I tossed away $15 to someone on another forum almost a month ago to someone who said they'd do one, and nothing yet. So i'll try here. So here is all the info, if there's something else you need please let me know, thx.

1. Car. Year, Make, Model:

2010 Avalanche

2. Subs. Make, Model, Size, How many:

4 15" CT Strato

3. Power. How much power per sub:

800-1K (1CT3K)

4. Goal. SPL or SQ:

SQL

5. Sealed or ported:

Ported

6. Sub/port placement:

Center, but open to opinions.

7. Max dimensions: 49"W x 20"H x 48"D (I'm good with the 49+W & 20"H, but shorter is better with the 48"D. I'd like to save some room in the bed.)

8. Desired NET vol and tuning(optional):

Open

9. Finish:

Raw

We're u wanting subs firing up and port on the bottom

Firing forward in a "V" shape with the port in the middle is what I was thinking. But i'm up for suggestions.

No specific tuning

No specific tuning

Looking for around 30Hz-32Hz

Wait, you want four 15" subs to face forward with only 49" width? That's not possible with only a 20" height. Am I getting your height and depth confused?

Really???? Your not very creative are you, lol. There are a number of ways you can make them fit if you think about it, lol. I just want someone to come up with a good box diagram for me that will be the best application for these subs. Boxes don't have to be completely square.

Sure you can mspaint that real fast but you're talking about losing a lot of air space, sacrificing a lot of port area, and you still might not be able to fit 4 in a row. I'll see if I can squeeze it without compromising performance but it's going to take every inch of space I bet.

After trying for a little bit, this design seems compromised and possibly ghetto as hell. It has barely an airspace per sub, not very much port area, tapped horn properties but they're very compromised, and unequal loading on the drivers. I wouldn't put my name on a design like this that I have no way in knowing what it will sound like. It could be decent and it could blow donkey ****.

Maybe this picture will give you an idea of how big two 15s are compared to your max dimensions. Especially if you're trying to squeeze about 3 cubic feet tuned to 30-32... a bit ridiculous.
