IDmax power Q

[dmcfirestar500 10+ year member]

Hey guys I got a dual 2 ohm idmax 12 and I'm running it in a 1.5 cu ft sealed box. Amp wise right now I have a hifonics brutus 1500D. Right now I'm running it at 4 ohms giving about 500wrms (acording to the box specs, never had it benched to see its tru power). Anyway would it be ok to run that sub at 1 ohm with that amp I know its rated for 1500wrms, but do those amps truly push that much power? Or would you suggest I get a new amp.

Thanks,

Pat

If the amp is 1 ohm stable, why not?

cause the max is only rated at 1000watts rms

So set the gains on the Hifonics to get you in that range. Just because an amp does a certain amount of power doesn't mean you need to be sending that to the driver all the time.

Ok, well my gains are set according to JL's tutorial right now, I will have to reset the gains if I switch over to a 1 ohm load. In doing this how shoul I tune it to not get the full power? What I did is just take the sqrt of the resistance times the wrms to get a voltage of about 38.73, so should I still tune it the same way or should I set the gains lower than that.

Sorry if I seem like a newb, but this is only the second system I've installed and done all the work on so I guess I am.

yea the idmax should have no issues with 1kw in a small sealed box.

would it be safe to put a orion 1200d to it ? or can it handle around 1300 rms ?

Why would you bother?

I've ran 1300 Wrms a peice to several IDMAXs, you should have no problems except maybe on the low notes. If you know the limits of your driver and have some common sense, you should be fine running lots of power. If it starts distorting, turn the gain down a tad and don't play it loud as hell for long periods of time...its as simple as that.

Thanks for all the speedy help everyone, looks like I'll soon be running the Max at 1 ohm

anyone know a place cheaper than 329$ for a 12" ?

i have an idmax and never give it near 1000 watts with music... not even 800 watts.. unless im just trying to show off how much noise it can make. love the idMAX.

one of my boys has a directed 1100d on each of his IDmax's (hes got 3 of them) and they bottom out on some songs (he says its just not enough power) //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

what are some other causes of bottomin out?

to small of a box

playin lower notes then your box is tuned

Too much power. That is the only cause.

Even when playing frequencies well below the tuning of a ported enclosure, the only reason the driver can bottom out because of too much power for the situation. Send the sub little power, and you can play well below the tuning of a ported enclosure.

It's all about the amount of power, plain and simple.
