should i do it? 2 18" bl's in 16-20 cubes?

they're not fully loaded bro. they only have the cooling option (the limiter is the suspension of the BL's as they are even stiffer than the MT's). the amp is a kx2500.1 with a birthsheet rated 2960w @ 2 ohms, being ran @ 1 ohm so the subs are getting 1500w+. just as a comparison i saw a birthsheet of an RF T30001bd put out 2840@ 2 ohms and 3758 @ 1 ohm. doesnt seem like a stretch that this kx has the capability to put out lots of power for the subs if it putting out even more @ 2 ohms than the RF did (which is being ran on 2 18" mt's).

I love how people always just assume they are getting more than rated power because they are running their amp at a lower ohm load.

Get with the program people.

not like it matters what i assume. with box rise im well over 3 ohms at my lowest point anywho.

i have my gains set to "give" the birthsheet rating (2.9kw @ 2 ohms), i was just saying that i hardly believe the reason for this issue is underpowering the subs and gave what i would consider a fair example of why.

my kx's birthsheet says 2.9kw and in most cases its safe to assume a lower load will result in more power, because in general it will bring the rise down as well. if im @ 2 ohm and rise to 4 ohms...its somewhat safe to assume that being wired down to 1 ohm will give me a final load of under 4 ohms, which would mean more power. no one said since i was wired down lower i was seeing 4kw

More power, sure. More than rated? Probably not.

And I also agree that the current box is too tall. 2 15's would be the better option IMO.

2 15's, imo. More cone area doesn't always mean better.

i really wish people would of told me that earlier //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

i knew it was going to be tall but it seems i got some bad info in my last thread which resulted in me figuring it would be ok.

oh well. anyone want to buy some 18's?

I would try something like this, http://www.caraudio.com/forum/showthread.php?t=246572&highlight=kicker

or this



Seems to me they just need a little more breathing room in the back of your explorer.

That's the box I would build but with a slot port where aeroports are but with dividers in it to give the port and bottom of the box some strength.
