With that power I'd do a larger sealed chamber, but I'm looking forward to see what happens. But I imagine it'd be hard to fit 2.5-3 cubes sealed and 3.5-4 cubes ported in a trunk.

Any charger worth a damn is going to be microprocessor controlled an shut off automatically...I'd never buy one that isn't. I use vector chargers, they made the ones for kinetik(maybe still do?). I have three of them now, love 'em. My newest one is the big 4/10/20/40, and it has wet/gel/AGM modes.

Just like any kind of box, it deepends on how it's designed. They(bandpass boxes) can be made to do any of the things you listed...

And to imagine I used to do everything by hand a few years ago. -
I'm still playing around with this new video setup with the intro and such...trying to use some sped up video to catch more of the designing without making the video overly long and boring. Triple 18" DC Audio XL's Vehicle: 1995 Jeep Grand Cherokee Chamber Volume: 16.5ft^3 Port Area: 225in^2 Tuning: 34hz Dimensions: 42" wide x 24" tall x 48" deep

Gracias! -
Let me guess...Michael J. Fox is your neighbor and he insisted on doing the cutout for you. I couldn't help myself...

Is that the SA-15 box I did for you?

What vehicle is this going in? -
Is this box specs okay for my two 15xl's?
RAM_Designs replied to nosho47's topic in DC Sound Lab - Big Bass on ANOTHER LEVEL!
With the power you have available, 3.5ft^3 per sub will be fine. I'd personally shrink the port area a tad so you can get a little lower tuning and have the same port displacement...up to you though. -

Thanks man. -
4x AQ 18" HDC's in a 4th order BP with adjustable port. Each sub is seeing 2.75ft^3 sealed and 5ft^3 ported. The port is removable and can easily be rebuilt for other tunings and port sizes if desired. This would make it easy to have a higher spl tuning for burps and a smaller, lower tuned port for some ferocious low-end output. The box is picture with a 46hz port.
-
With that volume, you're going to be better off going with some aero/round ports instead of taking up a ton of volume with a slot port and lowering the efficiency of the box. Up the height to 20" and use a double baffle, brace the hell out of the rest of the box, and you'll be good.

What kind of power are you running to each sub?

This 4th order bandpass will be going in the bed of a 2008 single cab Chevy. Inside will be two of the new model Orion HCCA 15's. Each sealed chamber is 2.25ft^3 with a common 10ft^3 ported chamber tuned to 46hz. As you can see, there is a removable panel at the top of the box to access the subs, and the port is removable as well so that tunings and port size can be altered to custom tune the box.
-
I prefer a lower tuned box, but it's up to you. I like having that low-end extension and despise having an obvious peak in the 45-55hz area.
-
2ft^3 for a pair is the absolute lowest I'd go. Once you start going too small with them you really sacrifice your low-end output. Ideally, you're want about 2.5-2.75ft^3 for the pair in a common chamber box.
