About the EFX PAD8BX Wiring Kit

Power wiring for your second amp

EFX's PAD8BX Core Dual Amplifier Add-On Kit allows you to add a second amplifier to a system without needing to run a new power cable all the way to the battery. This kit's fused distribution block connects to your original amplifier's existing 4-gauge power cable, allowing you to run two 8-gauge cables to supply power to both amplifiers. A 60-amp fuse protects each wire (and your vehicle) from accidental power surges or short circuits.

Power wiring for your second amp

EFX's PAD8BX Core Dual Amplifier Add-On Kit allows you to add a second amplifier to a system without needing to run a new power cable all the way to the battery. This kit's fused distribution block connects to your original amplifier's existing 4-gauge power cable, allowing you to run two 8-gauge cables to supply power to both amplifiers. A 60-amp fuse protects each wire (and your vehicle) from accidental power surges or short circuits.

The 8-gauge oxygen-free copper power and ground cables ensure that your amps get all the power they need for maximum performance. Each ground cable features EFX's Ultimate Ground Terminal, which attaches to your vehicle's chassis by way of 2 self-drilling screws (included) to make sure you get a tight physical and electrically secure ground connection.

This kit includes patch cables for a 2-channel or mono amp — you'll need to add cables for multi-channel amps. This wiring kit does not include speaker wires. You will need to purchase those separately, in order to complete your amplifier installation.

Excellent product. I already had an amp for the speakers. Used this to ad a powered sub. Only additional thing needed for the install was a small piece of 4 gauge power wire and some connectors. Great kit and FAST shipping. Thanks Crutchfield.

Quality product but rusty and bent.

Kennith from Chesapeake, VA on 5/20/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Quality kit and has everything you need to add a 2nd amp. However it looks like this kit was used and returned and resold to me. Not a big deal normally but the terminal connectors provided were bent up real bad and a couple of the screws were rusted. Also was missing one ground wire. I assume it is suppose to come with 2 just as it did power. Plus the picture shows 2 in the discription. I recommend messuring the exact amount of ground you need as this is not a very long ground wire. I barely had enough and had to modify the connection piece to secure it to the OEM grounding spot behind my rear driver side seat in my 2017 F-50. Also you may want to consider buying another splitter for your ground wire.

Pros: Everything you need to add another amp at a great price

Cons: Ground wire is short In my case, bent terminal connectors and rusted hardware. Missing a ground wire. Ground wire end peice needed to be drilled out to fit OEM ground point.

Crutchfield response on 5/22/2018
Our Customer Support rep, Gregory, reached out to Kennith for a follow-up. If you encounter a problem with anything you purchase from Crutchfield, it's important to contact our Customer Support or Tech Support teams right away. They can help you solve the problem or set up a return within 60 days of purchase.

Who doesn't love having all the odds and ends foraged together? Ain't nobody got time for that!

Pros: All the needed wiring lovingly assembled by highly trained honey badgers

Cons: No color options, I guess. I'll be showcasing this the system when complete, but blue happens to fit my theme. Having to sleeve 30'+ of wiring would be a pain

Features

Compatibility: The PAD8BX kit is designed as an addition to an existing amplifier wiring kit (4 or 8 gauge) when adding a second amplifier (each amp rated up to 60 amps).

Kit Contents: This amp wiring kit includes the following:

  • Distribution Block: dual output fused distribution block
    • Input: set screw terminal (4mm Allen wrench not included); accepts a 4 gauge or 8 gauge wire; the input block has three openings (only one is used), so the input wire can be connected to the left side, the right side, or the end of the block
    • Output: both set screw output terminals (3mm Allen wrench not included) accept 8 gauge wire
    • Fuses: a Mini-ANL fuse mounts between the input terminal and each of the output terminals; two 60 amp Mini-ANL fuses are included
  • Power/Ground/Remote Wires:
    • 6' length of 8 gauge power wire in a blue jacket; designed to be cut to the desired lengths and used for both distribution outputs
    • two 2' lengths of 8 gauge ground wire in black jackets; each has the patent-pending Ultimate Ground Terminal for reliable ground connections
    • 6' length of blue turn-on wire
  • Fuses: two 60A Mini-ANL fuses
  • RCA Patch Cable: 17' core-twisted stereo RCA interconnect cable with split-top center pin and segmented shield for maximum contact and connection reliability; twisted pair construction gives you maximum noise rejection for better sound quality; RCA plugs have a micro barrel design and integrated strain relief
  • Connectors: The kit includes the following terminals:
    • four 8 gauge crimp-on spade terminals; 0.35" wide; two with red insulators (power) and two with black insulators (ground)
    • two 18-22 gauge crimp-on spade terminals; 0.25" wide (for remote turn-on wires)
