JL AUDIO w7 DB??

[paintball9908 10+ year member]

I know the w7 is not made to be the loudest woofer, but I have a 10" w7 in an H.O. wedge ported enclosure, a 500/1 jl audio amp, and an alpine cda-9815 hu, what kind of db's should I be looking to get??(system not hooked up yet, waiting for amp)

I am thinging mabey along the lines of 138 or so, anyone have any ideas??

Depends on the mic and mic placement - amung many other variables.

138 doesn't sound too far off if you were just looking for a guesstimate.

its going to be in the back of my 2000 grand am, I am asuming the mic would be placed at the front passanger dash, is that not were they are at comps???

i imagine it will be plenty loud, my friend has that exact set up (amp sub and HU) in his tahoe and its close to 140, and sounds incredible

Probably about 135db's Lin X with only 500watts, you could get up to 137-138's with more power, maybe like 700-800watts which that sub can certainly take. I do like the custom HO ported boxes, the W7's sound REAL nice in em.

another thing on my mind, i dont know if you ave ever watched the w7 video showing the excurtion of it on the jl audio sight, but how many watts would I have to feed it to get lets say 3 inches of excurtion??

considering the one way xmax on a 10w7 is 23mm (.9in), i dont think with any ammount of power you will reach 3 inches of excursion, but with 500 you will be able to reach the w7s full excursion (though not 3 inches //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif )

.9" is one way excurtion, say it goes a little the other, so ya think I could get an inch only with 500watts?

it will reach full excusion witha 500/1 on it
