Are walls always louder?

And is it possible to build a wall around an existing box? My current box is already just about the entire width of my cargo area. This is in an 08 tahoe.

No they are not always louder.

What are your goals, and what is your equipment

Might want to rebuild your box with proper amounts of port area first dude. At least 5-6 times that port area...

wow yeah u may coulda got by with like 80 sq in if u had lot less power but with 4.5k u need a min of like 116 sq in i would think.. maybe @shredder2 can model that box for u..

Thats 22.5 per cube so 180. No way im getting 5-6 times more.

lol not per cube we meant total.. is the 8 cf ad or total box size?

 

[KilluminatiDre 10+ year member]

Sorry hard to see the replies while driving. 8 cubes after displacement and 180 sq ft total port area

 

[BOOMINGRANDPA 5,000+ posts]

shoot for like 15" per cube until someone can model that box

 

[KilluminatiDre 10+ year member]

15 per cube is less than what ID recommends. They recommend 22.5 per cube which is what i have.

then you should have put port per cube not 22.5 sq inches of port area. There's a GIANT difference between the two.

You have too much port area with that lmao and no their recommendations are not what gets you loud. Port area is relative to your input power along your vehicle acoustics. Just going off blind manufacturer recommendations already means you have a super sub par box thats not anywhere near a proper custom ported

Also you seriously fked up, The manufacturer recommended 22.5 sq inch PER 15 not port per cube.

May or may not help. Sometimes loading the port into the rear or side works very nicely and if you're not prepared to build a proper wall and do some tweaking simply aiming everything forward and building some trim pieces around the edges may just as easily hurt as help.

Also you seriously fked up, The manufacturer recommended 22.5 sq inch of port area per 15 aka just the opening of the slot port not port per cube never did it ever specify port per cube, just look at the aero port recommendations 5 inch aero x 16.4 how much port area do you think that is. Box rebuild or port modifications is seriously needed with your enclosure plain and simple. Way too much port area can cause the subs to act like they are in infinite baffle costing a fk ton of output.

Yep... 45in2 of port for both... "recommended"... hah!

With a port that large you may never get the subs to move enough to "use" the port

I had a single 18" in a large box with a huge port and anything under 3k and it fell flat on its face. But once I started to add more power it came alive. Was working good and not like a box with a big hole in it

You could try 2 or 3 6" aeros
