1/0 Gauge Input to Triple 4 Gauge Output Power Distribution Block

The DS18 DB1034 is a high-performance power and ground distribution block designed to split a main heavy-gauge power wire into three separate 4 AWG output lines for multi-amplifier car audio systems. Built from solid brass with a corrosion-resistant nickel finish, it ensures high current delivery with minimal voltage loss. Enclosed in a durable, heat-resistant protective cover, the DB1034 provides a clean, reliable, and secure connection for high-output automotive audio installations.

  • Triple Output Distribution: Easily splits a single 1/0 AWG main power or ground cable into three 4 AWG output connections to feed multiple amplifiers or accessories.
  • High-Conductivity Brass Core: Solid brass block design maximizes current flow while minimizing electrical resistance and voltage drop.
  • Corrosion-Resistant Nickel Plating: Premium nickel finish prevents oxidation, corrosion, and wear in demanding vehicle electrical environments.
  • Protective Insulated Cover: Snap-on, high-impact plastic casing insulates live connections to prevent accidental short circuits.
  • Vibration-Proof Hex Terminals: Oversized recessed wire entry ports equipped with heavy-duty hex set-screws ensure a tight, reliable cable connection.
  • Input Port: 1x 1/0 AWG (Gauge) Input
  • Output Ports: 3x 4 AWG (Gauge) Outputs
  • Internal Material: Solid Brass Block with Corrosion-Resistant Nickel Plating
  • Enclosure Material: High-Impact Heat-Resistant Plastic Cover
  • Terminal Type: Hex Allen Head Set-Screws

Aftermarket tank that actually fits

Perfect fit
Junk man, 2025-12-25 on Amazon


Definitely the way to go fits in the corner perfectly an isn't all bulky like most

Exactly what I needed an it looks like very good quality. Plz the company reached out to me just to make sure I was happy with the product an then offer any help I may need that's super awesome customer service

Great and solid construction!

Used this distribution block to supply power to my engine and all electronic components in my car as the battery was moved to the trunk. Well built and solid construction. I recommend this product!

Excellent buy

Nothing to dislike, liked how the fitting for the wires in were solid and won't pull out, found this out cuz my sub slid on a turn and this actually did not pull come loose.

Great Quality

I received this 1way to 3way distribution block vary quickly, doesn't feel cheap at all, has some weight to it, over all very pleased and surprised with it, I will buy again in future!
COLBY S., 2019-04-20 on Amazon


Highly Recommended

This distribution block is very well built, and has a generous amount of internal space. I mention this because I am running Knukonceptz 1/0 awg in and 4 awg out power wire, and although it is the thickest 1/0 and 4 awg wire I've used, it fits easily without having to do the twist and push method. I would definitely recommend this block

Durable

Works with 0 and 4 gauge...would recommend

Perfect!!!

They are excellent for the setup that I have!
Gordon, 2018-08-08 on Amazon


Exactly what I needed

I purchased two of these: One for ground; one for power. They are solid, easy to open and close and mountable (2 screw holes, screws not included). They were exactly what I was looking for to run 0ga lead to dual amps that utilize 4ga input. Do NOT install these without the plastic cover attached as they are SOLID METAL.
Adam W., 2015-08-11 on Amazon


Easy hookup

I only used two of the 4GA connections right now, so I just tightened down the setscrew on the extra terminal. I hope it doesn't eventually work its way out. The plastic cover doesn't feel like it will stay solidly in place over time. It might be worth adding a zip tie around it to make sure it doesn't open up.
