Poor sounding audiobahn car speakers can be a source of frustration and irritation. The problem could be a result of faulty speakers, carrying out a few tests and checking other parts of the system can help to resolve the condition. If the speakers are excessively damaged or spoil then replacing them with new ones is advisable to prevent the same problem from recurring. On the other hand, some problems might not require that you replace the speakers themselves. This handy guide will help you find out what you need to replace.
Step 1 - Inspect Other Components in the System
Some times absence of sound, distorted or garbled noise or hissing in the speakers can be a result of other components on the system. Start by inspecting the cable that connects the speakers to the stereo and amplifier. Unplug the cable connecting the stereo to the amp but leave the speakers connected to the amp. Turn on the system, if there is still a problem with the speakers then the problem might be the amp.
However, if the system does not have an amplifier, reconnect everything and unplug the cable from the radio. If the noise is still present, then the cable might be the source of the problem. Getting a new cable can resolve the problem in the speakers.
Step 2 - Check for Blown Speakers
To test if the speakers are blown, get a multi meter and set it to read ohms. Turn off the speakers and put one meter lead on each of the two terminals. If the multimeter reads infinite impedance, then the speaker is blown. If it gives a 1.0 reading, then the speakers are in good working condition.
A second method to use includes checking for vibration or thump from a sub-woofer when the volume is up. Turn up the bass and check if the big cones of the car audio sub-woofers move visibly. Place fingers on the speakers lightly and turn up the bass. If there is no vibration or thump then the speaker is probably blown. This will require that you buy a kit that includes the speakers themselves.
Step 3 - Check Grounding
Poor grounding can interfere with the function of the speakers. Make sure all components in the car’s stereo are properly grounded and secured to the chassis. If the speaker is touching ground, it produces a repetitive thumping noise. Check if this is the source of the problem by disconnecting the speakers from the amp.
Identify one speaker that is working positively and connect it to the output in the system one at a time. If the noise persists, them the problem might be the amp. If there is no noise, then reconnect each speaker one at a time. If one of the speakers produces noise during the test, then that is the bad speaker. If poor grounding is the issue, you can purchase a grounding terminal and wiring to better ground your audio system.
Step 4 - Check Cables in the Stereo’s System
Get a voltmeter and check continuity in the speaker cables. Put one lead on each end of the cable and check for interruption. If interruption is detected in a cable, then that is the faulty cable. Purchase a new wiring kit or harness for your car stereo if this is the problem.
