Infinity Kappa Perfect 6.1

My friend and I have been having trouble with these components sending his amp into over current. He has a 4ch Alpine(75x4) He has other amps and it has done the samething to them as well. We ran the perfects direct and it had no problem but when you run them with the crossover it sends the amp into OC. If anyone can think of something that could be going wrong that I couldn't think of it would be great. It is only at higher volumes and it is deffinitly not the amp because we wired other speakers up to it and it worked flawlessly.  Thanks for any input.

You may have arcing in the crossover. One of the chokes may have arcing from some of the windings exposed somewhere in the core. It may also be one of the caps drying out or going bad or a cold solder joint.

I run mine with a mere 50x2, so its not the wattage. Do you get any sound at all out before the amp hits protect, or does it shut down as soon as the XO is connected? -daveThis is not a sig. This is a duck. Quack.

It plays fine at lower level volumes but once you turn it up it always goes into overcurrent. For example the max volumes before it goes into protect you could have a conversation over the music, which in my opinion isn't very loud. i know the potental of these speakers but I have never had this problem. They are currently witrah an alpine 75x4 I can't think of the model number but it is sit at 4volts and if you turn it any lower than that is when it starts going into protect mode.
