I'm splitting a ~2w RCA signal to 4 sets of plugs. Yes, I know ~2w hardly tells the story of my audio signal, but I'm using a USB Optical>RCA DAC purchased for cheap on eBay, sadly it doesn't list the outspecs of the DAC... All I know is that it pulls 500ma @ 5v via ammeter.
Basically, my setup is as follows:
RCA 1 + 2 > Power Amp (A/B) R, L Mid/Tweeter Crossover.
RCA 3 + 4 > Power Amp (A/B) R, L Channel 10" Subwoofer Cones.
RCA 5 + 6 > Second Power Amp (D) 15" Subwoofer Channel.
RCA 7 + 8 > Spectrum Analyzer.
Now, the spectrum analyzer isn't sensitive enough to pick up the heavily split signal. Unplugging the amplifiers rectifies this issue and the SA works flawlessly. I'm wondering if putting a cheap 3w USB amplifier in-line with the spectrum analyzer will greatly mess up the rest of the sound stream.
I'll be using a cheap ebay module

I'm wondering if it's going to mess up the RCA signal path since it's connected to the same case ground / RCA negative connections as the rest of the system (the amps have their own grounds too)
Anyone have any suggestions/input?
