How do I hook up two p3 4 ohm subs to a 2 ohm


You would hook that up by connecting positive to positive and negative to negative. Then connecting those connections to the matching connections of the amp channel you are using depending if you are using a mono or dual channel amp. Keep in mind that if you are trying to hook this up in bridged mode. It cuts your ohms by half, meaning it will be running at 1ohm. My recommendation would be to run both speakers in series. Positive to negative going to one speaker to the other creating an 8ohm so when you bridge the amp, that's if you are. You'll be running at 4ohms giving you a better cleaner sound 1ef8df95-a777-45c2-94f3-f560ae3fd5ef.jpg

What is the actual watts per channel @ 8-ohms and 4-ohms on the Behringer PMP3000?


Those specs would be right - I have this same board but the amp was fried by a previous owner. I pulled the amp board out and tossed it and use the mixer now to drive an external amp. Great board. This amp is rated at 1200W "peak", bridged into an 8ohm load. That would equate to about 900W RMS bridged into 8ohm or 450 per side into 4ohm loads per side. You can't daisy chain all 4 speakers....impedance would be too low. You can run two of your 8ohm speakers per side - that results in a 4ohm load per side for the amp. That would give you amp delivery of 450W per side. Your speakers are rated to handle more than that so you're fine. For the record.....you could run one speaker per side no problem....just lower power output.

I have a guitar head stack with 2 8Ohm outputs and a 2x12 orange ppc212 slant with 16Ohm impendance. How to link by 8Ohm the two parts?


As long as the impedance of the speakers do NOT go below the rating of the amp you can connect them without worry Your amp would drive two 8 ohm speakers. Using the 16 ohm speaker it will only draw half the current and only accept half the power that one of the 8 ohm outputs can deliver.

CROWN CE1000- slips into fault immediately after connection


if ur output power amp is defective u will have that problem - meaning the moment u connect load across it it will go into circuit protection to limit/stop excessive output current. make sure the speaker terminals are connected to +/- output terminals. in bridge mode use only channel 1 and that too with 4 ohms speaker only otherwise amp will clip. considering all connections are okay if it still clips when speaker is connected, u have a faulty power amp section. this the way ur amp is designed

XR 8600 what color wire on the output connects


Peavey XR 8600?? Well it's 600w per ch. at 4 ohms/per side. So, whichever mode you use (Main, or Main/Monitor) you are best to have a 4 ohm total load for each channel of amplification. Ex.--Mains only, one 4ohm speaker per channel will give you 600W per side. Or two 8ohm speakers per channel in parallel, which makes a 4 ohm total load.

Main/Monitor mode---treat it the same way. one 4ohm, or two 8 ohms parallel. per channel.

Your best situation is to have a 4 ohm total load for each channel of amplification to get your 600W.

Parallel-- 8ohms each / 2 speakers = 4 ohm

two 8 ohm speakers in parallel is 4 ohms.
if series 16 ohms.a high resistance will just produce less power.
too low a number can activate the speaker protect,or blow the amp.
radio shack sell wall mounted speaker controls,but 5 watt max.
the best thing is to run 2 amplifiers.one for in ,2 for out
speaker a and b on the amp parallel the speakers.
if you run 2 sets of 4ohm speakers,the amplifier load will be 2 ohms,and overheat the amp.4 8 ohm speakers,gives a 4 ohm load

Help on 1 amp and 1 alpine srw-124d


You have dual 4-ohm coils. 2 coils per speaker.using one speaker, if you take and run the postive from one coil and connect it to the negative of the other coil, then take a wire from your bridge channel on your amp and connect the positive to the the remaining positive on the one coil and connect the negative to the remaining negative on the other coil you will create a 8ohm load on the amp in bridged mode.

now this is the important part. The bigger the load on the amp the greater the wattage output to the speakers. This sucks the wattage out of the amp. Careful not to overload you amp. The setup above is safe for any amp. The following is for 2ohm stable amps only. The lower the ohm value 2, 4, 8 and so on, the greater the load on the amp.

connect the positive of one coil to the positive of the other. connect the negative of one coil to the other negative of the other coil. then take a wire from your bridge channel on your amp and connect the positive to the the positive on one coil and connect the negative to the negative on the same coil and you will create a 2ohm load on the amp in bridged mode.

Series = add the two ohm value
parallel= halve the ohm value

you can play with series and parallel together using more than one speaker setup.

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....

Connecting speakers


I have never heard of this brand of amplifier.. but NEVER hook up unequal ohm loads to a amplifier. the only way i could think to do it would be to hook up 1 of each sub on each side... what way you are spreading out the ohm load equally on both sides but again if you dont do your math and you run too low of a ohm load you WILL smoke that amp..
