Speakers are rated either at RMS (root mean square) average power or Peak Power. An RMS of about 125 watt is equivalent to 250 watt peak. To match the radio and speakers they both need to be consistent. Also do not be confused with total radio power out vs per channel.
So if the speakers are 250 watt peak power then a radio with 125 watt per channel or 250 watt peak per channel would be a good match.
If the speakers are RMS 250 watt then the radio would be 250 RMS/channel and usually with a four channel radio a total of 1000W RMS
With that much power the neighbors should hear you coming!
Look for a 4-channel amp that pushes 50 watts RMS @ 4 ohm.
Make sure the amp is CEA-2006 compliant.
Ignore peak or max watts as these are arbitrary numbers.
Is that the RX113, or some other? The 1500 is informative, being peak power total. This is about 375 Watts/channel RMS, which is enough to blast the neighbours anytme.
Most likely cause is heat. The clearances behind the radio are often not sufficient to provde the proper air coolling that the higher power radios need. The heat sinks on the rear of the radio require a certain amount of air flow to dissipate the heat generated under high load conditions. If you add summer heat to the equation, you can have the radio going into thermal cutout to protect it circuity.
Hi, As long as you like the way the speakers sound there is really no reason you cant use whatever speakers you want. To find out the approximate wattage of the stereo you are using look on the rear of the unit and you will find a tag that has " SPECIFICATIONS " on it. There you will see perhaps the a.m. and f.m. frequencies it's capable of receiving also there should be numbers saying something like" 100-240vac or 100-240v~ 50-60hz 1.2amp or 120watts.( if power is listed in amps only-1 amp's equivalent to about a hundred watts)Dividing the wattage by 3 will give you an approximate power out put. Example if your stereo draws 120 watts worth of 110 from the wall it will put out approximately 40 watts to each speaker. Changing from OEM speakers is all right as long as you don't try to hook up some 150 watt peak speaker to a stereo capable of just, say, 10 watts per channel. Doing this will eventually cause damage to the amplifier, not to mention causing about 30 percent total harmonic distortion-which take my word for you will know if you ever hear it! So long story short-use what you wish, just be careful not to overload the receiver-if the speakers are a bit to powerful for receiver you can lessen distortion by turning down the " BASS" as that takes the most power in a speaker. Thanks for choosing FixYa, I hope this helped-good luck, Prodzilla
I have a pair of these. Best audio thing I ever did. One amp as the the crossover is built into the amp. If you can find the compatible dual 18s then you'd need a second amp. Recently read a spec that they drop to 20 hz at 10 volts. So when you turn up the volume they rock with the bass truly showing a peak of their capability. These are just amazing. I originally used a crown xri4000. Just bought a Nad T 877 HT and when run only in stereo with QObuz, pretty incredible. Not the final purpose of this amp though. I may use the line outs to integrate the Crown Amps. Still getting an idea. So One powerful amp. You won't blow these out.
Amps can be rated based on their RMS power or their peak power. In this case, the amp's rated RMS power is 300x2 at 2 ohms (total 600W RMS) with a peak power rating of 600x2 (1200W peak). For the most part, peak power means almost nothing.
If your head unit didn't have RCA preamp outputs, you would used the standard speaker outputs from the head unit and connect them to the hi input plug of the amp.
Hi this is Compaqowner again NOTE: I know enough about home Stereos,and I am pretty sure to figure out 'power output' you take the total:in this case it takes in 110 watts total devide that by 2 so according to my math that is 55 watts (I guess this AKAI has a 55 watt amplifier) then you take the amplifier output (in his case 55 watts) and devide that by how many channels are being used,so in 5.1 DOLBY mode DVD movie,etc.(power to all 5 speakers) then it's 11 watts per channel,and in 2.1 stereo (power to the subwoofer,front right,and front left speakers only) it jumps up to a little over 18 watts per channel,again,I think?,when you find the answer,please let me know. Thank you for your time. Steve B.
