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????

i was just saying, since he is always saying theyre DVC subs. two of these subs, then wired in parallel to the monoblock, would be perfect. This would then put out 456W RMS into the subs, leaving the amp plenty of headroom, since the subs only need 250W RMS (most daily listening will only be maybe 110-150W).

you cant use the 2 channel amp now, since the 2 channel is only 4 ohm stable in bridged mode. Also, to run subs, its always better to run them off a subwoofer dedicated monoblock amp, they are typically stable to lower impedances.

Your saying it backwards. In bridged mode the amp is only stable to 4ohms. Each channel is stable down to 2ohm which is to say that it can handle from 2ohms and up. Why would you run that amp in bridged mode anyway? He'll get cleaner sound if he uses one channel for each speaker. I did the same thing with my 8" subs in the door. Seperation isn't so important if these are going to be in the trunk but it is an option. All the amps mentioned have low pass filters and the lowest that any of them will go is 32Hz. That mono amps is nice but it is more than he needs and $200 more than he needs to spend. I can think of lots of things to spend $200 on. The real problem with the 2 channel amp is that it will only put out 97W RMS.

Your right about calling them DVC. Urbandork: those subs are SVC, stop calling them DVC.

SVC= single voice coil
DVC= dual voice coil
