Wifi Audio Amp w/Hifi Active Crossover Network

Looking for an experienced engineer to discuss design of a stereo audio amplifier with wifi as well as a decent active crossover for the already defined drivers.

I posses a base knowledge of system level audio amp design, but lack circuit/PCB level skill set.

Parameters (can be changed if needed):

- Power from a 24V 4A transformer to feed the circuit.

- Power Supply Circuit (~200W)

- Wifi Audio Circuit (discussion will be needed)

- Two Biamplifed Active Crossover Circuits

-- (trying to emulate: [login to view URL])

- Pre-Amp Circuit (possibly)

- Power Switch

- Pre-Amp Input

- RCA Input

- RCA Output (line level)

- Aux Input

- Input Switch

- Gain

- Low-pass/high-pass gain

- Left Output Woofer (4 ohms, 20V RMS,40 Max)

- Right Output Woofer (4 ohms, 20V RMS,40 Max)

- Left Output Tweeter (6 ohms, 15V RMS)

- Right Output Tweeter (6 ohms, 15V RMS)

Very new to audio over wifi so will need direction as to how to go about the design.

I will simply need a circuit sketched up with requirements and part suggestions. I will work on sourcing PCB's and parts (unless this can be done seamlessly).

Looking forward to hearing suggestions!

I've done it all before - even the WiFi. Modules are the way to go for prototype. I would like to clarify how you want the WiFi (or Bluetooth) part to work -- as a transmitter or receiver?
