Ok I have a question. I have a 1000w amp it puts out 500rms @ 2 ohms. If I have a DVC 12" what does the RMS rating have to be? My thoughts were 500 rms but is that per a voice coil or could I run a 12 that is say less wattage since the 500w rms will be split basicly 250 rms per a side. I started thinking about thise since I'm not looking to spend a butt load of money but I do want to buy something that wont blow with in the first month of having it.

I'm confused on what your asking, I'm guessing your looking for the RMS @ a certain Ohm for a sub to match your amp?

yes but would'nt the 500w be divided over two voice coils which would have me needing a sub that is at least 250w rms per voice coil? How are DVC subs rated is it per coil or both coils combined

i dont any of what ur talking about but if u have a 1000w amp and 2 500w subs then u can hook them up to even out the watts.

lets slow down here. the rms rating on the sub is a rating for both voicecoils. you power both voice coils with the same input power. you do not power them individually. a 500wrms sub with dual 4ohm voice coils would need a [email protected]

ok the amp puts out 500w @ 2 ohms. I want a Dual Voice Coil sub that can handle it. My question is are subs rated per a voice coil or both voice coils combined. I only want one sub I don't want two single voice coil subs I don't have the room nor the want for two. I would really like just a 10" sub that can handle that DVC of course. Is that clearer?

Is the amp a mono block amp or a 2 channel amp?

A speaker's power rating (in general) tells you how much A.C. power can be dissipated in the speaker's voice coil without damaging the speaker.

Honest Power Ratings:
The most honest way to rate a speaker is to give the rating as continuous RMS watts (ex: 150 watts continuous rms power). You may hear speakers advertised as "150 watt 6 x 9s" or "100 watt 6 x 9s" and you may instantly think that the "150 watt 6 x 9s" are better and will play louder than the speakers rated at 100 watts. The first thing you should realize is that speaker ratings are OFTEN exaggerated. Then you should ask if the rating is in RMS or peak watts and are the speaker ratings for instantaneous or continuous power. Most car audio speakers (with the exception of some subwoofers) are rated in peak power or music power. Only a few speakers (generally the higher quality speakers) are rated in RMS watts. While peak power is a legitimate way to rate speakers (as long as the manufacturer tells you that the power rating is in peak watts), it can be deceptive.

Peak vs RMS:
You know that peak power is 2*RMS power. If a speaker is actually capable of handling 150 watts of peak power it would only be rated to handle 75 watts RMS. If a speaker is rated to handle 150 watts 'music power', it may mean that the speaker will take only very short bursts of power approaching 150 watts RMS. Even if there are two speakers from different manufacturers which have the same power ratings, one of the manufacturers may be more conservative in their ratings than the other manufacturer. The more conservatively rated speaker would be more likely to handle its rated power. Bottom line, beware of power ratings on speakers. Knowing that some manufacturers are less than honest in their power ratings, will likely help you to make better decisions when buying speakers.

Amplifiers and Speakers:
Many people ask the question... Can my speakers handle this amplifier or will this amplifier blow my speakers. Well, the truth is that any speaker can be driven by any amplifier. The only time that there will be a problem is when the person operating the system becomes abusive. Most people (and I do mean most) drive their amplifiers well into clipping. I know what your thinking... I never drive my amp into clipping. Well, you must be one of the very few. Generally speaking, if you have friends who are impressed by high volume, you drive your system into clipping.

Clipping:
Unless you listen to your system from a distance, you cannot hear clipping distortion until it reaches extreme levels. I know you are thinking that you can probably hear even .5% distortion levels in music. Well, if you were listening to a test tone in an anechoic chamber at an 80 dB SPL on your best day, MAYBE. But... due to the design of the human ear, you cannot hear minimal distortion levels at higher SPLs. At any SPL above approximately 90 dB, your ears overload and cannot accurately convert the sound pressure to the electrical impulses which are sent to your brain. Since most amplifiers are capable of producing more than one watt of power and most speakers will produce at least 88 dB of sound pressure at one watt of input at one meter, it is very difficult to hear minimal distortion at 10, 20, 50 or more watts. If you honestly want to see if you're driving your system into clipping, play some familiar music at the highest volume that you would play it (when you are showing off for your friends) and step way away from you vehicle (with the doors open of course). You may have to turn off your bass amplifiers to listen for distortion in your 'highs'. I think you will be surprised at the levels of distortion that you hear. Now, be honest if you do this little experiment.

Bottom Line:
No one can tell you if you will blow your speakers with a given amplifier. They may be able to tell you whether or not a pair of speakers will be able to handle a given amount of continuous RMS power. But... since they don't know your listening habits or your ability to hear (or even be concerned about) distortion, they (in my opinion) cannot actually tell you if a given amplifier (with you at the volume control) will blow your speakers

mono it puts out 310w rms @ 4ohm but like I said I want DVC and 2 ohm load
Then use a dvc sub with 4ohm coils wired in parallel. If your amp has a subsonic filter & you cut the top off with a active crossover with a 18db per octive slope you can increase the RMS rating to about 350 per coil.
