i hooked up this amp im gettin....its a rf 400s. well...aparently it killed my battery cuz after i left it parked at night it wouldnt start in the morning, or any other time i tried to start it after driving. so i went to autozone. said it was bad. got a free one cuz of a warrenty.

but this is gonna be the amp im runnin for a while. and i dont wanna get a battery every week. what could i do. ????

 

What did you use as the turn on lead? The blue wire from the deck, or one of the vehicles constant power wires? If you used a constant wire, did you connect a switch?

 

Could it be that your alternator isn't charging your battery?

 

i usaed the remote wire from the head unit, this isnt the first one ive wired, my alternator is fine, just put a new battery in and its good, just dont want the amp to mess w/ it again.

 

sounds like a charging problem and am that small would not kill any car battery......

 

well im gonna hook the amp back up again and see what happens. i can get free batterys whenever i need them for the next 19 months so ill just go get another one if i need to. until i can find out if its my alternator.

 

maybe u left ur light on

 

ehh, dont think so, if the batt. died, wouldnt it have recharged?

 

bahhhh it happened again, what to dO! get my alt. checked?

 

yes, get your charging system checked out - but more importantly see if your amp is staying on when the car is off! theres a possibility something is draining current - batteries just don't die without a load on them when parked.

-rage

 

well i never had the car turned off...only running when i had the amp, cuz its not even mine yet. i borrowed it. but i dont see why it wont charge after the amp cuz i left my lights on the other day for like 4 hours and it started. barely, but it did.and recharged fine from that.

 

Most likely the battery was just old and needed replaced. Doesn't mean there's anything wrong with the charging system, just the battery died.

 

Here's a couple things you can try:

1. Disconnect the amp and see if you have the same problem.
2. After starting the vehicle, disconnect the battery's ground cable - the car should
still run since the alternator is powering the car's electrical system. If the car
dies, then you know you have a problem with the alternator.

NOTE: Once a battery drops to a certain voltage, it will never reach a full charge
again. Deep cycle batteries can but starting batteries will not.

 

Put an ammeter inline inline between the positive terminal of the battery and the cable going to it. If you see more than 300 to 500mA then something is pulling too much current. Do the same with the amplifier's positive lead and make sure it is powering off properly.
