I think it looks kick butt when subwoofers are mounted on the outside of a box so you can see like the voice coil and crud but I have only seen this type of settup on ported boxes. Is it possible to have the sub mounted on the outside when using a sealed box?

And

What do you use to measure spl???

Yes, you can definitely invert a subwoofer using a sealed enclosure.

SPL used to be measured using a microphone but it's more common now to be measured with a pressure sensor.

invert mounting increases effective box volume, but is prone to vent noise... this mounting technique should only be attempeted by experienced users who do not mount thier 6x9s with thier subwoofer..... [img]graemlins/laugh.gif[/img] [img]tongue.gif[/img]

Dude, what is wrong with mounting them with the subwoofer? The box has three compartments, The subs compartment is the perfect air volume that i need. And it is totally air tight. What is wrong with that?

Starterwiz

The most important panel of a subwoofer is the front mounting baffle.
As the pressure wave comes off the front of a sub, it hits the wall of stationary air in front of it. This causes the pressure wave to propegate sideways along the baffle, somewhat like a drop of watter hitting a puddle...the waves do not go straight to the bottom of the puddle, but rather out in rings along the surface.

As soon as you mount a movable object on that same baffle, you are allowing the wave to be absorbed by the cones of the 6x9s. They will move out of phase with the sub, and cause the bass to become muddy.

That's the technical explanation.

The real reason tho, is that it's just gay! [img]graemlins/thumb.gif[/img]

Having stereo full range speakers playing from the back of the car (2' apart no less) isn't exactly ideal from a sound quality standpoint... but there isn't anything really wrong with it so long as you are happy.... [img]smile.gif[/img]

Alright then, i didn't know that. I thought the 6x9's would add to the bass.

Thnx for telling me, now I have to build a new sub box. I have the plans but I am unsure if it is safe for the amp. Here are the plans: http://www.wakeskating.com/media/upl..._Sub_box_4.jpg Do you think the amp will vibrate to much and get ruined if i do it like this? Thnx for the feedback.

dont bother rebuilding if it sounds good to you . audiophiles like to have no sound coming from the back and thats not for everyone! some people do like the surrounded feel that speakers on every side give. before you rebuild try the sub with the 6x9's off or in a different spot and see if it sounds better. only then would i justify buildign a new box

Alright, i was thinkin i was gonna keep the 6x9's close to the sub anyways but i have to rebuild my enclosure because i bought another sub of the same kind and i had no place to put it using my old box. I have so many box ideas but i am not sure what will harm the amp and what won't.
