'm wondering how I'm supposed to replace the whole thing. 

I can connect the new tweeter to the wires already installed to the stock tweeter and do the same thing with the midbass but that would leave out the crossover, and I'm worried that would be the wrong thing to do. 

Thanks in advance for all advice!

I don’t know for certain and I’m sure someone will correct me if I’m wrong. But the car should have its own crossover to sort out the signal to the speakers. So if you use the OEM wiring directly onto your speakers and leave out the aftermarket crossover one would assume that it would work fine. That’s what I would do anyway! Doesn’t mean it’s right though!

Indeed that's what I've been thinking. I also wonder if I should just use the midbass wire to connect to the crossover, and leave the OEM tweeter wire disconnected?

The vehicles do not have a crossover from the OEM. Do you have three speakers per front door? If the vehicles do not have a factory-installed sound system, the frequency is split using a capacitor at the speaker. If the vehicle does have a sound system, the digital sound processor is located under the driver's seat (in the case of left-hand drive vehicles). This processor directly powers each speaker and is operated via coding and a data set at the sound processor.

I recently did the work for someone with a Superb hybrid 2020 sound system without a subwoofer to find out the pinout.

Thanks for the reply. Sounds like you were working on a vehicle with the Canton system? Mine has the base sound system, only two speakers per door and no amplifier. I've added a DSP amplifier and now I'm replacing the speakers :)

It also doesn't have an original crossover.
