box plans for 3sav.2 8's.....single cab f150

[bigmescan]

alright guys what i have now is 2 8's and im adding another....the dimensions i have are 53x15x7 ....im looking for 36hz.

this is what i have now......i will mount the amps on top of box...and if need be i can go 55long and maybe 8in deep. i still want to fire port to passenger side. and i believe i can get a 4in aero. instead of the aero being in center of box side maybe go the the top of the box

damn wrong photo

[bigmescan]

and this sub atleast needs .50cbft

I would fire it at the B-pillar instead of the up at the roof. I agree that you can get a 4 inch aero but depending on airspace, I might suggest 2 3" if you can.

thats how i have it firing now. the actual flare is 7in but id have to put it at the top of the box on the side so it wont hit magnets.im just seeing if someone can see what they could do with dimensions im giving.with 55in i can still have batt on drivers side and still have 4in from passenger wall. but if i have to i can slot port on the side as well

You'll need 1x 3" aero per sub

So

3x3" aeros

2x4" aeros

1x6" aeros

My oppion is with 3 of these

2.2net@ desires hz

On 2500-3000rms @1 ohm

As you'll be 1.33ohm

You would also have him tune to 28Hz too though

i thought 3d4's would put me at 2.66 and im gonna have to upgrade the amp to probably a t2500.1

and i have no clue what you said bout the 3in aero. can you elaborate please

[CleanSierra]

P.S. I've been suggesting putting those amps above the box against the rear trim panel for a LONG time now. Glad you are finally getting the most of your space!

On another side note, which coil configuration are you running on the subs? D4 or D2s? D4s with 3 subs puts you at 2.33 and dual 2s would put you at the 1.34 like John said.

*Edit- I was typing before your response was there. I answered your question before I had seen you asked it?

To get proper sq. inches per cube on port area, he meant that each sub needs a 3" aero to satisfy GOOD port area per cubic foot.
