Unconventional Stereo System Issues

So, earlier today, I encountered a really catastrophic issue regarding my unconventional stereo system. I connected my Victorola TT to a phono pre-amp with a red/white RCA cord, then I connected my pre-amp to my head-amp with an RCA > AUX splitter from the two RCA ports on my pre-amp to the single 3.5 millimeter "AUX IN" port on my head-amp. I, fortunately, heard the TT playing the record, although at a very low clarity but, after I attempted to use the head-amp with which both of my SOUNDBOKS 2 speakers are connected, in order to play music from my computer through a Bluetooth adapter inserted into the "AUX IN" port, I encountered the dreaded of issue of hearing absolutely no audio.

To provide some context, the exact same issue arose with my last head-amp of the same design, so I decided to order another one. After the first blow-out, I determined that the cause of the issue was the incredibly low-power phono audio signal, being far weaker than a digital signal, causing my battery to malfunction. After performing some research, reading the description of the page of the head-amp which states that it converts phono to RCA signals (and I, at the time, presumed that RCA could be converted to a digital signal with a splitter due to what I'm about to say), in addition to consulting with a friend of mine, and finally, making a post on a supposedly 'audiophile' forum on which someone, with great confidence and belief in their own veracity, told me that the arrangement would function, I decided to do what was said in the first paragraph. So, needless to say, I'm very desperate for someone with actual experience, diligence, and honesty to inform me of whether my new plan if implemented, will yield successful results. Of course, I appreciate any effort in regards to helping me resolve my issue but, if you're not confident that it will be successful, then I'd prefer you to mention your uncertainty in order to prevent the aforementioned situation. I've spent hours researching this topic and I still find it highly complicated and confusing, unfortunately.

My new plan consists of connecting the TT to the phono pre-amp with RCA cables, connecting my phono pre-amp to my Rockwell Equalizer with RCA cables, connecting my Rockwell Equalizer with RCA cables to my ADC, and, finally, using a Coaxial > 3.5-millimeter AUX cable inserted into my head-amp. I would also like to know if it's possible for me to successfully use a CD Player, or Cassette Deck, in substitution for the TT with the same linear components of the plan above followed. Thank you for taking the time to read this in advance, and I would like to use this forum more in order to gain more understanding regarding the audio world as I do find it interesting.
 
The phono preamp steps up the turntable signal so it can be played through a regular input, this should play fine into an input on your headphone amp.

I'm not really sure why the Bluetooth adapter or where that comes in.

Are your speakers powered? It may be the headphone amp will only output to one output at a time.

I'm well aware of that and that's, essentially, the basis on which I decided to use RCA cables to connect my phono pre-amp's output to my headphone amp's input. Unfortunately, that wasn't the case and I'm still absolutely confounded.

The Bluetooth adapter is used as a means to connect my computer to the headphone amp with which both of my speakers are connected together.

Yeah, both of my speakers have amps and pre-amps; the former of which is quite powerful in consideration of the fact that they can output 122 decibels; they're party speakers. No, I've confirmed that both of my speakers are completely compatible with the FiiO A3 head-amp due to them functioning immaculately with them. Not to mention that a video, produced by the company that produces the SOUNDBOKS 2s, advertised the FiiO A3 headphone amp as a means of connecting two SOUNDBOKS 2 speakers.

I'm most concerned with determining whether the Analog to Digital converter will prevent the phono signal from making my head-amp dysfunctional.
