4 ohms will be a final load of 2 or 8 ohms

2 ohms will be a final load of 1 or 4 ohms

if you get a 4 ohm speaker, look up amp specs of 2 ohm ratings

if you get a 2 ohm speaker, look up amp specs of 1 ohm ratings

Are you unaware that not all speakers have dual voice coils? Or are you just trying to confuse the fvck out of him?

incorrect

a dual 4 ohm subs final impedance is 2 or 8 ohms

a dual 2 ohm subs final impedance is 1 or 4 ohms

to the OG post, most amps put out more power the lower the impedance so you might get more wattage for your buck if you get a dual 2 ohm sub vs a dual 4 ohm sub, or if you get a 2 ohm sub vs a 4 ohm sub etc etc

at 4 ohms an amp operates more efficiently than at lower impedences

Will two subs with dual 2 ohm coils enable you a final of 2 ohms?

If you are trying to get the most out of your amp and it is one ohm stable, get two 4 ohm subs and wire them parallel. Then your amp will run at one ohm and push max power. (And get hot)

i dont think i have ever seen you give correct information in a post, keep trying one day it will happen by accident

The more ohms, the more resistance to electricity. more ohms=less power that your amp will put out.

If you are trying to get the most out of your amp and it is one ohm stable, get two 4 ohm subs and wire them in series. Then your amp will run at one ohm and push max power. (And get hot)

he meant parallel..

 

[mannyahles 10+ year member]

omfg, are you serious? series 4 ohm = 8 ohm...

I meant parallel so I edited my post. Sorry folks! I had a quick moment to answer this post!

Not always.

Some amps are built to be more efficient at lower loads.

But, most of the time, this case is true.

Actually, I aim to run what ever I get at 2 ohms, I know you can run a DVC 4 ohm at 2 ohm when parallel wired, but a few of the subs I find interesting is only 2+2, and I haven't figured out yet how to get these to work with an amp at 2 ohm.

It seems to be easy to run 1 ohm or ohm but getting the correct ohms wired either in parallel or series to achieve 2 ohms is not so easy! Thats why I went my route. Just get an amp that is 1 ohm stable...piece of cake!

This is the sub amo I use and I have had it for 9 months without any problems. Its a great price at $179!
