JL 500.1 anyone ever had one bench tested?

I've heard so many stories on how much power these put out...I know they're rated at 500 watts RMS, but I was just wondering if anyone actually had/seen one bench tested?

Probably the closest your going to come: http://www.carsound.com/reviews/amps/jl_5001.html

The dealers around me tell me they put out 1000wrms at 1ohm, but you know how some like to lie a little bit

thats bull shit. that amp wont produce nearly that power at 1 ohm. if you bench one you will find that it will produce more power at 4 ohms than it will at 2 or 1.5. they will back off on power output to avoid overheating so they can operate at lower ohms without shutting off.

and by the way, i was running two of them and i felt they were a little weak. nowhere near the output i am getting with a zapco 1100.1 dc.

They roll back power regardless of load when the protection circuit detects an overheat. The bench test in the link above would indicate that a blanket statement that they make less power into lower impedances is false.

run that amp hard for a few minutes at 2 ohms and you can hear a difference when it heats up and backs the power output off. bottom line, run JL's at 4 ohms.

Thats why I said "But they like to lie a little bit".//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

its all marketing.

whats it called again when it is able to produce this amount of power from 4-1.5 ohms?

regulated power supply.

whats it called again when it reduces power slightly to avoid shutting off but yet claiming with will produce the same amount.

umm, that would be stretching the truth to sell product. i had two of these amps, i know from experience.

look above you.....could it not be from the heat?//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif//content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

it is from the heat. the amp will run at 2 ohms, but it will make more heat and reduce power to avoid shutting off.

regulated power supply.

Regulated power supply means it can output it's rated power with varying input voltages.

Regulated outputs, such as the Slash series and PG Xenons have, regulate the output so that it outputs relatively the same power into varying impedances.

So I guess the answer is no...except for the link provided.

Can I go somewhere to get mine bench-tested? I just want to know exactly how much power I'm dealing with (whether 500 or 650) when I choose another sub to go along with it.

 

[squeak9798 5,000+ posts]

The difference between 500w and 650w isn't really large enough to make a difference either way.

wow...so nobody really seems to be answering the original question...hmm
