ohms to amp?

OK i just finished builiding my box holding to ten inch audiobahn dual voice coils 300 watt rms subs that runa at 4 ohms but i am adding a third sub to my console in my dodge ram and was wondering could i run my two subs at 4 ohms on a 2 ohm stable amp thanks adam

are they DVC cuz if their not there gonna be running at 4ohms stereo which your amp has to run at as well

if you run all your speakers in series you would have 16ohms of resistance if you run the speakers in parallel you will end up with 1ohm which wont work with your amp, providing that both coils on your subs are 4ohm coils which isnt always the case but if they are IMO the most efficient way to wire them is coil to coil in parallel and sub to sub in series or vice versa. this would give you a total of 4ohms

If everything seems to be going well, you have obviously overlooked something.

You can always use a higher ohm load on an amp.  The stability rating refers to the lowest load that can be accepted.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

thank you all or the help

wait if my amp is 2 ohm stable when i start running my 3 subs at 2.6 ohm will it be pulling more juice since its closer to 2?

You have three DVC 4 ohm speakers, right?  In series/parallel you have a 2.67 ohm impedance.  Here's how to figure the amplifier output into the load:

Look at the amp specs for the power output into 2 ohms.  Your 2.67 load will be less power output because its a higher impedance.  Now look at the amp specs into a 4 ohm load.  You know that 2.67 falls between 2 and 4 but not exactly in the middle (3 falls in the middle).  So what you do is find the middle between the two rated outputs (3 ohm load) and your subs will get slightly more power than that.

Is it a stereo amp that you are planning on bridging or a mono amp? Mono, yes, you could get a 2.67 ohm load for tha amp, but in bridged mode, that would be 1.3 ohms - too much of a load for the amplifier.

What amp do you have? If, as I said, it is a stereo amp, it is only 4 ohm stable bridged, 2 ohms stable in STEREO mode...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
