Question

Hello —

My wife and I just bought a condo. It is «pre wired» for in-ceiling speakers in all the rooms (only four!). There are at present plastic caps over the holes in the ceiling where speakers could go. There is a kind of outlet low on the wall in one room with a cover where all the wires come to, so I’m told.

What do we do with this «pre wired» stuff? Do we just by some little speakers, stick them in the ceiling, then connect them to a receiver at that outlet? We really only want to have radio and MP3 player hooked up.

Thnx for any help/advice/knowledge.

Answer

Hi,

Generally most homes now days will have a room or two with the speaker wires ran in the walls for the back channels of a surround sound system.

It sounds like [no pun] this is and install for ‘whole house audio»

I am not in the high tech audio business, but I am sure most of this pre-wired stuff is custom to the builder.

I know some people like to impress with music on and from room to room you hear the same song or whatever.

Think of it, you can irritate yourself in October with Christmas music you can’t get away from, without driving to a Shopping Mall.

You have to put a positive spin on this.

If all the wires end up in one location and there is no way to do a surround system in one room, you have options.

If there is indeed only one location for the speaker ends, I hope they identified them.

If not, it will be a small pain but doable.

You will need an amplifier tuned to a station or a cd playing of mp3, with the volume low, it is ok to one take a cheap light weight speaker and identify the individual speaker connections, you can then mark them positive or negative, either wire, just stay with the same convention through out.

IE: one room has two sets of two wires. When the speaker plays, obviously switching from each pair to the next, mark the one with the white identifier as «positive right room A»

From there you mark each wire and keep your polarities the same.

For the rooms you wish to leave the music out of, you can put a grill over the area, or mud it an forget it.

You could go to the trouble of marking the area on a map, IE 2 feet from west wall, three feet from south, room A

Then mud it up and forget it, put the map in a plastic bag and put in the home files with the electrical diagram or whatever stays with the house/condo.

You didn’t say if it is new, but there may be instructions there somewhere.

It may be a little time consuming but I bet there will be some hints when you find the main feed area.

Speaker wires usually have a mark down one for the polarity, so trial and error till you are done.

Or if you don’t want any of them cover them with a grill or mud up and use floor speakers.

It is just a way to hide wires. Many amplifiers have a/b/c/d outputs so you can be as creative as you want OR NOT.

The caps are locators and if they do not look horrible to you, you can leave them as they are.

There is no electrical hazard or anything to worry with.

Another thought is that if you would like to have hard wired connected smoke or CO detectors the speaker wire may be large enough to do that.

Or an intercom system.

If you do search on the Internet you will find whole house entertainment and lots of options and components.

Maybe you will find you want your radio playing in all the rooms.

Really good sounding either in wall, ceiling, or otherwise speakers are inexpensive, so you can wire up a pretty decent system for not a whole lot of money.

But if you just want to put your player with speaker outputs in one room just do that one.

What you will need if you go multi room is a remote with RF signal [not expensive either]. RF will go through walls so you can put the main unit where the wires terminate and control the device from any room.

IR or infrared will NOT go through walls, you need a direct line of site to control it remotely.

When you find the ends and if it is a big mess, with no instructions, let me know, and I will walk you through identifying and connecting them.

So look around at the possibilities and maybe it will be something you really enjoy.

If not there is nothing you HAVE to do.
