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????

Are the subs 4ohm DVC? I'm assuming so because of the diagram you put it. Do realize that any amp running at a 1ohm load (which most amps are not capable of) will be running very hot and distortion will be considerably higher than a 2 or 4ohm load. Did you already purchase these subs?

If you did not, and you want to run 2 subs, then I would get (2) 4ohm single voice coil subs, wire them parallel, and hook them up to an amp that is stable under a 2ohm load, and puts out around 500rms watts at 2ohms.

Alternatively, you can get (2) 2ohm DVC subs and wire them like this:


If you already purchased the subs, and they are 4ohm DVC, then you can use either of the wiring diagrams you posted. Personally, I would find an amp that puts out 500rms watts at 4ohms and wire the subs up to it like in your first diagram.

Generally, an amp will put out more power (but run hotter and have an increase in distortion levels) the lower the ohm load. However, many amps that are stable down to 1ohm will not have any power increase over 2ohms. If you are not going for an audiophile sound system, try in run the subs at 2ohms, that way you won't have to spend as much on the amp.
