Preface: The instruction set herein is a guide for self termination of speaker cables by means of
crimping. Soldering is not the preferred technique and as such detailed soldering instruction is not
provided. There are several acceptable methods of termination and the instructions herein are not
a specification. Instructions for braided sleeve covering are not included in this set of instructions.
The included instructions are not necessarily the exact methods used for Furez factory
termination.

Notes:
1) Larger heat shrink tubing may be required when more than one conductor is used per connector. Test
your heat shrink tube before assembling with a small piece. Once you crimp you may not be able to
rework the shrink tubing.
2) Heat Shrink tubing sizes listed by most manufacturers are listed as nominal dimensions. Please refer to
the manufacturers actual specifications for internal diameters when selecting heat shrink tubing for your
projects.
Tools Required
- Utility Knife (Blade Only)
- Wire Cutters
- Typical Wire Crimp Tool
- Tape Measure or Ruler
- Heat Gun
- Clean Latex, Vinyl or Cotton Gloves
- Copper & Silver Dry Cleaning Wipes
Dry cleaning wipes and gloves are usually supplied with the speaker cable connectors.
Note: Cable strippers are NOT recommended for stranded speaker cables.
Furez Speaker Cable Jacket Removal
Step
Instruction
1
Determine you cable free length. The free cable length is the separation between the
speaker cable connector and the cable jacket. The free cable length should be long
enough to allow for a relaxed connection of components. The free cable length can be
as long as needed and the typical minimum recommendation is 6”.
2
Run the utility knife blade around the cable jacket with light
pressure at the measured point of your free cable length. Do not
cut all the way through the speaker cable jacket. The goal is to
get about half way through the thickness of the jacket. This
ensures the speaker cable conductor insulation is not cut.
3
Bend the speaker cable at the point where it was cut to inspect
the depth of the cut. If done properly the cut will not have
penetrated all the way through the speaker cable jacket. Lightly
cut all the way through the speaker cable jacket while bending
the cable.
4
If your speaker cable jacket does not easily pull off, very lightly
run the razor blade down the length of the cable jacket. Use very
light pressure when making the lengthwise cut to ensure the
underlying conductors are not cut.
5
Using wire cutters snip the end of the speaker cable jacket
where you made your lengthwise cut. This snip will allow you to
easily pull apart the speaker cable jacket without cutting all the
way through the cable jacket.
6
Pull the speaker cable jacket apart along the lengthwise cut. In
most cases the cable jacket will pull apart easily but you may
need to cut the jacket again while doing this to get the cable
jacket off.
7
Remove and cut away any exposed paper binders or fillers in
the speaker cable after removing the cable jacket.
8
Test fit the speaker cables on your equipment to ensure the cables lay with little to no
stress on the conductor ends. Make adjustments to the speaker cable free length as
necessary to ensure minimal stress on the cable, connectors and equipment.
Furez Speaker Cable Conductor Insulation Removal
Step
Instruction
Cable strippers are NOT recommended for stranded speaker cables.
The use of gloves while handing bare copper is recommended.
The suggested strip length for a single conductor in a W series crimp style connector is 5/8”.
The suggested strip length for paired conductors in a W series crimp style connector is 3/4”.
Straighten and lay the conductors out and trim the individual conductors so that they
are equal lengths. The original twisting of the conductors can sometimes leave the
1
individual conductors at different lengths. This step ensures that your individual leads
will be the same length.
2
Run the utility knife blade around the speaker cable conductor
insulation with light pressure at the proper length. Do not cut all
the way through the conductor insulation. This ensures no wire
strands are cut off or damaged during removal of the insulation.
3
Bend the speaker cable conductor to inspect the cut insulation. If
done properly we will have not cut all the way through. The cut in
the insulation will typically break though with bending. If
necessary cut all the way through the speaker cable conductor
insulation while bending the conductor.
4
If your conductor insulation does not easily pull off, press the
razor blade through the insulation along the length of the
conductor insulation. You will want to use enough pressure to go
all the way through the speaker cable conductor insulation. This
should be done with a pressing motion not a sliding motion.
5
Peel off the speaker cable conductor insulation. Remove any
broken copper strands.
Attach Furez W Series Crimp Connectors to the Speaker Cable
Step
Instruction
The use of gloves while handing bare copper and or silver is recommended.
Single Conductor Per Connector -Twist the bare
speaker cable strands to ensure the stranding is
relatively tight.
1
Paired Conductor Per Connector -Twist the bare
speaker cable stranded ends together to ensure the
stranding is relatively tight. Do not twist the conductors
separately before combining.
2
3
Install heat shrink tubing onto the conductor before
proceeding. The heat shrink will provide protection
against oxidation, identification and most important for
this style connector - strain relief. Two layers of heat
shrink tubing or dual wall heat shrink tubing can be
used for increased strain relief. If using two layers of
heat shrink make the bottom heat shrink tube slightly
shorter than the top heat shrink tube.
Test fit the stripped conductor.
A proper test fit will result in the insulation stopping at
connector entry and the wire strands should bottom out
in the connector bore.
Trim the wire strands and or conductor insulation as
necessary to ensure proper fit.
Position the speaker connector in the crimp tool as
shown with the dimpled side of the tool positioned on
the bottom of the connector and the half round side of
the tool on the top of the connector.
4
Crimp once just before the open window in on the
bottom of the connector as shown.
Then crimp once at the beginning of the connector just
before the open window on the top of the connector.
Both crimps dimpled side on the bottom of connector.
5
6
The resulting crimps should look as shown and be
positioned as shown. Note the top looks round still and
the bottom has two distinct crimps. Neither crimp is
placed over the soldering windows. One crimp is before
the first soldering window on the top and the other
crimp is before the soldering window on the bottom.
If you want to solder you can now use the soldering windows provided for
soldering. Furez Products only solders upon request.

The use of gloves while handing bare copper and or silver is recommended.
The crimp connection is now a permanent connection
so you can take added measures to protect your cable
against oxidation by applying some 100% silicone calk
to the open areas of the connector and at the entry of
the connector. Let the silicone dry before applying heat
shrink. The silicone will not cure with heat and requires
air to cure.
Slide the heat shrink up to the flange on the speaker
connector. The flange is intentionally there to serve as a
stop for the heat shrink tubing. If you have two pieces of
heat shrink, do them one at a time.
Shrink the tubing using a heat shrink gun intended for
heat shrink tubing. If you do not have a heat shrink gun
you can get by with a hair dryer but the hair dryer will
take longer as it does not get as hot as a heat shrink
gun. Let the cables rest and cool so the heat shrink
hardens before handling.
Clean the connectors with a dry copper / silver jewelry cleaning wipe. Note:
Adding a drop of lemon juice to the wipe will aid in cleaning copper but is not
necessary for silver.
