Im gonna buy a big discounted special on amazon $$ . They sell a big stereo subwoofer box with 2 ten inchs drivers that are rated 1200 watt each , and connectors and a powerful amp, all that for 0nly 250$ . im gonna try to construct a 12 volt dc organ with that. you put the speakers in the front of the organ, and you plug the amps and a battery and some ac chargers and then you play it outside as it is too loud for a small house. These speakers can play loud music in a club also for a dj, Hurry my friends, use these powerful 12 volts amps, they consume almost nothing .
