Quote:If I also install BW amplifier,I will need to swap every time I go to dealer correct? Is the car somehow logging the install or swap or won’t “know “it ever happened?Yes or simply disconnect the power or the MOST cable. The car does not log anything about the ECU swaps. When VIDA is connected to the car, it performs full readout of all existing and installed ECUs and compares the HW part numbers, software numbers to the VOLVO DB.
Quote:BW speakers have some capacitors on the mid and tweeters but none on the woofers.Yes, both gen1 (before 2023) HK and B&W AUDs have has one crossover. Two channels (high and MID + HIGH) on the front doors.
Does it mean the woofer is the only one with active crossover from amp?would make sense as tweeter and mids are in parallel and share one output,so need a passive crossover to work properly.
Rear doors are differ between 60 and 90 series.
HK MID speakers does not have capacitors but if I recall, tweeters do have. The main reason of those capacitors is to stabilize voltage and smooth out power fluctuations and not necessarily to filter out audio frequencies. Filtering is done on the AUD already.
Quote:Is the midrange output from amplifier at full output frequency?No, it's only from MID to high.
Quote:Should I consider the aftermarket speaker route instead?or BW will be superior in terms of sound quality?Aftermarket center dash speakers are starting from $250! with the trim. If you are not going with full B&W instead you will be using some other brands, than Aftermarket center dash makes sense. Audio quality is not at the same level as B&W but much better than the HK one you have. However, the trim piece that it comes with is very low quality with flows.
