We need alot more information to work with!

What are you powering it with?
What is the speakers wattage and ohms rating?
Any other info is also very helpfull too!

According to the operating manual, the speakers require either 120VAC or 240AC depending upon the model you have (you said 24VAC so I assume you have the 240VAC unit). Thus you would need an inverter to generate that power from the 12V car battery. These can be readily purchased.
