Question about Sony Xplode P5 Turbo Subwoofers Car Speaker
Hello again empsglen,
"If the sub voice coil is open, you will get exactly no sound. No crackling, nothing.
Use a multimeter to check the sub voice coil. If the meter reads infinity, the coil is open and to the amp, it's as if there's no sub connected, and you will need to replace it."
Sorry about that.
OK, my clarification assumes that you know how to set a volt-ohm-milliamp (VOM), or multimeter up to measure ohms, and that you have such a meter or have access to one.
The voice coil is the part of your sub that connects to the amp output and causes the cone to move in and out in response to electrical signals. If it is open (broken, burned) there will be no electrical flow and the cone will not move. A good voice coil will read a resistance (impedance) on the multimeter. If the coil is open, the meter reads as if it wasn't even connected (infinity) and if the coil is shorted, the meter reads zero (dead short). Simply put the meter across the speaker terminals and read the results.
