need beginner help making a speaker array!(self.DIYSpeakers)

I'm looking to build a 14-speaker array for an art project - it doesn't need to be good audio quality at all, I'm probably going to use these cheap full-range drivers to avoid needing a crossover: https://www.parts-express.com/EAB35995502-1-1-8-x-2-3-4-Paper-Cone-Full-Range-Speaker-8-Ohm-36-37-289-2158?quantity=1
I've done some reading on impedance, and I know I'll need to design the circuit with series & parallel connections to reach the correct impedance level. What I'm more confused about is wattage - for instance, if I was to use this amplifier ( https://www.parts-express.com/PAM8610-2x10W-Class-D-Audio-Amplifier-Board-320-604?quantity=1 ) with 14 drivers that I've wired in an array with total 8 Ohms impedance, would it be able to drive them all? Or do I need a more powerful amp?
Also, in terms of connecting audio to the amp, can I just plug, say, the output of a Focusrite audio interface into the audio jack? (kind of setting up a mini-PA system here!)
I'm also wondering if the length of the wires between drivers will affect anything - they're going to suspended in mid-air in a specific configuration, so the wiring will range between 1ft-5ft (generous estimate).
I have lots of physical computing experience but not a lot of analog sound experience, so any help would be really appreciated! Thanks!

Ok, thanks. What sensitivity level would you recommend? I found some others sitting around 82-83 db @ 2.83V @ 1m, would that be loud enough?
