install speaker in the car

hai all,

i'm new in here...

i would like to ask for a help from all of u in this forum, actually i have a altec lansing speaker model ATP3, n i rarely use it, so i tought that it will be so useful if i install the speaker into my car...

my quetion is, how to change the input power source from 3 pin 24V ac plug and use the power source from car battery that just only 12v. an if u guys have a schematic diagram it will be so helpful..

TQ...

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!

this are the spec for the speaker:

nominal (RMS) output power-27watt
input impedance-10K ohm.
speaker type- 2-way- active subwoofer, passive satelites
response bandwidth- 45-18000Hz

spec info from:
Altec Lansing ATP3 Speaker System :: Articles :: www.hardwarezone.com

i would like to power it using the car battery if it posible, or any other suggestion...

Basically you don't, unless you make an inverter to generate power for it - but it would be a waste of time, it wouldn't work well in a car anyway.

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.
