Can it handle this much?

Hello everybody..

Well, I have a Rainbow Hammer 12" Sub, 400 Watts RMS, 750 Max (supposedly). Anyway, I know people have given massive ammounts of power to some of rainbow speakers, and I was wondering if the sub i have could handle...say 1100watts?

this is the amp I was thinking of getting.

Of course, the gains would be set correctly using a DMM ( i ain't gonna go by ear with that much headroom).

Anyway, I just don't really want to have to buy another sub because I accidentally smoked it.

If it can't handle it, I can find another that gives less, but, well, more power is more power.

Oh, and if anyone knows where i can pick up some free test tones (I've looked and the links don't work for me for the ones i find here) that would be great.

Thanks,

Eric

Of course you can use that amp. Just set the gains properly with a DMM like you mentioned. Start at the recommended max RMS and slowly work your way up from there until you get nervous (or it smokes //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif ). Better to have an amp with too much power than not enough...

well, It's D2, so it also shows that 400x2 @2 so i could do either 800 watts or wire it at 1 ohm to be 1100 watts.

Also, what do you mean work my way up from the max RMS? sorry to be nooby...just wanna be careful.

Factory spec'd max RMS = 400W. Set the gain for that and then slowly work your way up. ...405, 410, 420, 450, etc. I definitely wouldn't give it 1000+ watts. In fact, I'd likely be real nervous around 550-700W depending on the install.

so i just use:

sqrt(*x1)

*=by the * i mean this is where i "raise the wattage"

1ohm load.

right?

Correct.

SQRT(400*1) = 20V

SQRT(405*1) = 20.12V

SQRT (500*1) = 22.36V
