hi guys! i was a newbie before i installed my 700w amp and subwoofer enclosure in my car. thanks to some of your guys help and this website i managed to install it beautifully! however.. a few months down the line and ive gone through 2 car batteries cos the amp has sucked them dry or whatever. Someone suggested WIRING THE AMP TO THE ALTERNATOR INSTEAD OF THE BATTERY! now it sounds good in theory... i have a voltmeter so any tips on how to go about it? i´d appreciate any help!!!

No, it doesn't even sound good in theory, either.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

ok so why wouldnt this work? it would really feed off the alternator instead of the battery, so only when the car is on. Or is there another economical solution since my batteries went real fast. they died.

Well, connecting your system to you alternator is not really an option. Your alternator is connected to you battery which means that you really can't bypass your battery. Even when your car is running it uses the battery in addition to the alternator. Take a look at the wiring on your system and the only wire that really feeds into you alternator is your battery wires.

So, your best out is the check your charging system to see if it is functioning properly and not burning out your battery.

Your amplifier cannot "suck your battery dry" unless there is something wrong. Either it is drawing current when you have the engine off, or your charging system is defective or too small. Do your lights dim when you drive at night and play the system? Sound to me like you need a new alternator and/or voltage regulator, or you have a problem with the install or the amp itself...
