i have

12 - 10 inch MA Audio MA100XE subs

4 - 7 inch Phoenix Gold component system

2 - 6 1/2 Phoenix Gold inch component systems

2 Phoenix Gold ZPA 0.5 amps

1 Phoenix Gold tantrum 1200.1

1 Phoenix Gold ZXti475

alpine deck

alpine cd changer

5 optima yellow tops

all phoenix gold wire

Looks really nice.

Shop built I see.....says "Freemont? Freemond? Free...somthing?"

I woulda stuck w/ the JL's or swapped em out for newer ones.

I'd say if you wanna get louder but keep the same setup/box/amps/etc you need to put the most efficient woofers in the enclosure as possible.

I'd go with some Elemental Designs eD 11Ov.2's in there in place of those MA's.

Another option would be cut ur sub count in half, make one of the sub holes for each pair a "10in plate" with a port in it so you could run each sub in a 1.2cft ported box and see how loud that gets.

Would cut down cost buying 1/2 as many subs and you could use the same setup.

Otherwise it's rebuilding time buddy.

well if i were to port it, there is some space under the box, would i got for some like 3 inch pvc tubing? would that work?

It would depend on a lot of variables.

1: what subs you run (the MA's, the eD's I suggested, the JL's, etc)

2: How much room you have/how long of a port will fit-the TOTAL VOLUME of the port is what matters so you have to consider how much air the port itself displaces, how much the sub displaces and tune the port to work that LEFT OVER (net) amount of air in each box.

I would suggest either PCV tubes that you could use 90degree bends to make the tube/port fit or else a custom rectangular L shaped port that would look pretty nice IMO as a diamond (tilted square) port next to each sub. maybe 4"x4" x12-16 or so. You gotta do the math to get it right tho, or throw the numbers through a box design program.

well i was thinking porting it like this so i can have it fairly hidden, there is a small flap in the front of the box that stores my jack and stuff in there so i would just take all that out, but this is the idea.

a 3 inch tube that all run together from each chamber into one collector, like some headers. or something. what do you think.

setup is very sexy. i like it all lit up

"Looks cool n all".....but it's not acoustically sound (pun pun)

A port like that^ would cause the sub farthest back (towards the rear of the vehicle) to "see" a veeeerrrry Loooooooong port, and the next closest to the front would "see" a shorter port and the 3rd (closest to front) sub would "see" the shortest port.

At least that's MY "amatuer-ass" assessment of that design, any of my fellow SMD "Box heads" can help me out here, I HAVE stuck my foot in my mouth b4, it is pretty early and I have had no coffee yet....

But I still think that design would not work as you think it would.

You need to port each chamber SEPERATELY at least, and Identically if you want the output to "add coherently" aka reinforce the output of one sub to the next so they add up rather than cancel each other out.

Thats not gonna work my man. The way that drawing is, every chamber has its own tunning since the lenght of port gets smaller . It would work if each champer had the same amount of port lenght from each opening. And since these are small chambers, the port shouldnt be too long at all
