I... I just. I've been driving around with my bluetooth headphones for the last eight months because I had already gotten one of those crazy expensive h/k replacement amplifiers about a year and one half back.

Half my mind tells me it would be more cost effective to purchase a good multi channel and high bandwidth oscilloscope, map the circuit, and PCBway a new amplifier and just properly document an alternate solution to the h/k audio system in the first generation minis. I don't particularly love that it's just commonly accepted that, "no u cant do tht h/k only besides its literaly so good y do u want to replace" is the only answer. If anyone has compiled a list of resources, vehicle wiring diagrams, *specific* information as to why this audio system is so unique etc etc pls I have only time to offer and a God[the h/k system] to kill.
