Hello everyone. So I bought a car again after a year of subway and bus driving. The car is only a Golf 3 but the system is supposed to be the hammer. With each car my system gets better and this is like me the coronation. So then I start: 1) I had thought of this subwower: Hifonics GX 2412 12的 30 cm SPL Subwoofer 4.800 Watt Hifonics GX3215 15的 (38 cm SPL subwoofer 6.400 watts Problem: What kind of power amplifier do I need and what kind of housing??? 2) Boxing: So I bought a car again after a year of subway and bus driving. I want at least 2 in the storage. 2 in the front door and 2 so anywhere at the cokpit or something. What is there and it lasts well. 3) The radio: I had thought of a radio with DVD, TV and Navi in one there is something like that??? If so what is there good??? I think that all should be :-))) I hope you can give me good ideas all the more the better 🙂 I thank you already in advance. P.S. if you have offers then send me the link right away with that would be nice thank you .
