I'm about to buy a Kappa Perfect, I have a 600 rms amp by infinity. If I turn the gains down will I clip the sub? I was told by a installer here at work that the Kappa Perfects are very sensitive. Turning the gains down would still feed the sub 600 rms at a lower voltage. This seems incorrect since the outputting voltage wouldn't equate to the wattage.
So who's right? will i kill the Kappa Perfect if i put it on 600 rms at a lower voltage? I plan to order a 10 inch today through work. Before I do, I want to know can i run my amp on it sealed at 1 cubic foot or so without issue? I have a 98 nissan sentra, i need to keep the build light and box small so suggestions?

As long as you dont hear any sort of distortion and use common sense you should be fine. it is rated 350 rms and is a well made sub. i put 500 each on mine a while ago and was fine, till my dumb brother had em for a few days.....lol but anyways, its not like your putting 1000 to it or anything.

well no but i plan to use a digital multimeter and so fourth with setting my gains. it just sounded wrong when i was told even backing down the gain would still give the sub 600 rms, that's the point of the gain isn't it? to control the volts going out that relates to the rms being put out? GlassWolf if your around can you clarify for me?

the infinity subs are sensitive, which means they put out more sound per watt of input.

I have been reading up GlassWolf and it's all great information. I'm still unsure though, can the Kappa Perfect take it? Boss i apperciate the input , i'm just looking for somene with experience running the perfects. Can anyon give me a honest opinion if they ran the perfect how many Rms is safe to throw at them? keep in mind i only plan on running 1. I have a infinity 600rms amp. Worst case i'll have to buy a alpine 300 rms amp but i really rather use the equpiment i have.

Turn the gain down and it will be fine. It is extremely rare that a speaker is damaged from too much clean power. It would have to be to the point of over-excursion of the cone which you would surely notice.

Great news I did some research since my amps about 2 years old. It's the infinity reference 1600a series amp. It will do 400 rms at 4 ohms which puts me back in buisness since the sub is rated at 350 rms. At 2 ohm the amp does 600. So get the 4 ohm version and I should be golden.
