Hello everyone,
I've been thinking about building a Bluetooth speaker lately.

There are a few components in this setup:
USB Powerbank: powers the Bluetooth receiver and PAM8403 amp.
Bluetooth receiver: receives signal from bluetooth devices like my Galaxy S4 or laptop.
PAM8403 amp: receives a filtered signal from the Bluetooth receiver. Right channel goes to the woofer and left channel to mid/high range speakers.
How do I make a low-pass and high-pass filter with a cutoff frequency of around 150/200hz? My plan is placing it between the Bluetooth receiver and PAM8403 amp so the amp amplifies the low-pass on the right channel and the high-pass on the left channel.
Regards,
Nando
