two dd 9500 15's or one dd redline 800 18"?

But I also haven't sent the sub off yet because I dont know how much shipping is going to be.

Well, if they're in Oklahoma that shouldn't be too bad of a shipping charge anyway.

Are there no car audio shows or groups around you that you could connect with? Seems to me you really need a bit of direction, encouragement, or help from some more experienced people. There's not much room for "upgrade" from DD95 as far as efficiently playing loud so I don't think just throwing new gear at it is going to be your silver bullet here.

Post some pics of the single 15 box you have in there. Absolutely no reason you can't be doing a 150 with that in your little hatchback.

Honest question, can somebody do a 150 with a single 15 in a small car? I want to get my car metered. How would I get the highest meter? Doors closed? Doors open? Doors closed? Which music or tone? I have a single 15 in a small car. Where should the meter be mounted?

If you care about numbers you MUST own a meter because to figure out any of that other stuff you just need to start testing. DB Drag meters with doors and windows sealed and the meter on the windshield passenger side, something like 12" in from the side and 6" up from the dash... If you care you can print out template for the jig and use that to find proper placement or if you go to a good show they'll often put a little round sticker on the windshield where it's supposed to be.

USAC meters with a door or window open (typically driver's side will gain something) and possibly the sensor down on the floor in the passenger side. Whether this gains and by how much is very install/vehicle dependent.

Not sure how loud a bug gets but other tiny cars are notorious for getting loud easy. CRX, Yugo, and Panda are pretty famous for it and some orgs even put them in their own class they're so efficient. The caveat being your peak frequency is generally very high (mid to high 60hz) so without a purpose built box to play that high tone you're probably not going to do anything really astounding on a meter.

So, you already know that I have a 95 amp alternator. What is the best number that I could hope for?

Alternator isn't necessarily the limiting factor for a 3 second tone provided your battery can provide that much. Really your whole setup isn't optimum for numbers from a box you can't move, to high tuning, to an amp you can't wire down to stupid low impedance, so you lose a lot of options for things you could test to gain a few tenths here and there.

IF you can get the old SPL lab app working on an Android device (or pay the 6$ to download the new version on a new device) I'd let you borrow my meter for a bit if you pay shipping. The catch is the new app is pay to download and the old one you can find for free doesn't run on new versions of Android.

You nailed it lol.....I do need some direction and encouragement..im like a balloon when you blow it up and let it go. Thats my thought process lol.

This box for the one is 5 cubes tuned to 36hz with 60 in² for port area. 5 inch port. I will post a picture as soon as I make it outside here shortly lol.

Do you even know which sub tgat I'm running?

It really doesn't matter. If it were junk I'd have remembered so I'm going by the assumption that it's one of the better Chinese cookie cutter ""brands" which should all get you about the same place.

@shredder2 designed me the box for my power and alfernator. What do you mean a box that I can't move?

A box that you can move meaning just that, a box you can move around in the cargo area, flip it to fire the sub back, port back, etc. etc. You've got zero wiggle room to change box position compared to a traditional fartbox that's going to be basically a cube with a big round external port.
