Hello together I drive a BMW E46 and would like to get a bit more out of it than with the original audio system. Unfortunately I don’t have the biggest idea about it, I know that you need an amplifier for a woofer but if it is for example also about to clamp an amplifier to the boxes I have to fit unfortunately I already have some devices in stock or I would get it from a colleague Radio: Sony CDX-GT565UV 52×4 Watt Amplifier: Blaupunkt GTA 460 Channel 800 Watt or Crunch GTI750 Monoblock 1 x 200/375 Watt RMS @ 4/2 Ohm 1 x 400/750 Watt max. @ 4/2 Ohm Subwoofer: Crunch GPX10BP 600 Watt max. 300 Watt RMS Hifonics BX12 800 Watt max. 400 Watt RMS Capacitor 1 Farad These are the things I could install immediately, are they good for something? Which loudspeakers would fit with amplifier or without? Unfortunately many question marks over my head at the moment :/ I also made a kind of sketch as I imagine and possibly can d he pros here repair my mistakes and errors Sorry that I am here as a beginner with from your point of view probably doofen questions on the mind but I don’t want to somehow suffocate myself and perhaps build up parts that do not harmonize or even damage something among each other. mfg
