strapping

[Doug McCambridge 4]

With two D1 ohm subs if wired in series for a 4 ohm load with two 1500rms 1ohm mono amps strapped would that give me a final load on the amps of 2ohms being there strapped?

If wired in series/parallel for a 1 ohm load with two 1500rms 1ohm mono amps strapped would that give me a final load on the amps of .5ohm strapped?

Also out of all the researching I've done regarding strapping, is it true that 2 strapped 1500rms 1ohm mono amps be like a 3k 2ohm amp? I posted this elsewhere also n I believe they answered wrong considering everything I find its double the power/ohm just wanna get another opinion in a better worded post

Strapping two amps.

 

 

 

You must run a two or four ohm load to the strapped amps because below 2 they wont be stable.

Your power will double at 2 ohms. You can't go lower then 2 ohms.

You would need 2 D2 subs to get a final two ohm load.

With a strapped pair of amps, each amplifier effectively "sees" half of the load.  If you wire the subs in series-series for a final 4ohm load, then your final load is 4ohm.  No changing that.  Now, since the amplifiers are strapped each amplifier will "see" half of the 4ohm load.  So each amplifier will effectively be operating at 2ohm, and will output power accordingly. 

 

If the amplifiers are 1500w @ 1ohm each, then they are probably around 750w @ 2ohm.  So you would have a total of 1500w of power since each amplifier would be operating at 2ohm and outputting 750w, which is a combined 1500w.

From above, each amp would effectively "see" .5ohm but the actual load is 1ohm.

If you had two 1500w @ 1ohm amplifier strapped into a 2ohm load then yes, the total power would be 3kw.
