I thought it was square root of double the watts times the resistance?

AHHH NM i am too tired to think.....

Here's the formula you'll need ...Sqrt(Power*Resistance) = Voltage

(i.e. If you bridge a 4 ohm subwoofer to your amplifier that is rated to produce 100 RMS @ 4 ohms in bridged mode, you would want Sqrt(4*100) = 20 volts)

thats from jmacs tutorial thread (top of the amp section)

so if we go Sqrt (1000*4) it should be 63.25v i believe (as long as the little java calculator works that im using

my ranger is double cab (this one: http://www.terra.com.br/fotos/foto.cgi/UF0nwfoiz9AKiCuSMoOKU8K9-._djNmqbEIQmW/Ranger02.jpg)so i let the box seating in the rear seat, with the sub facing the windshield. got it? and i need space to 2 persons, at least.

i´ll bench the amp tomorrow, btw, anyone knows how big is the ranger alternator?

Dude, try turn the sub around! //content.invisioncic.com/y282845/emoticons/idea.gif.5acb6a39a9b92425414c316dda202bad.gif

also polarity could be a possibility...although he said its not moving as much as it should so maybe not

Dude if your saying the sub isnt even half way to xmax it cant be the box. Especially that its a sealed box it should have even greater excursion than a ported box. My 15" HC is in a 2 cubic foot sealed box and its sometimes too much for me and the gain is only 1/4 up. I dont think you are having box problems. Just make sure its sealed very very well. I think people sometimes under estimate sealed boxes. I mean, think about it. Even if the sub was playing 3 db less than its full potential at 1000 true watts, that is still some serious power.

thats exactly what i think.

i read somewhere that sealed handles more power and it haves greater excursion.

let me bench my amp and i'll post here my impressions.
