Be careful not to hit and damage other components like the fuel tank while drilling and screwing.<\/li>\n\n\n\n<li>Begin to work with wires by disconnecting both the negative and positive cables from the starter battery. This should be followed by unbolting or cutting off the wire connecting the alternator to the starter battery. Make sure to unsnap the negative cable first and then proceed to the positive one.<\/li>\n\n\n\n<li>The next step is to connect your battery isolator. After disconnecting the alternator wire, connect it to one of the isolator\u2019s side terminals. Fasten an extra wire to the central terminal of the isolator and connect it to the alternator. This wire reaches the battery\u2019s positive terminal.<\/li>\n\n\n\n<li>Proceed by connecting the wire that runs from the starter battery\u2019s negative cable to the negative terminal of the auxiliary battery.<\/li>\n\n\n\n<li>Continue by grounding the second battery. Give a wire connection from the second battery\u2019s negative terminal to the chassis or other metal ground.<\/li>\n\n\n\n<li>Continue the process by connecting your amplifier from the second battery, attaching a red 4-gauge wire to the secondary battery positive end to route it to an amplifier fuse, and then attaching another red wire from the fuse to the amplifier.<\/li>\n\n\n\n<li>For safety purposes, make sure to cover all the positive end connections with a cap to stop any shortages or sparks that may be generated from the battery.<\/li>\n\n\n\n<li>Conclude the setting up process by giving a final and thorough check. Verify all the connections properly as a wrong connection may lead to a short or problems starting the car.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How Long Does a Car Audio Battery Last?<\/h2>\n\n\n\n<p>If you are using a standard car battery, the radio can run for 8 hours before the car battery runs out. If your car is additionally packed with amplifiers and subwoofers, the battery may run out after 6 hours. <\/p>\n\n\n\n<p>Older versions of car radios without amplifier facilities can draw 0.25 amps to 1.5 amps.&nbsp;<\/p>\n\n\n\n<p>If the car battery capacity is around 40Ah, it can last for a few more hours at lower volume levels. Modern car stereo systems can draw 1.6 amps and more, even with low volume. Playing music at maximum volume can draw above 10 amps. <\/p>\n\n\n\n<p>If you use a battery capacity of 40 amp-hours, it can operate for 4-8 hours with maximum listening before running out.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Are The Disadvantages of Having a Car Audio Battery?<\/h2>\n\n\n\n<p>There are however some disadvantages of instating a car audio battery and we would like you to be aware of them before you make a decision.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Additional Load on Alternator<\/h3>\n\n\n\n<p>Your car alternator is used for charging your regular car battery but if you install a car audio battery it will overload your alternator which could potentially damage it. <\/p>\n\n\n\n<p>Upgrading the alternator to match the power rating of your system and the overall drain could be a solution.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Additional Space Required for Car Audio Battery and Kit<\/h3>\n\n\n\n<p>Car audio batteries are usually large in size so they need additional safe space. Car audio batteries can be safely installed in the car boot but unfortunately, that takes away from the car storage space.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Additional Weight of Car Audio Battery<\/h3>\n\n\n\n<p>Even when the car audio system is not in use, the car has to carry the weight of the battery, resulting in additional wear and tear and degrading the performance of your car.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Additional Cost of Installation<\/h3>\n\n\n\n<p>Car audio installations that include a car audio battery mean that you have opted for a high-end audio system.
