Moin Moin dear people, nice to be with you now! I just bought a Seat Arosa Bj. 99 6H 1.0 A great coach The defective loudspeakers gave me the reason to design a clever music solution for it. Unfortunately, I don’t really know about it. I bought the GTO 939 loudspeakers from JBL for a bit longer time. 2 pieces. And I have the KVI 700 radio from Kenwood. http://www.conrad.de/…tsprecher-Set-300-W-JBL-Harman-GTO-939?…http://www.k enwood.de/…/?view=details I would have put the JBL GTO 939 in the hat rack or is that bad? The car has a speaker in the door 16cm diameter on each side and a smaller one on the front behind the steering wheel on each side. Would be nice if you could suggest something to me. And above all tell me what I need and how about I should realize. I had already informed myself but became uncertain and confused also whether I need power amp or not etc. Vie Thanks already in advance! And nice greetings from the beautiful Hanseatic city of Rostock Your Malik
