9/10 on the WTF meter, speaker problem.

[WoogieBoogie 10+ year member]

I am totally baffled at my new issue as it doesn't follow the rules of logic. Ok here's my situation...

- Alpine MRF-P550 (90x4 RMS @ 4ohms) is getting plenty of juice from 4-ga wire and a Kinetics Power Cell not 4 feet away from it.

- Infinity Kappa Perfect 6.1 (6.5"s) components running of front left and right channels.

- If I turn the volume up past like 20% on my HU, the amp cuts out, the sub amp and stock rear speakers that run off the HU continue to play, if I turn it back down, the fronts turn back on.

NOW THE WEIRD PART...

- If I switch the speaker wire to amp connections (hook the driver's side components to the R channel and the passenger side components to the L channel) I have no issue and this is how I have it currently until I find the gremlin.

So ONLY the passenger side components have an issue with the Front-Right channel on the amp, they can be hooked up to any of the other 3 channels no problem. BUT when I hook up the driver's side comps or even a small woofer i had laying around to the Front-Right channel on the amp, they don't have an issue. So it's like okay, the Amp isn't the problem, and the speakers aren't the problem. WTF? Is this some sort of I-D 10 T problem? //content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif:verymad://content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

faulty amp...?

faulty amp...?

That was a thought, but what explains the other set of components (Same exact model) from working on that channel?? It's like the FR Channel and that exact woofer/tweeter don't get along

probably a pinched wire or a short in the line causing it to cut off at higher volumes.

But then why doesnt it affect it when I switch the L/R channels and reverse them?

Well, it's either the speakers or the amp, but not both. Test it again and pay attention to how the passenger comp wires work on the other channels. Intermitent shorts are a pain in the *** to isolate, but very common, look for cuts and kinks in the wiring and connections.

Try to isolate what you know works well, and repeat a problem to confirm which is the bad component.

Ohm meter your passenger comp's to make sure it reads the same as the left side.

I guess Im not the only one who has the same problem. Was looking for a thread like this. I also have an infinity kappa perfect 6.1 set and the same problem goes with other Perfect owners; the amp cuts at high volume. I have an amp perfectly level matched and the same problem presist. I hope soon there would be a solution to this problem. I love my sets but if this problem persist I guess i have to let these go.
