Questions about the audio expansion of my latch

Hi guys, now that I’m finally free, I’m probably going to do my long-thought-out plan for the audio expansion of my car.First of all the current location: FS: Standard VW Golf 3 speaker system RS: Pioneer speaker in the hat rack connected to power amplifier with additional subwoofer The following idea is in the room: Throw out all speakers and only one FS with subwoofer in the spare wheel pit. Then as FS Infinity Kappa (each 2 speakers left and right, as Doo rboards in the back of my head) For the current 4 channel power amplifier and another power amplifier for the sub (not yet mentioned for this) I bought 2 identical capacitors really cheaply last year. Can be installed as well. Luggage compartment is therefore disguised and everything is nicely hidden. As far as the theory is concerned. Now the question, what can one think of nem Infinity Kappa FS? Experiences? Is it at all useful to install 2 loudspeakers on the left and right? Seller has m I also advise that I should take one with tweeter and one as a coax system, so that I not only get the tweets from the front/top (meaningfully?) Now the request stands for suggestions and help for further voting in the room. Thanks already
