Hi,

I'm new to this rasberry pi scene but I want to create a rasberry pi pc as an in car head unit. My car is a small 2 seater, it has a head unit that provide 2x25watt to a 2x100 watt bose amp that goes to two bose speakers.

I was wondering If I can just wire the amp2 directly to the bose amp? 

Also, I know I will need a circuit protection. I was planning on using an inline fuse. What amp fuse should I use to protect the amp2?

My setup is-

*Rasberry pi4 4gb

*Mausberry 4amp car switch

*hifiberry amp2

*7" rasberry pi 4 touch screen

  If you already have an amplifier, you don't need another one. The DAC+ is the right product in this case.

  Oh man, I already bought the amp2. Plus I kinda want to keep it similar to the factory setting. Since the factory head unit has 2x25 watt amplifer that goes to the bose amp. I kinda want to keep it that way. Would the amp2 still work since it has 2x30 watt? In theory it should work, if not ill buy the Dac+ and use the amp2 for something else. But I still want to test the amp2, what amount of amperage can the amp2 handle before it gets damage? I'm trying to determine what size inline fuse I should use.

  I don't think your amplifier is connected to the amplifier outputs, but to a line-output on your head unit.

  I don't knopw any amplifier that is designed to work with the output of another amplifier as the input. There's a good chance that this might damage your amplifier if you try this. However, I don't know the system you're using. Therefore I recommend to contact the manufacturer and ask him what input signals are supported
