Wiring Options

Wiring Basics

You will need a wire that has at least two conductors; one that can be identified as the positive and the other as the negative. All two conductor wires have some means of identifying which conductor is which, but at times this identification may be subtle. It’s crucial that you keep track of which wire you use for positive (+) and negative (-). Typically if the wires are colored red and black, the red wire is used for positive and the black wire is used for negative, but sometimes other colors or patterns are used. You can choose whichever color of wire you want to be positive and negative as long as you remain consistent throughout the install.

On both your amplifier and your speaker the connectors will be identified as red for positive and black for negative. It is very important to look carefully at the speaker wires and be certain that the same wire that is attached to the positive connector in the amplifier is attached to the positive connector in the speaker.

Installing the Wire

Strip ¼ to ½ inches (6 to 12 mm) of the insulation off both ends of the wire. To avoid stray strands, twist them at the end. Connect the wire to the amplifier, and make sure the wire connected to the left speaker output will be routed to the left speaker, right output to right speaker, etc.

Wire Routing

Plan how you’ll route the wire to the desired speaker location. There are several methods for routing the wire, and you may need to combine several of them.

Behind the Baseboard

The wire can be routed behind the baseboard by cutting a groove out of the back of the baseboard, or by buying special baseboard designed for concealing wires.

Through Walls

When running wires through a wall, be sure to avoid all obstacles such as AC wiring, pipes, and ducts.

Attic or Basement

When available, you can route the wire through an attic or crawlspace.

Under the Carpet

One option is to lift up the carpet and rout “tape wire” under the carpet.

New Construction

If these speakers are being installed in a new home during construction, the installation process will be a bit different (although much simpler). For these situations, it’s recommended you purchase a bracket. Instructions on how to install the speakers are provided with the bracket, or can be found on our website. Visit for more information.

A1250 Features

Clean Amplification

Our amplifiers utilize modern digital technology packed into a small chassis. True to all of our amplifiers, they are neutral in coloration and provide high quality sound for all applications.

Protected Zones

Each zone (A1250) is protected in isolation with an operational LED indicator on the front panel. This way, problems can be quickly identified visually. If a problem is found within a zone, the other individual channels will continue to play, even as the trouble zone is off.

Global and Local Inputs

Each zone can be assigned to one of two global inputs (Analog and Digital) or individual local inputs. The output gain is individually controlled for the zone with a single knob. This control stays consistent regardless of the input selected. This setting is typically the final control for your gain staging, so ensure you set the volume at a level that will not introduce distortion or clipping.

Secure Connections

Each zone features a secure Phoenix-style connector that accommodates up to 14 gauge speaker wire.

Rack Ready

This amplifier features rack ears and feet for flexibility in the installation method. It only requires 1U of rack space, with the proper gaps for cooling between amplifiers.

SUBA150/A500 Features

Clean Amplification

Our amplifiers utilize modern digital technology packed into a small chassis. True to all of our amplifiers, they are neutral in coloration and provide high quality sound for all applications.

Line/LFE Inputs with Loop Out

Connect to another amplifier or receiver and loop out for even more flexibility in planning.

12v Triggers

These amplifiers are turned on out of standby mode either by sensing the audio signal from a preamp or receiver or by a 12-volt signal from any number of components. They also have a 12-volt output to trigger other components as necessary.

Rack Ready

This amplifier features rack ears and feet for flexibility in the installation method. It only requires 1U of rack space, with the proper gaps for cooling between amplifiers.


If you have a problem, try isolating it first. For example, if you’re playing a DVD and there is no sound, try replacing the DVD with an MP3 player to see if you get sound. If it does work, then the problem is with the television, DVD player, or the cables connecting them. If it doesn’t work, the problem will be with the amplifier, speakers, or those cables.

Common Solutions

NO SOUND The volume may be turned down or muted. Check the volume settings volume may be turned down or muted. Check the volume settings on both the amplifier and the DVD player/ television/ computer/ etc.
NO SOUNDMake sure the proper source is selected on the amplifier or receiver.
NO SOUNDCheck the cord connecting the amplifier with the source. The cord may be damaged or plugged into the wrong input or output.
NO SOUNDCheck the wires connecting the amplifier with the speakers. Make sure they’re connected properly and not damaged in any way.
POOR SOUND QUALITYIf you hear something like static, or the sound is cutting in and out, check the audio cables. If the problem increases when a cable is being moved, then the cable is most likely faulty or not connected properly.
POOR SOUND QUALITYToday’s audio systems may have several places to adjust the volume, for example your MP3 player may have a volume control, and your amplifier may also have one. Check to be certain that the volume isn’t turned up past 80% on any device.
POOR SOUND QUALITYTry changing sources to be certain that the selection you’ve chosen is a good quality recording.
