This was filmed in 2011 with a mobile phone, so sorry for the bad quality. A PC power supply was used to power the amplifier and a CPU heatsink to cool the integrated amp circuit. The amp is still working perfectly at the time of uploading this video and is powering the "dual coil" speaker that you cand also see in one of my videos and two other smaller speakers.
