carshateme Posted April 13, 2012 Report Posted April 13, 2012 Never really done aero ports that much, So does this look right? The port is going to be upward through the back deck, firing into the back glass to eliminate port noise. The port is going to be kinda in front of the subs...or should I have the subs pointed towards the back..? New build coming soon.

Lbox88 Posted April 13, 2012 Report Posted April 13, 2012 Port is waaaay too small. Try to keep your port area within the suggested "Port Area Range" right above it. Usually ends up being between 9-12in2/ft3. Also, I think the port length needs to be both the internal and external length, but don't quote me on that. UBL | Build Log
carshateme Posted April 13, 2012 Author Report Posted April 13, 2012 Yeah, I noticed that...the external port wasn't affecting it whatsoever. New build coming soon.

carshateme Posted April 13, 2012 Author Report Posted April 13, 2012 I changed it up, Since the external doesn't matter, I'll just move the port 5 inches up so it's attached to my rear deck...gonna be a bitch cutting a circular hole that big.. New build coming soon. [center][url="http://imageshack.us/photo/my-images/3/sigtoo.jpg/"][img]http://img3.imageshack.us/img3/9541/sigtoo.jpg[/img][/url][/center]
Sergeant_Skyrim Posted April 13, 2012 Report Posted April 13, 2012 Yeah, your external port length can't be longer than the value you enter for port length. And like the above said, make sure you give it enough port area otherwise you WILL hear very much port noise EDIT: Ninja'd by OP Build in progress
Sergeant_Skyrim Posted April 13, 2012 Report Posted April 13, 2012 What size subs are you using? I see .32 for woofer displacement, but only 2.44ft^3 net internal volume. You using some beefy 10s/8s? Build in progress
jrchevy87 Posted April 13, 2012 Report Posted April 13, 2012 You have to account for external port as an internal port will occupy some of your internal volume Jeep Wrangler TJ Hardtop Build
carshateme Posted April 13, 2012 Author Report Posted April 13, 2012 2 DC level 3 12" subs. Being overpowered by 200rms, thus I'm making the box a wee smaller so I can have some more room in my back truck for my batteries and amps. I will be L porting the PVC pipe in the box and putting it 3" away from the back wall...thus leaving me with a little over 10" for the outside port. New build coming soon.
