Re: Wiring main speakers

No solder needed. just use regular speaker wire. Recommend 14 or 16 gauge.

How to hook up the subwoffer

There are several methods, depending on the the types of 1)inputs on the subwoofer and 2) outputs on the amplifier (aka receiver). You can only use the type that is on BOTH.

Most sub woofers have "line level" inputs (they are the RCA phono style jacks or other style jack) that are marked "In" or "Input" and may have speaker level input & output terminal that accept speaker wires.

Amplifiers or "amp" all have speaker level outputs and many also have jacks that are labeled "Subwoofer" or "LFE" (low frequency effects) Output. If both your sub and amp have the "line level" jacks, then all you need to do is get a cable that is long enough to connect the two together, and then enable the low frequencies to be sent to the sub instead of the normal speakers in the receiver's set up menu. Done!

If you have only a speaker level connections common to both the sub and amp, you'll most likely need to disconnect the Main front L and R speakers from the amp and connect to the sub's Speaker Output terminals - and connect a couple of new speaker cables between the sub's Speaker Input terminals and the amp's Main front L and R terminals.

If you don't understand completely, provide the make and model of the amp and the sub, and I'll be able to clear up anything that isn't clear.

No sound on anything on the onkyo 626

It will shut down if you have the speaker wires touching, or the wrong polarity of your connected speakers. Check the wiring and connect one speaker at a time. (turn off to connect)

Technics stereo

These units are known for having bad solder connections develop over time. Would have to check bottom of main board for bad connections especially around amp ic's and voltage regulators.

I cant remember how to hook up the speakers to the system

Speakers use a cable that consist of 2 insulated wires. The two wires are identified by one or more ways: 1) one wire may be golden colored and the other white or silver colored, 2) the insulation on one of the wires may have a raised ridge, or 3) the insulation on one wire may have some marking along the surface where the other will not

The terminals on speakers and terminals for the speakers on the amplifier will both have a (-) and (+) symbol for each cable (one for each wire). I like to assign the (+) terminal to the golden colored wire or the insulation with the rib or marking on it, and the (-) terminal to the white or silver colored wire or on the smooth or unmarked insulation. It does not matter which wire you assign to which terminal - as long as the (+) and (-) terminals of the speaker connects to the (+) and (-) terminals on the speakers of the amplifier (you should see to it that they do not get crossed so that the (+) of the speaker is connected to (-) terminal for the speakers on the amplifier).

Connect each speaker location to the corresponding speaker terminal on the amplifier (the front right speaker to connect to the front right speaker terminals on the amplifier - continue until all speakers are connected). Failure to connect correctly will make fading front to back and balance left and right work unexpectedly.

I hope this helps and good luck! Please rate my reply. Thank you.

Hello! I just hooked this receiver up after some time sitting in the closet and it works for less than a minute and then the sound switches to the TV and PROTECTOR flashes across the Reciever screen? I...

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

Fuzzy sound from right front speaker output

The main issue is to determine where the distortion is coming from. Does it start in the front and and get amplified or does it appear in the output section only? This will require a fixed signal and an oscilloscope to trace. Check for leaky coupling caps or leaky transistors in at the diff-amp section.

Pioneer VSX-815 speaker wiring

You can hook them up either way, the banana jacks are good for hooking two speakers to one terminal (ie one through the botton, one banana) but the electrical connection is the same either way. Sometimes the banana capable jacks are on speakers A and speakers B, and the surround don't accept banana plugs, your stuck with how your reciever is wired.

I have to connect 11 speakers in a restaurant to a 2 zone amplifier that is 500 watts per Chanel. How do I choose the power of the speakers and Which way do I wire them --- in parallel?

what size speakers and what watts, how many channels on the amp, you could do it in either way
There are two ways to wire electrical components. In parallel or in series. Both are important to understand, especially when properly hooking up speakers to amplifiers.
Parallel wiring is connecting components to a source so that they share the same voltage. To put that in a useful way, it would be connecting all of the speaker positive terminals to the positive terminal of the amplifier and connecting all of the speaker negative terminals to the negative terminal of the amplifier.
Series wiring is connecting components to a source so that they share the same current. To put that in a useful way, it would be connecting the amplifier's positive terminal to the positive terminal of the first speaker and then connecting the negative terminal of the first speaker to the positive terminal of the second speaker and so on. The final speaker in the chain will have it's negative terminal connected to the negative terminal of the amplifier. Hope it Works

Wiring speaker down to lowest ohm

Wiring a single speaker won't change Ohms.

More than one is a different story.

Parallel wiring is what you're looking for:

Say you have two speakers and one speaker wire.
The positive speaker wire is connected to the positive terminal of each speaker. The same for the negative.

Wiring speakers 'Parallel' will lower the overall impedance according to the following formula:


Say your speakers are 4 Ohms.

Then the formula would be:

1/Rtot=1/4 + 1/4

1/Rtot=1/2 (or .5) Now isolate Rtot


Rtot = 2 (Try it on a calculator)

So two 4 ohm speakers in parallel reduces the impedance to two Ohms.

If you found this useful, please take a sec and rate this response.

Have fun,
