Looking to trade my brand new 9KV2, for a signle 10"

you see boostd ... we have been saying its all in the box forever now. Now you can see just how important it is. Hence why I was giving you a hard time about having ED subs in a JL box. I am very glad you got them sounding better for you... this is what the forums are for. Well done.

 

Three 8's sealed will not have much of an advantage over two 8's ported.

Having three subs is useless most of the time....adding another sub for a trio will not gain much

 

Nice job Boostd!!

 

how will adding a 3rd sub not add much.its another woofer so it should add SOMETHING right.
oh and that box looks sweet

 

Adding a third woofer and making a SEALED BOX.

Compared to having two in a CUSTOM PORTED BOX.

My opinion is that two subs in a custom ported box will be louder than three subs in a sealed box

 

Three ported with at amp will work awesome...build it.

Tune it to 35 with a big port....I would make the slot port like 2"-2.5" wide if you can fit it.

 

Can you not make the box any taller or deeper??

 

I do not recommend anything thinner than 3/4 inch MDF...5/8s is pushing it and bracing will have to be used and takes up internal space.

I would say go ahead and build it with a 1.5 inch wide port...then see if you get any port noise...but the bigger the port the better IMO

 

You can use 5/8 stock, it will work. But as Azn says, its not recomended. The gains in the box volume by thinner stock will be negated by the reguired internal bracing. And you wont gain much volume anyway without the bracing, and then the box will resonate which in turn will cancel out the bass and make it muddy sounding and then you will be mad and set the box on fire and kick your subs in and throw your amp across the road only to have it hit head on by an 18 wheeler which will cause it to bounce off your roof and then smash your niegbors car window then you will get sued by them and thetrucking company which will cost you 20 grand in fees. So it is better to use 3/4 inch stock.

 

yeah what he said....:huh: :lol:

 

Boostd...from your pics of your trunk you can make the box taller and a little wider...so more room for a bigger port
