sub amp wiring ops. ohm and watt, how does ohms relate with watts? expert needed Options

[urbandork]

Assuming im using dvc subs that have an rms of 250w


what 4ohm load amp would i be looking at wattage wise???? would it be 250 watts RMS x 1 bridged output at 4 ohms. or would it be 500w?


what kind of mono and or 1ohm amp would i be looking at would i need it to be 250 at 1ohm or 500???

I get the sub and stuff but how does wiring of the subs in parallel and series as well as ohm at amp to ohms at subs affect the wattage being put out by the amp.

Last but not least which of these two wiring options should i go with????

since the obvious was never stated
Ohm should be a measurement of resistance, the more resistance in a speaker the better the quality(or so i believe, not 100% on how speakers work)
Watt is just a Joule/second (energy per second) the greated the energy it can handle, the greater the outputs it can have.

The ohms in relation to a speaker is actually called impedance, and that is used amplifier selection purposes. You dont want to run a 4ohm car speaker on an amp in your house that is only stable to 8ohms - you could fry the amp. The resistance in the coil on a speaker will change greatly depending on the frequency being played. Like up to hundreds of ohms of resistance or more IIRC. And speaker quality has nothing to do with speaker impedance. You may have it confused with ohm load on amps, as they tend provide cleaner power at a higher impedance at the sacrifice of power.

The only 'good and bad' with dual and single voice coil subs is wiring options. You decide which you want based on the amp you are getting, how many speakers you are running, and what kind of load you want on the amp. One is not better than the other providing you have all the voice coils hooked up.

We can't decide on an amp for you to get, there are too many options out there. Just an FYI, I have not heard about Infinity amps being anything special, you might want to look around so you can save some money. In other words, you can find a better amp for the money. If you are set on getting (2, two) 4ohm DVC's (the infinitys will be model number 1042w or 1242w, not 1040 or 1240) then find an amp that puts out 500w rms at 4ohms (either 500x1 or 250x2,) or find an amp that puts out 500w rms at 1ohm. Just know that you can spend less on the amp if you get 4ohm SVC's because you can run 2 at 2ohms.

And it's long, but everyone should read this.
