Pros: (1) It is fused which means you get extra protection. (2) It has water resistant housing which prevents spill from short circuiting your equipment and, (3) it is small enough to fit anywhere in your vehicle.

Cons: None so far.

I Used this dist. block to power my two subs, one under each front seat, installed it right under the center console and fits perfect. I have my subs powered and protected with one dist. block in addition to the fuse protecting the whole system and a circuit breaker. Great choice if you need efficiency and protection.

t spec and fuse

As always, t spec never let's me down. Good product meant to do its job efficiently

Great Value: Poor Build

I ripped this housing apart easily with just the screws! I would recommend below 4 awh for this distribution block. It still works effectively even though the housing is destroyed but truthfully it is not as "rugged" as I needed it to be.

Perfect for dual amp install

Highly recommend this part.
Takes care of fusing for both amplifiers in an easy to reach spot.
I've bought 2 of these now. Very good fit and finish for the price.

great for modern smaller cars

The whole T-spec line seems to prioritize compactness. The fuse blocks I used seemed well built and look great!
