JL Audio XD-FDBU-2 2-Way Fused Distribution Block
JL Audio XD-FDBU-2 2-Way Fused Distribution Block — Product description
Adding a second amp to your boat or truck? The JL Audio XD-FDBU-2 splits one power feed into two fused outputs, so you run one wire from the battery instead of two. Blade-style fuses, a snap-on protection cover, and JL's marine-tough build. Clean, safe, and easy to service.
The JL Audio XD-FDBU-2 is a 2-way fused distribution block, and it does one job well. It takes a single power feed off your battery and splits it cleanly to two amplifiers, with a fuse protecting each leg. If you're adding a second amp to a boat or a vehicle and you don't want to run two separate wires all the way back to the battery, this is the part that makes the install tidy.
Here's the setup it's built for. You run one heavier power wire from the battery up to the block, and from there you feed two amps off the two protected outputs. Each output gets its own blade-style fuse, so if one amp shorts or pulls too much, that fuse pops and the other amp keeps playing. Blade fuses are the easy kind to live with, too. You can grab a replacement at any auto parts store.
The protection cover is the detail we like. It snaps over the fuses and terminals so you're not leaving live connections exposed in a bilge, an amp rack, or under a seat. On a boat especially, keeping bare 12-volt terminals covered matters, both for safety and for keeping spray and grit off the contacts.
This is JL Audio's XD series, their bread and butter for clean system wiring. JL builds this stuff for real marine duty, with durable materials that hold up to the damp and the vibration you get out on the water. It's just as at home in a car or truck install, but if you've ever fought corrosion on a cheap block in a bilge, you'll appreciate the difference.
One thing to know before you order. This is the distribution block itself with its cover. Fuses are chosen to match your amps' current draw, so pick the blade fuse ratings that fit your gear. If you're not sure what amperage your amps need or what wire gauge to run into the block, give us a shout. We wire these in all the time and we're happy to talk it through.

Frequently asked questions
What does the XD-FDBU-2 actually do?
It takes one power wire from your battery and splits it into two outputs, each with its own fuse. That way you can run two amplifiers off a single main power run instead of pulling two separate wires all the way back to the battery.
What kind of fuses does it use?
Blade-style fuses, the flat plug-in kind. They're easy to source at any auto parts store, and you pick the amperage to match each amplifier's current draw.
Does it come with a cover?
Yes. A protection cover is included. It snaps over the fuses and terminals so you're not leaving live 12-volt connections exposed in a bilge or under a seat.
Is it okay to use on a boat?
That's what JL Audio built it for. The XD series uses durable materials made to hold up to marine duty, the damp and vibration you deal with on the water. It works just as well in a car or truck.
How many amplifiers can I run off it?
Two. It has two fused outputs, so it's set up for a two-amp system, one output per amp.
Are the fuses included?
Plan on choosing your own fuses to match your amps. The right amperage depends on the current your amplifiers draw and the wire gauge you're running, so pick blade fuses that fit your setup. If you're not sure, we can help.
