JL 1000/1 and Kicker L7

RE: JL 1000/1 and Kicker L7

no sir. do you realize what clipping does to voice coils at high volumes? to be brief, it makes it move top to bottom very sharply instead of smoothly. it can be hard to detect, especially with subwoofers, and even harder in a bandpass box. look at the waveform of a clipped signal, and take a look at how sharply the voice-coil makes transitions upwards and downwards. At high volumes it has to go even farther faster. It's not opinion; it's science. Physics don't lie.

I know what a clipped signal looks like, it's a square wave. And yes it's real easy to blow subs in a bandpass box, because it's super hard to hear distortion in those type boxes.

THe RMS rating of a sub is measured as the limit of it's thermal abilites (mechanical limits are 90% box size). How well the sub dissapates heat is part of what makes it a good sub (among several other attributes) 600 clipped watts to a quality 1000 watt sub is still below it's thermal handling limits. the sub will definalty sound like crap, and will probably be nice and warm, but that's about it.


Here's a couple links that explain it further. The first one is from the god of car audio info sites, and includes this handy qoute...

"If your speakers are capable of handling significantly more than your amplifier can produce, driving them with a clipped signal will not likely hurt them.
If the speakers can handle 3 or 4 times the power that your amplifier can produce, there's virtually no way to damage your speakers (no matter how clipped the signal is). "

The link is, http://www.eatel.net/~amptech/elecdisc/2ltlpwr.htm

also here is a LONG thread (16 pages) on another forum about a guy trying to argue that too little power kills speakers. It gets so crazy that Tracy Focht from kicker, and Dan wiggons, creater of the XbL2 technology, and founder of Adire audio, has to jump in.

As wacky said (god I wish everyone knew this, and I'll paraphrase) As long as your smart with the gains, everything will be ok.

Hope this helps!

My buddy has a pair of Rockford HE2 12" in a bandpass box running parallell into a 600 watt amp (2 ohm). I keep fixing it and within a week hes complaining it sounds like crap. He turns the damn Gain to max, the 45hz bass boost to max, and the crossover to 250hz. He wonders why he can only hear bass, and after he turns his deck past vol level 4 that it sounds crappy. It gets old telling him to not touch the amp. His amp does have a nice smell comming from it now though :)

Yeah, and its a crappy Jensen KA-3 3 channel amp, that I can't believe still works.
