Hello! So, I'm not sure if this is the right forum to post this, but I hope someone can give me some insight.
My Dad's Projection TV died recently and we had the idea of removing its 16-speaker array to reuse as a sound bar (pic 1). After opening up the TV and reading the maintenance manual I found online it seems that the 16 speakers are driven by 8 tpa2017d2 stereo amplifiers that are fed by 2 pcm1681-q1 DACs (pic 2 and 3).
I was thinking of removing DACs from the PCB and tapping into the inputs of the tpa2017d2 amps with a single stereo RCA input. Thing is, I need to duplicate the signal 8 times to have the same signal going to all amps. Is there a relatively simple way to do this?
As additional notes, board is powered by 12V that I would provide externally and while I thought of daisy chaining and plugging the speakers into a regular AVR, I'm thinking the parallel impedance would become too low for it to handle?
Any insight would be very appreciated! Thanks in advance!
