Rms is a method of measuring power (wattage) delivered from an amp to a speaker. In almost every case, wattage capacity of speakers is quoted PER SPEAKER. Likewise wattage output is quoted per amp output channel. Assuming a you plan on a single speaker on each output channel of your amp, you should be in good shape if your speaker wattage capacity equals or exceeds your amp's output rating. I've never seen speakers rated as wattage per pair.

(rms is the dominant way of measuring average watts of an ac sine wave signal)

Hi,I have two 250w speakers at 8ohms ,could someone tell me if I need to get a amp with higher watts than the speakers?k


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!

What is the speaker load impedence of the speakers


Looks like you can use minimum 2 ohms, max 16 ohms

LFC Impedance Sensing

CS Series amplifiers feature innovative circuitry for safe operation into any load. When an amplifier senses a load that

overstresses the output stage, the Load Fault Correction circuit adjusts the channel gain to a safe level. Extreme load

fault under high power levels will cause the signal to be muted for the associated channel. This method of outputstage

protection is far more effective than the standard limiting found on conventional power amplifiers. The LFC
circuit is sonically transparent in normal use and unobtrusive when activated.

KENWOOD KR-V8030 SPECS


I have had this exact Receiver and this is taken right from the specs. in the manual, "120 watts per channel RMS" at 8 ohms - this is in Stereo mode (2 speakers) only". When surround sound is used, "75 watts RMS for Front and Center speakers and 15 watts RMS for rear (surround) speakers. From experience, the Stereo only mode is definitely stronger/louder than when switching to Surround. Most newer receivers are the same wattage regardless of mode.

I have a sound stream xta 600.2 what would be the best 12" subs to with it


match your total rms output at the resistance you will be running the amp at to the subs.
example:
if your amp puts out 300w RMS@ 4ohms, then it will produce 600w RMS@ 2ohms. half the resistance, double the power.
So now that you know your available power, you should get speakers that will be used to the fullest at that given resistance.
example:
If you have two 4 ohm subs that have a power handling of 300 watts, Then you can wire them in parallel ( + to + and - to -) to get a 2 ohm load (which will be 300w per sub with the above amp) or in series (+ to - to + to -) to get an 8 ohm load. (300w amp @ 4ohms = 150w amp @8ohms = 75 per sub).

Keep in mind: choose the speakers to fit the amp, not the amp to fit the speakers. If the amp has more power than the speakers can handle, you will blow them. and ALWAYS USE RMS WATTAGES.

Hi i got two speakers clarion xw 1500 ,i`m looking for amplifier good quality and strong enought can supply power for two subwoofer speakers same time,please help me tomargos3@op.pl


The Clarion sub woofers that you have are 600 WATT RMS each, with a combined power handeling of 1200 WATT RMS. Your best option is buying a 1 ch Amplifier (monoblock) Anything in the region of 1000 to 1500 RMS will be more than enough. Brands that you should look at MTX, Phoenix Gold, Soundstream, MA Audio, Kicker, Hifonics, MB Quartz these are but few of the good quality brands out there in the mid to high end range.
If you are on a tight budget then a good alterrnative without a lot of compromise on quality versus cost then Quantum Audio, Crunch Audio, Kenwood will still do the job just fine.

If you are not restricted by budget. Zapco, Mcintosh, DLS and others are up there in the creme de la creme of car audio.
Another brand name that i have used that is not very well know (as far as i know) is Elemental Designs. They have a great monoblock amplifier that delivers all its power at 12V as oposed to most other brands needing 13.8V (V=Volts) and over, it is also suprisingly inexpensive for its quality.

I hope this helps you in the right direction.

No degradation. The smaller the ohm, the better the signal ( least resistance ). You and your system should be fine.
