putting the port across the top instead of the bottom (still firing forward) would not be louder on a meter. Firing the box up with the port across the back (by the back window) would be louder on a meter.

I dont think he is listening.
oh yes he is...

TTT
.....anyday now.

It would have to be a level 3 8". The diameter of the motors for the level 4 and 5 are too large. http://www.stevemeadedesigns.com/board/public/style_emoticons/default/dirol.gif

Why dont you make any 8's???
Make me some level 2 or 3 8's. http://www.stevemeadedesigns.com/board/public/style_emoticons/default/hairtrick.gif

Use the resonant frequency of your car to level match gains. If you dont know it then 50hz is a good choice but it doesnt "have" to be 50.
.....and higher frequencies do NOT draw more current. Higher frequencies = less current.

If sub is up....port to rear or front?
rear!!!

Hertz

yes...assuming they are all 12v batteries. All positives together and all negatives together

What kind of boat?
Bring it to Lake Havasu. I can make it loud.

Its true. Your only hope is to port it and tune high. (40ish)

3 18's sealed or 3 15's ported

That room looks like it needs a drum kit
and dont forget the cowbell.

Ummm. I'm a little confused now...there are different answers here...so i should get a mono amp with 1200 Rms or what?
get an amp thats rated anywhere from 1000 to 1200 at 1 ohm mono and you will be fine.
-
how did u come up with this 1.33ohms from??? thats only if they are Dual 2 Ohm Subwoofers 1.33 Ohms would be achived in Series/Parallel.
1.33 is correct.
a single 4 and a dual 2 has the same final impedance if the dual 2 coils are ran in series.
-
that amp wont work. You need one that will run 1 ohm mono.
....and who the hell is okcchad?? there can only be one person on here from okc.

typical astro box in it.
*ahem*
.....and i dont have any cash but id like to come kick your tires.

I am pretty sure its your port....
+1

Definately the Memphis 4Kw's.
I can probably get you a better price.
-
good choice
40Wide X 16.50Deep X 15Tall
38.50Wide X 1.50Tall x 13.00Long
subs up firing as far forward as possible
slot port across the bottom of the box firing back.
Divide the center of the port with 3/4 to brace it.
-
By making it 20 deep, does that still allow some room for a rear firing port? or is that all there is?
If you only have 20 deep to work with, 2 12's would be louder than 2 15's.
I dont like doing "swappable" port systems because there is no way to get the full potential for spl or for street beat. Both will be "half assed" IMO. The best thing to do is tune somewhere in the middle so its as loud as possible all around.

Do you know what shop in Indiana it was sold to
H&K or something like that.
-
Do you not have the astro anymore
nooooo...that thing is LONG gone. I sold it to a shop in Florida then they sold it to a shop in South Carolina who then sold it to a shop in Indiana who then sold it to someone else. No idea where it is now. Its junk now.
