The first mistake that newbies make when installing car audio is not properly grounding the amplifier. The grounding of an amplifier should be done on the vehicle’s chassis. This grounding should be tightened and scraped to bare metal. It is important to note that seat belt bolts do not have exposed bare metal and are a poor ground for the amplifier. To avoid this mistake, make sure to use bare metal in your car audio wiring.
A voltage drop can also damage your car amp. It will result in poor bass performance as your amp draws more current than your car’s electrical system can handle. As a result, your amp cannot power itself. It will be impossible for your amp or subwoofer to function properly. To check for a voltage drop, you should use a volt meter. A volt meter is a small, digital readout screen that shows the volts of the electrical system in real time.
Before you replace a capacitor, use a voltage tester. Make sure to place the positive end of the tester on the wire connected to the battery. You should then run the tester across the entire system and check each connection point. If you have a bad battery, try checking the distribution block, capacitor, or fuse. If you find the same problem, you should replace the capacitor. It is possible that you have a problem with your amplifier’s capacitor or fuses.
