Who has had problems with the subs and the back of the seats? I don't want them to be rubbing against the back of the seat, cause that will cause more heat. but with the mounting depth of these death penalties, i may have to...

The plans for now are to build a false florr to get that annoying hump out of the way, stash the amps underneath that, then build a wedge box to go up to the window line.

~6 cubes, subs forward, ports up w/ 4 4" psp's.

i just ordered those so that IS what i will be using.

no, its extended. I guess I could make the bax have a depth of like 13...then I could even recline :)

why do you have a prob with the subs rubbing then? I fit 8cubes sealed in my 95 S15, firing forward, under the window line and could put the seat back G style.

box plans are 49 x 24 x 12, so ~6.5^3 before displacements, 6^3 after subs

Whats the displacement on those ports 17" long?

yep that is the main down fall you will lose leg room

I have my 9515 in a 5cu's the box sits on the ledge and goes all the way to the window line and takes up the whole length of the truck and is i think 12" deep sub forward on pass. side with 2 6" areos up on the drivers side the amps are on the floor partly under the box

I guess I should be fine. I didn't take into account that I could make it mush less depth...

I was thinking I would have to make it so that the ports would have to fir behind the subs, but I can put it on either side...so long ways(49") my box will go like this...

port, sub, port, port, sub, port

Really, I always thought that s10's were a little wider. I'm only making it 49" cause thats the width of the MDF :laugh:

now I just need to find some 1" mdf...

2 6's are the same as 4 4's

or i sould cut the 4's and make them a little longer i guess, but what would i use to legthen it?

and how far away from the bottom of the box should I keep the ports?

then make a fiberglass beauty panel for the opening.

Are you only using a pair of DPs in the 6 cubes and do you already have them? I'm sure you've told me before but I forget.

Ok. I was going to say if you didn't already have them look into the sale on the 12'' Nightshades.....they only need 1.5 cubes per. I think you'll be fine on not having the subs rub against the seat as long as you keep them relatively low on the box.

You can buy the Dayton port parts from Parts Express that are 4" with a flare on the outside and inside and they have tubes and elbows (smooth 90's) availible to make the ports as long as you need them. I was told to keep ports at least a port diameter (4") from any other structure to prevent adding an additional wind noise... Though I have found in my own install, that port noise is not very audible at all in a reg cab truck, with the port on the side of the sub box because it's so far behind the seat and all that you can't hear the noise. Just my experience with my ported truck box... i know yours is ext cab, you are luckly but watch the port size because you could get lots of audible port noise since there is nothing there to block/diffuse the noise (like the seat does in a reg cab...) 4 x 4" is probably more than adequate to defeat port noise for 2 12" subs... I believe you did say 12" DP's.... 4x4" might be a min for 2 x 15's though.... getting close to making some port noise with high power...

I got a lot of port noise in my reg cab truck with a single 3'' aero. It went away when I added a second 3'' though. But this was firing up and the port was inbetween the seats and not in a corner.

He said "sounded better" not louder... Does making louder always make it sound better also? LOL maybe to a hardcore SPL comp guy I guess.... My subs sounded much better forward firing than they did facing up...

I've heard controversial evidence with this. I've had tons of competitors do slot ports on the up,the length of the box, subs forward...they were metering 160+

Function of port area, if he uses a similar port area... then not a big deal...

Plus if he has 6 cubes GROSS to work with, then he has plenty of room...

"Jimbo" a world record holder in SPL comp from here in Texas (Bryan) has 3 x 15" RD's below the window line in his ext cab S10, subs facing forward and a long slot port across the top backedge of the box (just below the window is the slot port at the back of the box)....

If you take a router to the slot edge and even go as far as to fiberglass it, it looks great... That (Jimbo's setup) is a "record winning" box setup in ALOT of competitors ext cab S-10's that are "below the window line" because of their class restrictions...

Are the Aero ports less $ than the Dayton or Precision port kits from Parts Express? I always hear people refer to the Areo ports, but I don't see the difference, and I would think that if Areo port (isn't that Rockford Fosgate stuff?) where made by RF it would be more $$$ for the exact same junk.

Subs forward and ports up works well for SPL (thats how the usaci guys do it), however, I've never seen it done for a daily install.

maybe a little advice on the amount of port? will 4 4's be enough? or should I bump it up to 6?

I think you'll be fine. Rule of thumb with aeros is you can get away with half the port area compared to a slot port.

4 -4's will work just fine for 2 12's.

Slot port facing up will be loudest in some instances. If your building it for comp them you need to try several designs and see what works best. When using aero's you may find it to be loudest with the subs up or forward and the port firing to the driver side.
