Video of my Homebrew Electronic Q.

Siren consists of a 600 watt PEP stereo amp, a cheap MP3 player, and 2 - 1oo watt siren speakers.
Amplifier is fed with an MP3 player with 45 minutes of a recorded Q looped. Amplifier out put is mono bridged with RMS output of 240 watts.
Since the speakers are 11 ohms and run paralell, the speakers are 5.5 ohms. Since the amplifier is a 4 ohm output to the speakers, it will handle the 240 watts.
Sorry for the second post, I forgot to check the NOTIFY ME box on the original post
