I wouldn't hook anything up except what Yamaha recommends to the speaker output terminals. That's pretty much asking for trouble!

I am trying to connect 2 jbl flip 2's to each other. It is not working. I was told by the rep at Best Buy that I could pair two together so I have two speakers playing at once...


Be careful when you do that. The amplifier may not be able to operate when you do. If you take 2 8 ohm speakers, for example, and connect them parallel then you have a 4 ohm load to the amplifier. That may damage the output stage of the amp. Same goes if you series them as then the load would increase to 16 ohms.. The only way you can properly connect 2 sets of speakers is if there are terminals for speaker a and b on the amp and there is a switch on the amp for speaker a /b / both.

How to hook speakers up to a realistic mpa-40


The MPA-40 is a mono public address amp. So it has one speaker output. You select the appropriate socket to suite the speaker type. The 4/8/16 Ohm outs are for various tpyes of Hi-Fi speaker. The 70 Volt is used for muzak in shopping centres, restaurants, and waiting rooms.

If you have a pair of 8 ohm Hi-Fi speakers, you can diasy chain the connections and then use the Com and the 16 Ohm connection.

Daisy chain means you take the wires from a pair of speakers. Connect together the wires going to red on one speaker and black on the other. This now leaves you with two wires going to the other red and black terminals on the speakers, but the ends in your hand are not connected to anything yet. Plug the black in to COM. Plug the red in to 16 Ohm.

The sound from the speakers won't be stereo. It will be mono because that's all the amp outputs. But both speakers will work so long as they're functioning units.

If you have two 4 Ohm home theater speakers then you can do the same trick. 4 + 4 makes an 8 Ohm load. Connect the red to the 8 Ohm output.

Don't be tempted to try to connect to multiple terminals. The amp isn't powerful enough to to run more that one speaker chain.

Hope this helps

I have Boss ar2400 4 channel amplifire.. I had connect two 15" kicker subs in bridge circuit. When i run the system it gets overheat in half an hour and goes into the protection mode. How can i solve this...


Problem is one of four things:
  • Impedance (ohm resistance) of the speakers you are using is below the amplifier's rating for operating in bridge mode;
  • You are driving the speakers at a volume exceeding the maximum power output of the amplifier;
  • The gauge of the wires you are using to connect the amplifier to the speakers is too small;
  • The gauge of the power supply wires is too small, and/or you are not using a large enough reserve capacitor at the power input
Possible solutions:
  1. If your Kicker subs are rated at 4 Ohms, and you are using them in monoblock configuration with the speakers wired in parallel (all + terminals to the + bridge output and all - terminals to the - bridge output), try either configuring your bridge circuit in a paired bridge, where a pair of amplifier outputs are bridged, each bridged pair driving a single speaker; or if your Kicker subs are rated at 2 Ohms, use a monoblock bridge driving the speakers in series (+ bridge output to + of one speaker, - of that speaker connected to the + of the other speaker, and = of that speaker connected to - of the bridge output);
  2. Turn the amplifier output down (but this is likely NOT the issue)
  3. Use speaker wire that is no smaller than 8 gauge for your application. 4 or 2 gauge wire would be slightly better but not worth the additional expense;
  4. Your power supply wire should be equal in size or larger than your speaker connector wire. Use no smaller than 8 gauge for your application. Also, use a capacitor no smaller than 2 Farads wired across the power supply input to the amplifier to compensate for pulse surges and car power dips. For your application a large capacitor will work better than an auxiliary battery or gel cell.

I Have a Peavey XR 600B mixer. There are only 2 inputs in the rear for speakers. I want to add more speakers to be used as monitors or just have extra speakers. How can this be done? I only have...


First off it's outputs to your speakers. If you had an extra set of powered or amplified speakers you could "Y" cable your speaker outputs. Your passive speakers won't work without an amp. You really need powered speakers or an amp for your extra speakers. (if you had powered/amp'd speakers you could run them off one of you "aux" out for monitors. Do not daisy chain your speakers connecting twi together, you'll change the resistance/ohms and damage your speakers. Trust me, I do this for a living.

How to run wires is series fof 3 subs


If they are single voice coil speakers (1 positive and 1 negative terminal on each speaker) then connect from amps' Positive output terminal to spkr. 1 positive terminal, THEN spkr. 1 neg. terminal to spkr. 2 positive terminal, THEN spkr. 2 negative terminal to spkr. 3 positive terminal, THEN spkr. 3 negative terminal to amps' negative output terminal.

That is 3 speakers wired in series. if each spkr is 2ohms, then you will have a total 6 ohm load. If 4 ohm spkrs., then a total 12 ohm load, if 8 ohm spkr., then a total 24 ohm load.

Be careful because amps do not like these odd ohm load totals. You might get away with a 6 ohm total load. Depends on the amp.

Hi monmax,
I hope you are aware that in bridged mode your amp will become monaural (single channel, double power). If you still wish to bridge it:
Switch of power.
Set mode switch behind amp to "bridge" position.
Connect speaker positive to CH1+ve terminal of amp output and connect speaker negative to CH2 +ve terminal.
Be aware that now, in bridged mode your amps output power delivery is 1100 watts for a 4 ohm speaker and 900 watts for an 8 ohm speaker. Make sure your speaker can handle that.
Peace
Jango.

Wiring woofers


Well, you have the 4 ohm dvc kickers, and your amp being stable to 2 ohms doesn't go together very well. If you wire the voice coils in series, and hook the speakers to the amp in parallel, you get 4 ohms, which doesn't use all the power your amp is capable of. If you run the voice coils and the speakers in parallel, you'll drop the resistance to 1 ohm, and probably fry the amp, or at least deal with overheating issues. Better be safe than sorry. You need to run each speaker in series, which means running a positive and negative to each speaker, and a jumper from those terminals to the opposite colored terminals on the second voice coil. Diagram can be seen here: http://www.kicker.com/06/tech-support/manuals/manuals/02SoloBaricL7manual.pdf That puts two 4ohm voice coils in series, and raises the resistance of each speaker to 8 ohms. Then, you have to run both speakers in parallel to the amp. When you run two 8 ohm circuits in parallel, the total resistance of the circuit is 4 ohms. That means seperate positive and negative wires to each speaker. If it is a mono amp, connect both negatives to the negative output, both positives to the positive output. If it is a multi-channel bridgeable amp, You'll probably connect the negatives to one side output (right for example) then connect the positives to the opposite side output (left for example). If you need to bridge your amp, make sure it is bridgeable, and also that you have the speakers bridged to the proper amp outputs. If not sure, reply back here with the amp model number, and maybe I can help you further.Thanks, and I hope this solves your problem.

Behringer ep2500 amplifier


Yes you can,,,,,BUT the output labelling on the AMP will tell you where you can connect the 4ohms or the 8ohms....please read these labels and connect the 4ohm speakers to the 4ohm terminals, and the 8ohms to the 8ohms terminals...

If you intend to connect the 4ohm and the 8ohm speakers in parallel then the output impedance terminals you use should be the 4ohm ones.

If there is no labelling showing any 4ohm output terminals then its best if you dont use the 4ohm speakers at all....just connect the 8ohm to the 8ohm terminals...you dont mention any crossover networks inside the speaker boxes or if you have tweeter speakers... so just stick to the basics above at present....
