You can gently tap a nine-volt battery to the side of the wire pair that will be connect to the amplifier. When you've got the loudspeaker connected in proper phase, the speaker will push out, instead of pulling in.

Please send me a diagram of how the wiring is to be set up on the back of the speakers


The red connector on the speaker should be connected to the Pos.(+) connection on the Receiver/Amp. The Black to the Neg. (-) connection. ( for the proper speaker) Front Left, Front Right,etc. All, or most paired wire has either a black stripe,different shape on one,or different colour wire(silver/copper) So if you hook up the Blk striped or silver to the Neg.(black terminal) on the speaker, do so at the other end (receiver ) If both speakers aren't hooked up the same, they will work, but there won't be as much Bass because the speakers will be out of phase.(when one speaker cone is moving out,the other will be moving inward.

I have a klh home theater speakers with a subwoofer the sub work but when i hook up speakers no sound comes out?


The sub works but the speakers don't? Do you hook up the speakers to the subwoofer output "loop"? This is a circuit issue when it works and stops working. I have the same issue so I wound up joining the wires that go to the sub and the wires that go to the speaker together and place those connections into the sub. The sub works, the satellite speaker works and the impedance load is no issue for my system. Confused? Simply run your neg/pos wire to the sub and where it connects to the sub, run another cable to the speaker (pos to pos., neg to neg).

The only way to repair it would be to deal with component level repair. Although I have the experience, it is too petty and it works fine the way it is.

Speaker Err on Yamaha Home Theater Unit ???


I am assuming this is the message that shows up from your receivers front display panel? It could be the receiver is telling you that you may have the neg & pos. wires crossed and in the opposite position either in back of the receiver speaker posts, or in back of the speaker terminals themselves. My Yamaha receiver has this nice feature where it will tell you when the speakers are "Out Of Phase" which describes the problem I have described here.

Just go back and make sure your wires are hooked up correctly, and use tape and a Marker to label pos. and neg so they will be easier to hook up next time you have to move the system, or decide to change some aspect of your system. I would then take the time to label every wire that goes to each speaker that you plug into the back of your receiver. This a BIG time saver........

How do I hook up banana plugs to a infinity PC 350 speaker


The illustration in the manual I found at retrevo.com isn't detailed enough to show the axial connection option, which would normally accept a banana plug inserted straight in if the opening is conductive and about 4mm wide. I suspect it is as they mention a "variety of wire connectors".

Their only illustrated example show bares wire ends inserted into a small hole drilled through the termial post and the red or black plastic piece tightened down to secure it.

WIRING THE SYSTEM
IMPORTANT: Make sure all equipment is turned off before making any connections.
For speaker connections, use a minimum #16-gauge speaker wire with polarity coding.The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +).
NOTE: If desired, consult your local Infinity dealer about speaker wire and connection options.
The speakers have coded terminals that accept a variety of wire connectors. The most common connection is shown in Figure 5.
To ensure proper polarity, connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker, as shown in Figure 6. Connect the – (black) terminals in a similar way.
See the owner’s guides that were included with your amplifier, receiver and television to confirm connection procedures.
IMPORTANT: Do not reverse polarities (i.e., + to – or – to +) when making connections. Doing so will cause poor imaging and diminished bass response.

I have the Yamaha HTR5935 reciever- When I turn the power on, the unit stays on for about 3 seconds and then shuts itself off. So the power is running to the unit. Any ideas?


Sounds to me like you have either your speaker wires crossed, the pos and neg are touching, or a pos is touching the case of the receiver.

How do I install a volume control.


Ok, without actually seeing the back of it, I can't say where your connections go. But, I can tell you that there will be a positive and a negative for both L and R sides And 2 wires that go to your volume control on your amp.(1 for each side) you will be able to combine the 2 wires that go to your amp and it will still control both the right and left on your speaker.

I have had a set of Polk Audio SDA1 speakers that I had attached to an old but great Pioneer SPEC-1 pre-amp and SPEC-2 power amp. The old speakers had one connection for the right speaker positive and...


bi-wiring requires the removal of the copper jumpers between the hi and low speaker terminals. you can use two wire pairs twisted together at amp out connections and the four separate ends at each speaker, but the quality of sound will not be as good as buying quality bi-wire cables. But a pair of quality single set of wires at each speaker would be fine, but put jumpers back on and attach to the top terminals, they are designed that way. bi-wiring does allow the crossover to put out a little better sound. Hooking up four sets of wires to the a and b speaker terminals sounds bad. i have had alot of trouble with my rti10's and learned the hard way that it is best to pay more for wires with quality terminations.

Wiring into walls


Okay, here's the verdict. No such din connector for the Bose AM15's exist. I thought I would take another look to see if anything had changed since I had looked last. Once again, all is the same and it makes using standard wiring a pain. However, it is possible to do what you want to do, which I assume is a nice clean install. I have rigged many of these systems, and, here's what I do.

First, the biggest pain is the 25' LFE cable. Shortening it is a pain because the wires are thin and dificult to splice. Lengthening it isn't a great idea either because you want to keep the cables as short as possible. However, a lesser of 2 evils exist and that is to keep this cable whole. Before you begin, peel the LFE cable from the buch untill it is separated from the bundle. Next, peel the speaker wire for each speaker so the pos and neg for each speaker is together, but, separated from the bundle. Then you'll place the sub where you intend it to go, plug in the 13 pin din (I even looked at vga options...nada) and stretch the cable to the wall and cut one speaker wire at a time (+ and -) being CAREFULL to mark which wire is positive and which is negative after the cut. DO NOT cut the LFE cable, and make sure you give yourself an extra foot or so before you cut the wires.

Once the cuts are complete and you have labeled pos and neg for each wire, you may strip the wire and plug into your regular speaker wire wall plate (banana or clips). On the reverse side of the plate, attatch the pos and neg to the plates making sure everything is consistant. Then, run the wires to your receiver (or vise versa). Regular speaker wires typically distingush pos from neg through some sort of marking on the wire housing.

The other cable you will run is the sub (LFE cable). If you want to just drill a hole in the wall and stuff the cable in and run it to the receiver, that's one way, but if you want to keep it clean, use a single RCA connection wall plate. Then, to minimize loss of LFE sound, run a TV coaxial cable from the sub to the receiver and terminate both ends with RCA terminators.

Once the wires are run to the receiver, double check that all the speakers are hooked into the sub and the wiring is complete. Take a AA battery and mark the location of the speaker that corresponds to the wire. In other words, with the speaker wire, hold one end to one side of the battery and the other end tap lightly to the other side of the battery. You will hear a crackle or pop locating the speaker the wire goes to. Once this is identified, label the wire and plug into the appropriate output making sure the pos and neg are consistant.

A picture is worth a thousand words, so, I drew a diagram and will attach it to this forum asap. Good luck and have a blast!

Instalation instructions required


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.
