W7... Need i say more

[DDDD 10+ year member]

The 500/1 was enough for my 10w7 sealed, and if my new ported box is much louder it will be pretty unbearable (to my ears anyway.)

if you blow your eardrums out with a w7 and 500 watts... you have your ear in the port. thats the only way i could see it happening.

hey, it's their install...if they're not concerned about dB's and competition, let them be happy //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

i honestly hope they are completely content with it. its nice equipment. i just dont think any eardrums will be blown //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

yea dude run some more power to it if u can im running my 10w6v2 off of a 500/1 but then again i did tear my surround due to exeding its xmax(gatta love JL's warranty)

//content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif ....playing tones well below tuning frequency?

I don't know about destroying eardrums, but when I put the 10" in the ported box it definitely hurt my ears pretty badly at certain frequencies.

The 500/1 can theoretically push more than 500 watts as well. I'm just not sure that it actually does because I have no way of testing. But if it can put 500 watts into 4 ohms it can put more into 3 and 1.5 respectively. Since it is capable of producing enough voltage (~44 vRMS) it could technically push 645 watts into a 3 ohm load if it can maintain a stable voltage at that given power rating. I'm not completely sure on just how strict it is on detecting the impedance of the speaker and how well it adjusts accordingly so I could be completely wrong.

Also I don't think my car is capable of handling much more than the 500/1 (90 amp alt). My headlights dim pretty badly on loud notes. Possibly under 12 volts but I don't have a DMM to test it. I'll get one from work tonight and test to make sure I don't blow my alt anytime soon.

yea ssf was off and gains were 3/4 of the way up i never looked at it i just let the guy install it and set the settings...he was new and was fired 2 weeks later

Aren't JL amps regulated and only produce advertised power at all ohm loads?

 

[someone16 10+ year member]

yes dune they are very tightly regulated

 

[DDDD 10+ year member]

Well I just tested how low my voltage drops with the car and headlights ON while playing at almost max volume.

Edit: We did some more tests with the voltage across the battery terminals at given conditions. It doesn't seem to ever drop below 12 no matter what engine RPM nor with the headlights on.

dude no wonder why its so loud to you...you have a wagon...............

if that was in a sedan you would need a two w7's and 1500 watts

Yes, it does 500rms @ 4-1.5 ohms. But like all amps, when you lower the independance and supplly enough voltage - more power will be created.

All i can say they are awsome they are the best sub i have heard so far but i have not heard many others.

completely contradicting yourself? what am i missing?

WTF?

It will do 500rms from 4ohms down to 1.5ohms. That's the min. RMS though. It will actually do more than that.
