This Home Theatre unit comes with speaker cables that are too short for my intended installation. They appear to be aluminum cables and have a proprietary plug to attach them to the back of the unit. I would like to replace them with longer speaker cables but have two problems. 1.) Will using copper wiring change the electrical characteristics (impedance? resistance?) in a way that will negatively impact the signal quality? 2.) Does anyone have a source for the plugs that are attached to the cables? These might be a proprietary design.

Re: Speaker cables are too short
Just go to Radio Shack and buy some RCA jacks, the length of wire that you need and a soldering iron. Those inexpensive extension cords (12 and 15 foot) at the dollar store make good speaker wire, as copper is better. Just cut off the ends. Speaker wire from an electronics store is expensive.
If you decide to go to Radio Shack or similar store, the clerk should be able to explain everything to you, if not, run, don't walk to another store. You will eventually find someone to help you. If you don't know how to solder, just go to google and type in "how to solder". I'm sure you'll get plenty of hits.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Turn off your unit at the power button. Check speaker outputs for a short circuit - also check other end of speaker cables for a short. If you can't find an obvious problem then disconnect all speakers and power up the unit. If all is OK then connect speakers one at a time (this should be done with the unit powered OFF) and power up after each conection. This should identify which output is causing the problem.
If that does not work then it's an internal fault that will require a service engineer to identify - but I hope that is not the case!
The message appears when there's a short at the amplifiers. Disconnect all the speaker cables and try again:
- if the message is gone then one of the speakers is shorted ; connect them one at a time till the message comes back - junk that speaker and get another one. - if the message is still there then one of the amplifiers has failed - take to unit to a repair shop, that amplifier must be replaced.
Sounds like a speaker wire is shorting against either another speaker wire or something metallic. Check your speaker wires to make sure they're not shorting (touching). If that doesn't work, I'd take it to a repair facility. Good luck!
Uhmmm. . .okay. . .I would use nothing less than 16AWG speaker cable. Do not run the speaker cable parallel in close proximity to any AC wiring. Speaker cable rated to run through walls with usually be color coded red and black. Connected the red to the red on the speaker and red on your home theatre receiver. Do the same for the black. If speaker cable insulation is clear, look closely for subtle markings or writing on the insulation. The writing will only be on one of the two wires. Designate that as the POS or PLUS or + or RED. Connected it to the red on the speaker and the red on the back of your home theatre receiver. The other is by default the black and connect it to like colors. Repeat for all 5, or 7 speakers in your theatre. Your subwoofer probably has a seperate amplifier, so it gets it's power from it's own AC power plug. . .so plug it in. The sound coming from the Home Theatre receiver will be low-power and will carry on an RCA cable. Look for the subwoofer output on the home theatre and connect it to the input on the subwoofer. There may be a right and a left input on the woofer. . .it doesn't matter which you plug it into. . .either one will do.
Home Theater System Is Displaying "Protection"
As soon as the unit is turned on, the word "PROTECTION" will flash on the front panel of the unit and SHUT OFF. This error message usually indicates that the fan in the back of the unit is not on.
The PROTECTION feature automatically shuts down the unit to avoid further damage. The unit will need service if this error message is displayed.

check the cable 1st. If this speaker is powered, you could have a bad shield, or the power is causing a ground loop.
If the speaker is coming from an amp using speaker wire ie: 2 lead + - check the connection and make sure no fraid strands are touching each other on the rear connection.
In addition check your TV, Ap, And speaker system (if sub is powered independently) are all on the same curcuit.
a certain cause for ground looping resulting in hum.
