Need an AMP/mp3 player kit for paint splash photography

Hi Guys,

I am an amateur photographer currently working on paint splash shots using high speed flash controlled by a homemade Arduino piezo vibration trigger. (Sample image below using current set-up)

Although I know my way around my camera, I understand almost nothing about audio. My shots so far have ben created by stretching a balloon over a 4” speaker, 5W 4 Ohm, and sound provided by an old Alba CD player. The speaker was removed from one of the Alba cabinets (plastic box).
The sound source is an mp3 file of a 50Hz square wave sound created using http://onlinetonegenerator.com/

My problem is that I think I need a bigger speaker with more oomph/volume! I am thinking about 6” 20W perhaps? OK, they’re available cheaply but what do I use for a power source? I see some cheap amps as kits but what do I use to play the mp3.

As onlinetonegenerator is an online ap I tried plugging my phone into the Albas AUX port so I could work on/adjust tones on the fly. Results where pathetic.

My ideal would be some sort of kit form mono-amp with somewhere to plug a memory stick into. Any ideas, does such a thing exist (without buying a complete audio set-u[)? Sound quality unimportant only for “playing” tones of various frequency.

Can any body point me in the right direction?

Cheers,

Eugene
