What is the best PA system for a car?

Whats the average charge for having a pa system in your car?

• Answer:

  Well, you can spend as much as you want. You can buy as many amps, speakers, and deep cycle batteries to run the thing as loud and long as you like. However, you may not need all that. To get started, you need a mic, a receiver, and a speaker or two for the outside. Hook all this up to the battery, flip on the mic, and Voila. Speakers, or a horn, mount it/them under the hood somewhere. http://www.radioshack.com/product/index.jsp?productId=3229236 http://www.walcottcb.com/spc15r-pa-horn-speaker-25-watt-p-114.html?cPath=221_32_402 Receiver & Microphone, the easiest way is to buy a cheap CB radio as you get both, and it is pre-wired to 12 volts so it runs right off the car battery.

Otherwise, remember to upgrade your battery if you are going to be using this at stoplights and such. When your alternator is not at high RPM it is not making electricity. A battery is only a storage tank, it doesn't make power. A bigger tank smooths out those peaks and valleys in the charging cycle due to more/bigger electronics. Here is a big list of batteries available. http://www.bdbatteries.com/allbatteries.php Runtime is measured by; watts x hours = amphours x volts You know how long you want it to run (hours) You know the volts (12v) You know the watts (based on radio and speaker) Solve for AH and you know how fast you drain the tanks.
