Moin, I’m going to improve the sound a bit in my Swift. Unfortunately, I don’t know about speakers and subwoofers at all. So I hope for your help. So I have a 2007 Swift Sport and would like to install a subwoofer so I have more bass. Does it make sense to install only a subwoofer or should I switch the speakers directly in the front? Does this all work with the original radio or is it already a bad basis? adio already make sense or? I think just because of Bluetooth. I thought so about about 550€ for the construction. I already insulated the doors and the trunk with aluminium butyl and acoustic foam. Are there other places that you should definitely contain? Can someone please tell me what exactly I need and with possibly something nice to put together? Best then directly with the links. Would I be happy if someone answers.
