debutis,
What is am saying that the w7 can handle 5000 watts of 20 hertz pink noise played for 12 straight hours. I am not talking a few second burp. but 12 constent hours of 5000 watts. And the pole piece was so hot, water srayed on it instantly evaporated. we are talking several hundred degrees, JL didn't take a tempature tho.
I have also seen CV strokers handle 3000 watts before the tinsile fried.
The amp in question is a Crown 5000 which is a industreal amp used for pa systems, very happy to run at 1/16th of an ohm or less. Practicle application of the Crown 5000 one is used for the entire sound system at the indy 500 track. The Crown amps is not a common amp but would waste most all car amps with out breathing hard.
You are right a bad install can make even the best equipment in the world sound like crap.
