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! Cheers.
