Recommendation for components?

I’d like to build a device that:
-plays an audio file (mp3) at regular intervals throughout the day
-goes to sleep for power savings at night and during inactive intervals
-drives a 20-30W speaker
-runs on battery with solar charging

This device will be housed in an enclosure outdoors for months-long durations. Specifically, it will be collocated with a feeder that will inoculate quail with medicated feed in spring and early summer in the southeast. The mp3 will be a bobwhite quail call to attract birds to the feeder. This is to try and inoculate against parasitic infections that decimate quail.

Possible to get a BOM for Sparkfun products to accomplish this efficiently?

You’ll probably want the mp3 trigger https://www.sparkfun.com/mp3-trigger.html (guide)

Solar panel https://www.sparkfun.com/solar-panel-charger-10w.html

Battery https://www.sparkfun.com/lithium-ion-battery-6ah.html

BMS https://www.sparkfun.com/sparkfun-battery-babysitter-lipo-battery-manager.html

We don’t really carry anything amps/speakers that are more than a few watts…you’ll need to grab those elsewhere, but the above should get you almost all the way there! Add an SD card, usb cable, wires, etc
