Right side speakers don't work

I have a Jenson 40 watt 4 channel amp in my 68 corvette and the amp don't seem to have any power coming out of the right side speaker wires to the front or rear. The left side works perfect. When i plug the right speakers on the left side , they work eliminating bad speakers. Is there any way i can test the amp.? Thanks in advance, Bernie

If you are using RCAs as inputs to your amp.Swap the R to L @ RCAs to see if its comming in okay from radio.If both RCAs have audio then amp is bad ,If amp has any type of switches , move swithces to see if it comes back .Also if both RCAs inputs have audio .Move the RCAs when connected on amp to see if amp has bad connection in board to RCA jacks..If audio comes back on bad side when jack is moves .Then you have bad solder joints on board..If not then you must have bad outputs on amp..

I have a Yamaha H/T receiver rated @ 95 watts. The front and rear speakers a hms and the center channel is 4 ohms. Is this a dangerous setup for my receiver to function in?


You seem to be confusing the power of the Receiver with the impedance. Watts is how much power or how loud it can go. While ohms is the impedance of the device. The receiver will have an lowest ohms setting for it's speakers. For example if it says 4 ohm you can connect any speaker of 4 ohms and above to it. However if it said 8 ohms then you should not connect any speaker lower than that.
Each channel will have it's own power level measured in Watts. Some units have the same level for all channels, others have different levels for the channels. You can connect any speaker that has a wattage greater than the channel's total max power. If you connect say a 50 watt speaker to a 70 watt amp, it will work, but you must never take the volume to even near the max or it will blow the speaker.
Anything with a mono soundtrack will only decode on the left and right channels. Unless the unit has something like an all channels setting. So the unit seems to be working fine. Mono films have no surround effects applied to them, so the indications are simply showing they are working. They of course feed no surround to other channels, as none are present.

Which speakers (Front/Rear) to buy that match Kenwood KAC-M846 4/3/2 Channel Amplifier.


I don,t no where you are reading thease articles from,I installed car audio equipment for over 40 years, Untill i retired a couple of months ago, Who ever is writeing those sort of articles does not have the slightest clue what they are talking about, It is the opposite way around, It is allway better for yor (Speakers) To handle more power then what your amp puts out, Then you will not blow the spaekers, It is best to get speakers at least 20 watts more then what your amps maximuin (RMS) Watts are, Hope this helps you out, (PS) 50 watts (RMS) Is what most people go for, It is in no means (Under) Powered.

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.

How can you bridge a 2 channel 300 watt amp to a 4 channel 300 watt car amp?


if you have (4) 4 ohm speakers (No Subs), then you simply take the (2) positives from the two right speakers, and the (2) negatives together and put them on the right output of the amp. Do the same for the other side. This will have the amp at a 2 ohm stereo load on each side, which will max out the power of the amp. Will sound great with any small power amp.

There is simple no answer to a question like this. It's just an amp. There are no tweaks except volume. What are the speakers and how much undistorted power can THEY handle?

Amps don't 'run' from 'x' to 'y' ohms. The spec you're viewing tells you how it acts with loads at those values so you can plan accordingly. Since they don't mention distortion values with those wattage numbers the power specs are meaningless.

ANY amp driven beyond its 'clean' power limits will start distorting and THAT will kill speakers if not the amp itself. Audible distortion and excessive heat at the amp are signs of stress. The best sound and performance will be somwhere below that point.

http://www.pyleaudio.com/manuals/PDG4000.pdf

It's not clear what is represented in the "XXX Total Watts Power" statements on page 6. I'm guessing that would be what it DRAWS in wall power so you can plan where to plug it in without tripping a beaker.

Hence, given that no amp converts all of its drawn power into audio power since a lot of heat is created, the actual usable audio output wattage would be somewhere closer to maybe 40% of the total divided by how many speakers are driven. No reputable manufacturer specs an amp at 'x watts time y channels'. It's "PER CHANNEL all channels driven" that makes any sense for comparison.

If a car can go 150 miles per hour and has 4 wheels is that 4 x 150 for output if it had only one wheel?

How do you switch the behringer 3000 to bridged mode,what settings do you use to get 1200 watts out of it.


