Overview

Our take on the T-Spec FDB-124M

Distributes power safely and neatly

This compact distribution block from T-Spec will handle the high-current power distribution for your multi-amp sound system, ensuring that your wiring's connected securely, looking neat, and safely fused. The set screws for the fuses have specially-designed heads that accept many common tools, even a coin, so you will always be able to change your fuse without having to carry around a special tool. Solid black nickel-plated brass construction ensures reliable power flow, and an impact-resistant plastic cover keeps the fuses and connections clean. You'll need Allen head wrenches to install this block. (Fuses sold separately.) Warranty: 1 year.

Excellent quality

T-SPEC MANL Fuse Holder

Mitchell from Milwaukee, WI on 5/15/2017

Crutchfield Customer Review (What's this?)

When installing the fuses I may have over-tightened them, but they just still seemed loose. I ended up very slightly bending the fuses, and the small square blocks on the output side of the block actually twisted a little and were touching. And I don't mean that I bent or warped the metal, but it just seems like they're actually designed in a way that they can twist. When that happened I called it quits and decided to look for a different option, I found a Scosche block from a local big discount retail store that takes maxi fueses which just slide into place, no screws needed. Operator error? Maybe, probably; but I really think I could have wiggled the fuses out even before I over-tightened it.

Crutchfield Customer Review (What's this?)

This is an awesome product! I love the fact that it is very compact, but still gets the job done. I don't want to showcase my power distribution stuff, I just want it to work well. The fit and finish is very high quality. Last, but not least, it is only rated to support up to a 4ga wire on the output side but I was easily able to fit a 2ga.

I been buying T-spec products for a few years now. And I have to admit that their equipment is way better than any other competitor. Power, cables, RCA cables, speaker cables etc all under the T-spec brand are the best equipment for your car audio set up.

Great fused distribution block

Connor G. from Colleyville, Texas on 1/19/2015

Crutchfield Customer Review (What's this?)

The distribution block came packaged very nicely and had no troubles figuring out the install!

Pros: Allows you to fuse your system at the distribution block, I had a seperate fuse holder in my system but with this you're able to have different fuse sizes on each side specifically for each amps fuse requirements.

Cons: Was not completely descriptive that it had to have mini anl fuses

Good Product

duel battery setup

Anonymous from maryland on 7/27/2013

Crutchfield Customer Review (What's this?)

The exception of losing one of the fuse mounting screws and having to find the odd metric size replacement locally this product is great. I am using it for a dual battery setup somewhat in Reverse of the planned way (I have this protecting the battery from the isolator on one side and also fused to a large aux fuse block on the other with the large cable going to the aux battery. It works perfect for my uses and the fuses come in the sizes I need to protect my equipment

Pros: price, functionality

Cons: odd metric screw size if you loose one.

Small and perfect
