Amplifier and efficiency questions

Recommended Posts

So looking for some info about amplifier and efficiency. 

 

I have a xcon dual 1ohm 10"  so i can run at either .5ohm or 2ohm What i would like to know is  1500w @ .5ohm or 1500w @ 2ohm the 2ohm amplifier would be drawing more power to make its wattage because of the higher resistance correct ?

No point in running at 0.5 ohms.

X2...@ 2ohms would be more efficient unless i am missing something..

im currently running a 1000.1d amp at .5 ohm so probably pushing 1300 or so. So your telling me if i get an amp that will push lets say 1300 @ 2ohm its going to draw less current ?  

 

2 ohm load would be higher resistance in my understanding require more current to produce same wattage hence the reason my amp that draws x amount of current can only produce 400watts at 4ohm vs  1300 at .5  

 

Im assuming im overlooking something and just trying to get a better understanding as to what because at 4ohm i had no issues with electrical but now that im at .5 i had to do some upgrades. shouldn't that amp have the same power consumption? obviously not but why.

The amp becomes less efficient the lower you wire down.

The amp becomes less efficient the lower you wire down.

so you arent getting 1300 watts or so as you assume, wiring below 1 ohms causes wasted heat and kills amps components quicker.

      Getting two hds212s and wanna know what amp to get(sq brand) , and if i should get dual 2 ohm or dual 4 ohm. And if youve done this build, what are the box measures

      Crescendo BC3500D is approximately six months old, has never been exposed to low voltage and has no scratches, dings or dents whatsoever. Does 3,875 watts RMS at 13.8v
       
      Xs power XP3000 battery is sitting at over 12.7v after being out of my car for several weeks now and is rated to support 3,000 watts rms power
       
      2/0 welding wire is rated to support over 400 continuous amps of current and has already been heat-shrinked and fused for both positive and negative runs from front to back plus the big three upgrade and an additional trunk ground if you so wish to use it
