Moin, we’ve been looking for our Volvo V90 Inscription(04/2018) probably next week and I wanted to replace the speakers, as well as a subwoofer and amplifier. I’ve been looking for a long time here in the forum and found nothing suitable so far. 1. How can I remove the door panels, so far no guidance found. 2. I’ve read that the amplifier in the standard sound system is under the passenger seat. It’s been asked again if that’s what it is, as an answer came only that it is generally known. So I don’t have this knowledge, is that the amplifier under the seat? 3. If someone has a connection plan from the amplifier, then you don’t have to measure it. 4. I’ve read the Volvo using a Most Audio system, it’s supposed to be stubborn. Is there maybe amplifier that can handle it, or suitable adapters? 5. The subwoofer should be hidden a below the driver seat or. The passenger seat should be matching system. If there’s probably enough space then if the seat has gone down and someone who could recommend it to me? In the Reserve Mulde we don’t want to build a subwooer, because we’t have the driver’ve got the next to say that the speaker?
