hey guys. I have four 12' kicker L5's that i'm putting in a sealed enclosure. I'm thinking i might invert two. I search online and know people have done this before. Room isn't problem, i just wanted your opinion on this subject. Thanks

Just make sure that if you invert them in the same box that you wire two of them backwards. This will get all the subs pushing air and sucking in air at the same time.

That's incorrect..Sam even when you invert them you still need them wired the same way.
You'll cancel each other out. The only way you'd wire them backwards is if you iso-baric 2 subs
and run them off one channel.

I think he meant instead of the positive going to the positives, have the positives on the negatives and vice versa, so that the cone travels the right direction instead of when its suppose to push air, its pulling it...

alright since i'm going to run the four with a 2500.1 amp then that means the inverted ones need the postive to the negative and the negative to the postive. Also if i do invert two will that change the sound, or the db's.

sams on the money. the two you invert, just flip the positive and the negative. as for the sound it really shouldnt change much. db change will be extremely minimal if at all.

Check this, let's say you have 2 subs on two seperate channels, the woofers pushes outward,
(away from the magnet), when current goes through them. When you invert one of them
(let's say the left one), they will still push, (away from the magnet), but the left will push inwards
and the right one outwards. Now running on one channel with the same subs, with the left
inverted and the wires flip, the left woofer will now go the opposite way (towards the magnet)
and the right will still push, so in other words you didn't really change anything as far as what
you are trying to do.

Hope this helps a little. I'm not trying to insult anybody's intelligence here but I'm trying to help you
picture it.

Thanks for the input. Your not insulting me at all. I apprecaite all the advice you guys are giving me. I have another question. I'm going to install at least one more battery and i was wonderin what you guys perfer for batteries.

Optima yellow. Check out http://www.gravanatuning.com

I'd suggest, if running two, get 2 of them at the same time so you don't have one weaker battery...I remember reading a while back that this will cause the weaker one to constantly drain from the stronger one, if i remember correctly....Might wanna wait for someone to come in and back this up or correct me if i'm wrong

you said the same thing that everyone else said.

"with the left inverted and the wires FLIP,"


you inverted one sub and flipped the wires on it.



if you flip one sub over the sub will push air into the box, while the other sub is pushing air out of the box. this gives you your cancelation. so if you just flip the +and- on the inverted sub (just the sub portion leaving the wiring at the amp the same) then you now have the sub pushing air out of the box the same as the non inverted one.



this is the exact same wiring setup you would use if you were doing an isobaric clamshell type setup. i stated clamshell and not just isobaric because there are three types of isobaric enclosures and depending on wich one you do will determine the wiring. there is an isobarric setup that has both speakers facing in the same direction in wich case you would wire both subs the same. so you should be more clear on wich type of isobaric setup you mean.

MJ Mac, first you say I stated it wrong, then you said basically the same thing I said later on.

Like everyone else said, including myself, you do need to invert the wiring on the inverted subs. Sorry I was not clearer on this.

Sam I guess I shouldn't say you were wrong. I thought 98blkz24 wanted to move more air and
normally that's how I would do it. If he wants to invert the subs for looks then it doesn't matter
how he hooks it up. Sorry for the confusion.

But now that I know he's only using one amp for all 4 subs he's not going to cancel any thing out
regardless of the wiring diagram.

how many accounts do you have lol.

it will still matter how he hooks it up.

If you are asking me, just one. I changed my user name/author.

It's cool, we are all friends here (I hope) haha!

I want to the local dealer today that i got my subs from and talk to him about this too. I told me the same thing but confused my little about the box itself. I'm building two boxes and he told to put one inverted sub in each box. So does this mean i should still build the box for 2 cubic feet per sub or just 2 cubic feet for the sub in the box. Sorry for all the questions, I just want to make sure that I build everything correctly.

well sealed if more forgiving, if your building a box with a common chamber then i wouldnt worry about it just build it to 2. cu. ft. if u are building a divided chamber and want to keep things as accurate as possible the inverted sub chamber will be slightly bigger because instead of the sub being in the box taking up space it now makes the box bigger because you gain the space that is between the surround of your sub and the box itself. if you made them the same i doubt it would make any audible diffrence to your ears but if it makes you feel better go ahead and make the inverted side a bit bigger, how big is dependandt on the displacement of the sub wich should have that size measurement in your manual for the sub.

If each sub needs 1 cubic foot, and you are putting 2 subs in a box, build it for 2 cubic feet, plus alittle for the inverted one. So, all together you will have 2 boxes that have a total volume of 4 cubic feet.

I am unsure of the specs for the L5. If they require more airspace in the box, just double the volume for 2 subs.
