Distribution Block Type
This specifies what the intended use of the distribution block is. Fused distribution blocks are intended to be used with the power wire and the fuse acts as a short-circuit or surge protection so your amplifier is not as likely to be damaged. Non-fused distribution blocks can used with ground or power wire connections, but the protection on power wire connections will not be present as there is no fuse in the distribution block. Therefore, we recommend your amplifier has an external fuse for short-circuit or surge protection. When using either type of distribution block, it is recommended to use a main fuse holder within 18 inches of the battery.
Fuse Type
For accessories, this is the type of fuse that is required for the item to work properly.

For fuses, this is the type of fuse.
Number of Fuses
This is the number of fuses that the item requires to work properly.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Maximum Output Gauge Size
This number refers to the maximum size of wire that will fit into the output connector(s) of the capacitor, battery terminal, or any other connector with an wire output.

    FAQ Frequently asked questions in Discontinued Distribution Blocks

    Car Amp Distribution Block Frequently Asked Questions (FAQ)
    A car amp distribution block is a crucial component in a multi-amplifier car audio system. It serves as a central hub to distribute power from the main power cable to multiple amplifiers. By using a distribution block, you can simplify the wiring process, reduce cable clutter, and ensure each amplifier receives the appropriate power supply. This setup is particularly useful for high-powered audio systems, as it helps maintain stable voltage levels and prevents voltage drop, ensuring optimal amplifier performance and efficiency.
    When selecting a distribution block, consider factors such as the number of amplifiers you have and their power requirements. Choose a distribution block with enough terminals to accommodate the number of amplifiers you plan to connect. Additionally, pay attention to the size and gauge of the power and ground inputs, ensuring they match the power cable you are using. Look for distribution blocks made from high-quality materials, such as copper or brass, which offer excellent conductivity and durability. If you are unsure about the appropriate distribution block for your system, consult with a car audio expert or refer to the manufacturer's recommendations.
    Installing a car amp distribution block is a relatively straightforward process, but it requires precision and attention to detail. Start by disconnecting the car's battery to prevent electrical accidents. Next, determine the ideal location for the distribution block, ensuring it is easily accessible and away from potential hazards. Connect the main power cable to the input terminal of the distribution block, and then use separate power cables to connect each amplifier to the output terminals. Secure all connections with appropriate crimp or solder connections and cover them with heat shrink tubing for added protection. Once all connections are secure, reattach the battery and test the system to ensure proper functionality.
    Yes, a car amp distribution block can significantly improve your audio system's performance, especially in multi-amplifier setups. Without a distribution block, attempting to power multiple amplifiers directly from the vehicle's main power cable can lead to voltage drop and uneven power distribution. This can cause fluctuations in amplifier performance, reduced power output, and even potential damage to the amplifiers. A distribution block helps maintain stable voltage levels to each amplifier, ensuring consistent power delivery and enhancing overall system efficiency. As a result, your amplifiers can perform at their best, delivering clean and powerful audio signals to your speakers or subwoofers.
    Yes, there are different types of car amp distribution blocks available to accommodate various audio system configurations. The most common types include single input, multiple output distribution blocks, and multiple input, multiple output distribution blocks. Single input blocks are ideal for connecting a single power cable and distributing power to multiple amplifiers. Multiple input blocks, on the other hand, allow you to connect separate power cables from the vehicle's battery or alternator, providing dedicated power feeds to each amplifier. Additionally, some distribution blocks come with additional features, such as fused terminals for added protection, LED voltage displays, or built-in grounding points. Choose the type and features that best suit your audio system's needs for a clean and efficient power distribution setup.
