I think you'll be fine.

Yeah, so you think the Infinity Kappa Perfect will still sound good with around 40wrms??? I like my music nice (sq) and loud btw. ;)

I checked my manual, and I dont know where it says that.

by Robert Wollenberg » Sat May 13, 2006 4:40 am

so what? you'd have to jump to 80 wrms to get a 3 db gain over the 40 wrms. Is 3 db going to be worth what you'll have to pay for a new amp? I doubt it.

I check the manual for the kx550.3, and it states 2 x40 wrms @ 13.8v.

So I dunno now.

It will do fine on that. Perfects don't really get loud anyhow.

I'd stick with what you got.

Well...that amp puts out 40 rms at 12.5 volts. Thats your battery voltage when the car is off. Once your car is running it will be around 13.8-14.4.

SO, they would receive more like 60-70 watts. They should be fine w. that.

So you think just over 40wrms will be fine for my Infinity Kappa Perfect (100wrms)????

by Robert Wollenberg » Fri May 12, 2006 8:33 am

The difference between 40 wrms and 60 wrms is roughly 2 db.

Also, I'm pretty sure headroom isn't associated with how many watts an amp produces. An amp either has it or not and you either chose to use it or not by setting your gains properly.
