Have you ever known troubles with finding your car speakers to work? Whenever your speakers are also not working, I suggestion that you test the auto speakers that don’t work directly:
• Disconnect each speaker that doesn’t function from the car’s cables and do the trial below, doing one at a time.
• Apply a 9v battery and connect its leads to each auto speaker to be tested for a short moment.
? Does the speaker have move?
? Do you hear the sound commonly recognized as a ‘pop’ or thump?
Whenever your results to the questions above are ‘yes’, your speaker will perhaps be capable to make sound and it is probably to work.
• Also note which method the speaker are moving, whether in or out of its frame during the exam. Thus you are able to still determine your auto speakers’ polarity when connecting them up to the amplifier up in the front.
• Whenever the cone of your speaker takes out of the basket, the lead attending the positive of the battery is the positive lead of the speaker. Whenever it goes in the different direction, the lead hooked to the minus of the battery is plus of your auto speaker.
