X15 loudness question

[revoracing247]

it's your electrical and also your box could be bottle necking it. whats the port area on for the box? i have 70sqin for my x15 and im planning on building a new one with more port here soon.

I've got 50-51sqin port area. Have window brace and double baffle so I know the box isn't warping.

An X series driver or any of our new platform drivers specialize in being loud over a large bandwidth (eg: staying loud down low). They also may not SOUND as loud at a given SPL due to significantly reduced mechanical and suspension induced 2nd order distortions. A clean level of output will always sound quieter.

I am running ~2k on mostly stock electrical as well, but my lights don't shut off lol. To protect your amp, your sub, and your car, get yourself a cheap volt meter (yes the Stinger ones work) when you see that you are dropping below ~11 volts (you will get different opinions on the threshold here) it is time to either turn down the volume, turn down the gain, or upgrade your electrical.

Ie. on my setup I have gain properly set (with bass remote at max) running the amp at .5 ohm. On normal music I leave the bass knob at the minimum. When I want to turn it up, I watch my volt meter and when it drops below 11, I back the bass remote down until I am holding around 11 volts.

I have stock alt, big 3 done, and an older Optima blue top under the hood with no secondary battery. Yes, this is janky electrical, but until I can buy an alt and another battery, it is what I am stuck with lol. I am protecting my gear and still getting into the lower 40s like this. The cool part is that I know there is more potential there once my electrical is straightened out.

And I am guessing I am not really giving much up in terms of SPL right now. I can crank the remote so that I am making my lights blink, but it isn't much louder (due to less volts in/less watts out) than running at a pretty steady 11-12 volts. I also have the advantage of having a little more power than my subs need anyway (1200W worth of sub and a 2kw amp (@ 1 ohm) running at .5 ohm.

Load test your battery and if it fails, replace it first. Big 3 is easy and not that expensive. You need about 10-15 feet of 1/0, a couple of fuses, and some terminals. With a low amperage alternator even CCA would do.

Could it maybe be because of my port area? Im looking into trying a new box but not sure what all should be changed

Didn't even think of the volt meter. Should of bought that awhile ago.

Thanks for the input

Up the port area to about 60 but keep it tuned to 32

It's goin in my ext cab truck in the back seat area. So keep the tuning you think

The real issue is your electrical. Those bb2400s are built good but it's gonna die on you eventually due to poor electrical my man. If I were you, I'd work on that before changing anything else.

Ya it's a different box. My amp right now is a bb2400 running at 1ohm. Stock alt, stock battery that has died on me 20+ times in the past year on me. No big 3. Pretty much stock everything. I'm just trying to figure if my amp is bad. It's definitely had years of abuse.

An amplifier doesn't create power, it converts it.

If you give it a limited electrical supply, then your output will also be limited.

Proper alternator, battery(s) and wiring should always be your first step.