Well... you probably won't like this, but here is some info: In bridged mode, a different Speakon to speaker cable is required from only the B... it is wired differently and you can only use one of the plugs. The speaker or speaker system CANNOT be less than 8 ohms in bridged mode... this precludes using speakers in parallel or multiple speakers that are less than 16 ohm impedance... such speakers are NOT commonly available as most are either 4 or 8 ohm. There is a slide switch for bridged mode on the face of the mixer. Next thing you won't like... The 1200 Watts specification is PEAK power, NOT RMS... You can get 400 watts RMS per side USING 4 ohm speakers. If you use 8 ohm speakers, each of those will get 200 watts. I use this mixer myself and ALSO repair them. The voltage swing at the outputs is about +/-60 volts MAX (peak). This is about 40 volts RMS by the time the circuit LOSSES are taken into account. Across a 4 ohm speaker you get 10 amps times the 40 volts or 400 watts. Across an 8 ohm you get 5 amps or 200 watts. The voltage rails in the switching amp are +/-70 volts DC so these are reasonable values. Bridged mode just uses both sides of the amp driven in opposite directions for higher voltage out BUT you have to use no less than a single 8 ohm speaker so there is NO advantage to bridged mode power wise. IF YOU NEED more power, use extra speakers from an additonal amp driven by the 1/4 TRS mains output jacks OR use additonal POWERED speakers driven from the same jacks. Please read my tip about the hazard regarding the SLEEVE of the cahnnel A cable when using Speakon to 1/4 plug cables being the HOT and the tip being the cold for channel A. Ground the sleeve accidentally and goodbye channel A amp...

What kind of amp do i need for 2 kicker ds6930 140 watts peak and 2 ks6930 6x9 watts peak 150 and 3 Kicker KS350 3-1/2 40 watts each peak


600 Watt to 1000 Watt 4 CHANNEL AMP for the four 6X9's and a less powerfull 4 Channel amp thats at least 200Watts to 400Watts peak for the 3 3-1/2 kicker speakers. Because if you try to connect the 3 3-1/2 speakers to only 1 4 channel amp that the 6X9 speakers are on you risk of overheating the amp and blowing the speakers too!!!

I need speakers for my Onkyo A-911M integrated amp


A+B speakers = 4 channels 2 right 2 left

100 watts/4 = 25 watts per channel

RMS watts / channel = 25 x .707 = 18 watts/channel which is your average consumer stereo system

I would use 8 or 16 ohm speakers (not 4 ohm) -- almost any set of stereo speakers will "work" -- these will be 8 ohm and about 5 watt minimum / 40 watt max thereabouts

I found this amp and I can't seem to figure out what the wattage is?


You are probably aware on how to use these output figures, but I'll write a quick explanation on the specifications for future readers anyways :)

The concpet CC-452 amplifier has the following power output specifications:

Calculated at 14.5 volts DC;

At 4 ohms per channel - 45 watts x 2 (RMS)
At 2 ohms per channel - 70 watts x 2 (RMS)
At 4 ohms bridged - 150 watts x 1 (RMS)


This means that your amplifier would provide 45 watts of power each for your front speakers, which are normally a 4 ohm load per side (45 watts for left, 45 watts for right), that's unless they are one of those exotic higher end brands (eg: Boston Z6s which are 3 ohms). Rarely, you will find speakers that are rated at 2 ohms per side, but in this instance the amplifier will provide 70 watts of power into each speaker. On your speaker specifications, you will find a value termed "nominal impedance" which will give you the ohm rating of the speakers being used..

On the other hand, if you "bridge" both channels into a single channel (using a diagram often marked on the speaker terminals of the amp), you could then provide 150 watts into a subwoofer (providing it was a 4 ohm woofer).

It's not recommended to use this amp bridged under 4 ohms..

Some subwoofers may be lower than 4 ohms, and you will not be able to use this amplifier for these types of speakers without risking amplifier failure. Also, some subwoofers may have 2 seperate voice coils, and you will have to use both channels of the amplifier seperately (not bridged) in order to correctly connect this type of speaker for use.

Hi Trim God,

 

I do not reccommend that you push the Pioneer speakers over 100 watts.  The jenson will already drown the car with bass through your pioneers so much you will want to turn off the bass boost when playing some low bass hip hop songs. It changes from one venue of song to another, so I just keep the jenson bass boost off and use my head unit to adjsut the sound to fit my listening prefences. I am telling you man, you will be blown away .  Hook up the pioneers straight to the Channels,. do not bridge.  I put Subs in my truck though.  I used the Pass output to send the audio to me Jenson 2 Channel 600W amp. I drive one 10 inch enclosed JBL Class A/B Sub. I bridged the output of the 600 W amp to the 10 inch sub  in my Z28.  The pioneers never get drowned out.  I did smoke my 2 channel Amp one time. and also took out a MTD 10inch sub. I am talk shooting flames and smoked the whole car up. I think if you bride the XA4150 to the pioneers, you will have the flaming smoke problem in no time.
