Hello everyone! After I finally managed to buy a radio, namely the Pioneer 6900ib, I also want a little more level from the door boxes of my VW Bora. Do not need the absolute high end equipment. I thought to install two Coax boxes, and also a matching 2-channel power amplifier, which I put nicely in the glove compartment or anywhere else. In total, I thought about 250-300 eggs. How much watt RMS do I need so that d What should I also pay attention to? (frequency, accuracy, depth of installation…) Can you possibly recommend me a certain product? Should I contain the door panel inside? If so, how much? Can someone recommend me to my Internet shop? Are there any questions at once, I hope you can help me. Thank you very much!
