Hello dear forum! I bought an old Porsche 924 Bj:83 on Friday. In this, however, still the radio reception antenna, a radio and the loudspeakers with cabling are missing. Now I have to go to the search on the Internet, but admittedly white is a bit overwhelmed. Whether now a 2-way Coax system is enough, or rather invest in a 4-way system? A whole complete package with subwoofer, amplifier and amplifier or better to be a professional? I am less skilled in craftsmanship, but I have enough acquaintances who are familiar with it. But unfortunately only in the installation and not in the consultation What is important to me: I want a nice sound, which also gives enough bass. In the car 4 positions are intended for a box assembly, that’s all I want, because I don’t want to change anything on the car itself. On the radio my requirements are relatively low. There are the only prerequisites an AUX and/or USB connection. The boxes are my s knowledge elliptical shaped and have the dimensions of 4×6 inches. I would like to spend about 300-400€ I am grateful for every answer and recommendation.With 2 more products I have looked at so far..http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=11259588919http://www.just-sound.de/…/
