I'm going to test my orion 2500d.i no its a different amp but this is my point.im going to put 3 dual 3.68 ohm 15s in parallel to get .614 ohm then turn my radio to the highs volume that's clean and instead of turning the amp gain to highs point of clean power in going the lower it so the amp still puts out the 2500 rms maybe even little lower like 2k .turn the radio to max clean power and see if the amp gets warm.if stays cool I'm going to do the same with 2 6ks on 6 15s.3 on each amp.im worried about stressing my amp that's all

You ask for help, and then still do it the way YOU want to. Waste of energy bro...

did you not read anything I put?

Sounds like, you have a amplifier, and .5 is your only option, and you're not sure if it's safe to run in your vehicle. If this is true, my suggestion would be to run at .5, and leave the gain down on the amp.

The gain on the amp, is only to match the level of the signal coming from your radio, so it's not necessarily a volume knob, it's more of having a clean signal from the radio, and for the amp, to receive that same clean signal, without any outsource input between these two points.

I hope this answers your question, and if it doesn't, than let us know!

What I would suggest, is to run it at .4. Turn the radio to full max listening volume, I typically advise 10 to 15 percent below the max number on the radio. Now, go back to the amp at .5, and turn it up until either, your voltage can't hold the load, or the sub is taking too much power. This would invole you having to listen to the sub, and gracefully determine what is the safe zone, depending on your listening style and music type.

Also, please bare mind that, the enclosure will have more input on how the sub takes the power, more than whatever ohm load you decide to run.

So if you have a 15 that is rated at 3k, and you want to put 6k on it. Than a box at 2 cubes prob would handle the power better than if it's a 6 cube box. BUT, just because it takes the power, doesn't mean it's doing it efficiently. Essentially you're suffocated the speaker so that the suspension is tighter, therefore allowing more power to be applied.

In a large box, the enclosure doesn't support the suspension as much, therefore, it could get just as loud with much less power. BUT, if you add too much power in a too large box, then you will have speaker failure.

So it's a lot to know, and there is no right answer to your question.
