Our take on the T-Spec DB-1144

Distributes power securely and neatly

T-Spec designed this DB-1144 distribution block to handle the high-current power distribution for up to four amplifiers, while keeping your wiring connected securely and looking neat.  You can also use this hefty little block to combine the ground wires of up to four amps to a single grounding point. Solid black nickel-plated brass construction ensures reliable power flow, and an impact-resistant plastic cover protects your connections from the weather. You'll need Allen head wrenches to install this block.  Warranty: 1 year.  

Works great easy to install

I needed 4 each 4 AWG inputs and one 1/0 output. I have used this product before and have had good results. [ William  Jul 03, 2017 ]

needed a power block with no fuse this seemed like a good quality part. [ Jeremy  Apr 14, 2016 ]
Needed it and what can go wrong with this product? [ Ryan  Mar 11, 2016 ]
I chose a ground distribution block for ease and cleanliness of grounding multiple amps with only one (heavy duty) chassis ground cable. This one will serve three amps and an equalizer. [ Danen  Feb 04, 2016 ]
good solid distribution block [ Austin  Jan 11, 2016 ]

2 questions already asked

You can use 4ga in. It comes with a spacer so you can use 4ga or 1/0ga into the block. [ Gregory  Apr 13, 2017 ]
First off, the single terminal side comes with a ferrule that allows a 4 gauge cable to be connected at the single terminal. If you are using it as a positive side distribution block, the feeder cable (input from the battery) needs to be large enough to carry your total connected load. If you are running four 500W amps off the outfeed side, you should run 0 gauge on the input. If you are running a total connected load in the 800W to 1200W range, 2 gauge should work, and if you are under 600W total connected, 4 gauge should do the trick. Of course, your length of run of feeder wire will also determine the gauge you should use, so check out the charts. Now, if you are using this block as a grounding block, Use the same gauge for your primary ground as you used for your primary feeder to your distribution block on the positive side. Some people don't recommend using a grounding block with a common ground as it allows feedback (noise) in your system. I haven't had any trouble with that as long as all my ground connections are clean. [ Danen  Apr 12, 2017 ]
4 IN AND 4 OUT WILL WORK TO [ JUDD  Apr 12, 2017 ]
I forwarded your question to an Advisor and they responded with the following: You can use either. The connections are secured with set screws, so if you use a 1/0 gauge wire you have to just loosen the screw more to allow for the thicker cable. Then you tighten the screw back on the wire once inserted. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
