car heater = low voltage?

[myjaja 10+ year member]

Well, today was my first time using my cars heater and might be my last. I turned on the heater and all of the sudden, my music goes out. The stereo kept playing, but I had no music. The music does come back and then go away... it just kept repeating. I have two amps, one for the highs and one for the sub. I'm guessing the amps were turning on and off. But every time the music goes away, the sub makes a boom sound. How can the heater be the cause of this? Did the heater cause low voltage? I would like to try again to check if the amps are really turning off but I'm scared to burn my amps.

Anyone have any ideas about whats going on?

thnx

Have you ever used the AC? The compressor clutch for the air conditioner uses a lot more current than the blower motor on the heater, not to mention the blower motor as well.

You might have a short in the dash.

Your car heater doesnt work like a house heater...there is no heating element, or anything that pulls electricity to make heat.

all it does is cycle radiator fluid through the heater core and a fan blows the heat out of the vents. like helotaxi said, if you can use your a/c or defrost (both turn on the a/c compressor) then you got something going on in the wiring.
