Moofs Posted August 24, 2010 Report Share Posted August 24, 2010 I recently got a sub and amp installed in my 94 toyota corolla. The amp makes 240 watts rms and I have a clarion head unit speakers but the speakers r running off the head unit. I turned my car on after the dentist today and the battery light is on and I have no power steering. Do you think my system is draining the battery? I only listen to it when the car is fully on and driving. And I don't slam my subs. I listen at medium volume and my sub is tuned at a decently loud level at the zero on my headunit. I usually set it at -3 on the bass setting. What could this be?

ingramcaraudio Posted August 24, 2010 Report Share Posted August 24, 2010 Check the connection on your battery terminals if that isn't the problem check your alternator chraging voltage.

Bumpin the TWP Posted August 24, 2010 Report Share Posted August 24, 2010 its probably not your system. you probably just have a bad battery, also could be the alt.

Moofs Posted August 24, 2010 Author Report Share Posted August 24, 2010 I'm really hoping its the battery. Just about 5 months ago or so we replaced the alternator with a new one, still factory, but it was new. So could it be anything else?

skittlesRgood Posted August 24, 2010 Report Share Posted August 24, 2010 check the amps and make sure they turn off when you shut down the car. make sure you dont have a short somewhere, it could cause a fire. double check wiring behind the HU. some wire harnesses with the door chime will drain the battery just because they were poorly made.

Guest Posted August 24, 2010 Report Share Posted August 24, 2010 i also have a 94 corolla and i was drawing damn near 1000+ rms on the stock alternator and it was fine. chances are its the battery or the terminals arent clamped down enough (aka loose) Quote Link to comment Share on other sites More sharing options...

As in fuses? And i dont think I have a dorm chime? at least I dont think, unless you mean the "chime noise" that goes off if the door is open, but thats only if I leave my keys in the ignition when I open the door but I usually have them out by then.

UnderLoK Posted August 24, 2010 Report Share Posted August 24, 2010 (edited) I would assume it's the battery or the alternator. Start the car with a volt meter on the battery and look to make sure you see a rise in voltage (13+ volts). If you don't, turn up your stereo and within a minute or so you should see the voltage rise, if you don't your alt isn't charging. This could be from a dead alt, messed up wiring (loose wire on the alt or in the alt harness), etc. If you do see it charge then take your car to an Auto Zone and have the battery tested. Your stereo shouldn't be completely killing the battery. Could it? Yes... But only if something else is wrong (as others have brought brought up). For now I would stick to the obvious, battery or alternator (that is unless you just put your stereo in a day ago or something).

Or at least the sub and the amp.
