Hello. Plan a small upgrade for my Astra F level with regard to sound technology Will install these speakers in the front of the doors (Ground Zero Titanium GZTC 13MK2)http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=300024146093 In the hat rack they should find their place here (Ground Zero Titanium GZTC 16MK2)http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=300024146101 As “engine” for the whole I plan the here (Audiobahn DUB 1004)http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem& item=4645614761 Can I mount the components like this or do you have any objections? Would you like to install new cables for the speakers or can I continue using the old ones? If new ones have to be pure: does it also have to be simple 2.5mm2 from the control cabinet construction or does it have to be this very special expensive cable? Are the 8mm2 sufficiently dimensioned at the power stage? MfG, Astra-Tino
