Hello everyone. I’m recently owner of a beautiful Volvo C70 T5 Built 2011. It’s a US import. I have a question about the high performance sound system. I’ve read that this one does not have a center speaker, as it only exists in the premium system. However, I seem to have a speaker in the front panel (see picture). Or is there something completely different underneath?? Second question. I don’t have a subwoofer behind the rear seat. Now I have to get everything and take it into account so that I can connect the original ones of Volvo? Is the current power amplifier enough or does one still have to be switched between the current and the power amplifiers on the subwoofers? Thank you in advance for your answers. LG
