How to make my trunk the loudest?

Change your name to terry brocks, get 4 DC XL m2 12 with two DD M4s. Oh and a burp box.

I will let my trunk builds speak for themselves.

Doesnt seem to be moving much air for a pair of 12s and a sundown 4500.

Nope not at all. Notice the heavy shirt

Seal them off into the cab

This.

This thread brings the lulz.

The easiest way to look at your little debate is sealed boxes. A woofer in a small sealed box is going to be extremely peaky with a weak low-end. The output of the same sub in a bigger box will be more flat and have more of a low-end.
If I had my computer I would post a pic of this in winisd.

To be fair, the only reason there ever was a dumb debate is because I was being pushed to say the same exact thing, in different ways, over and over. Keep in mind that I agreed in my original post that a larger volume has the potential to yield the greatest low end extension. Apples were compared to oranges, and now you're comparing bananas with the sealed boxes. Allow me to post some cliffs since this got convoluted so fast.

Apples - Same sub, same tuning frequency, increased net volume = higher peak (my position 100% of the time)

Oranges - Same sub, port size and length staying put, increased net volume = lower peak (was mistakenly assumed to be the position I contested xx% of the time)

Bananas - Same sub, sealed box, increased net volume = lower peak (your position somehow being the rebuttal to my position)

It can't get any clearer than that.

Convenience would have it that Kushy_Dreams posted a screen print that proves exactly this, minus the sealed box:

Peace.

what you people fail to realize, is that we are talking about a trunk here. a small box with smallish port area acts as the rear chamber of a sixth order... because that is what we are making the trunk into when we add a bass reflex enclosure. Now op may have to play with enclosure size to mess with the size of both the front and the rear chamber, but im telling you, make this one 2.5 cu ft, with a 6" aero firing to the side, subs forward.

Once you figure out the accoustics of your car's cabin winISD is a very accurate tool in predicting response. In the world of designing boxes there is absolutely no substitute for experience. You'll want to try a dozen different things for one car before you begin to get an idea how various things change output and response.

This.

Check my edits in my above post. You were the one who mentioned anything about the tuning changing. I said ALL things equal save the net volume right after you disagreed with me initially.. I thought that was clear enough. But, if it still wasn't, I apologize.
Sorry for the thread jack.

I think we are talking about 2 different things and just confusing each other, I'm trying to say a larger volume flattens the peak and gives a wider bandwidth and I think you're saying the larger box has a higher peak on the db reference scale. We are both right. I was all fucked up last night and I like to argue for the sake of arguing when I get buzzed.

I would do your own research OP and then figure out the best options. Basing ideas and thoughts off of a program with out knowing anything about the car will just net a result you do not intend to get. Now if you know the peaks and nulls of your car then you can use a program and design around them.

As for the 2.5ft3 for 2 12s with a 6" port. I do not suggest that unless you are just burping your setup.

This is truth.

If you are chasing numbers you will have a ton of builds in your future and you have no need to purchase a design from anyone. If you are into SQ, then the same applies. If you just want "loud daily" kind of setup then that is different and you likely not need more then one design assuming you get a decent one at first.

Fair enough bro. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
