AC is around ~5-8dbs higher than TL.

Also Kick and Seat(Watever this maybe) is 2 WAY different things.

Kick is gonna be louder 99.9% of teh times.

how would it explain me getting 135 dbs of a amp that was puttin out like 800rms to a amp that is putting out close to 2000rms and only 140 on the AC

well when they did it with the AC they had my doors open, and he put the mic on my seat and it moved around..., he didnt put it in the kick panel

Your Hifonics amp isnt doin 2000rms either.

Im telling you. AC is not that close to a tl.

DONT CARE about what you say.

IT HAS been tested a millon times, I doubt this one time is different from u.

You cant compare to 2 different locations, on 2 different amps, and adspect to even think of gettin results.

From back in the day i was told (havent verifyed this myself but seems to fit what you got) that unless you were grossly underpowering your subs before, if nothing else changes and you add 1,000W its only gonna give you about a 3db gain.

Sorta makes sence. Your box isnt getting more efficient, and your not adding more cone space. your just moving the same subs just a little more then you were before.

yea but you should also hear a 3 db difference...it sounds much louder now than it ever did, and i bet this amp is putting out close to 1600 rms...i just bought a hifonics xx-hercules, so that SHOULD put 2000 rms cause its at 12.5 V rating, mine sits around 13.0-13.8

i think i might try and build 2 boxes, both 2.0 cu or bigger tuned to around 33-34 hz and if i dont like that, would i be better off selling the 2 12's and getting 1 12 that will handle 2000 rms and have good spl and sq? would it be louder since the box would be more proper for a 12

with 2 boxes you waste alot of air space in the middle (all the 3/4" wood) and then again with both of the porting being seperate, I got a desighn up now, gonna take about 30 min to get it in paint I think.

ok cool, what im goin to do is a take a picture of my trunk tomorrow, and take measurements because i know i have more than 4.0 cubes but the trunk is thinner at the wheel wells sent me your email or i could always post it up on here...

What kinda electical upgrades do you have?

 

[DarkFox 10+ year member]

dont feel like going in and chaning it but the effective port lengths are 18.75 and 11.25, though all the cuts are the same, I got it wrong in the pic.... I used paint and 1/2 an hour.. meh.

 

[cocoleveo7686 10+ year member]

will 3.66 cubes be enough for 2 12's or should i just build a box and put 1 of my 12's in it...i dont have alot of space to work with which sux

and i have a stock 110A alternator, big 3 in 0 gauge, and a yellowtop up front...

3.66 Can be enough.

Do you have pics of your current box?

Also, your in a trunk right?

 

[DarkFox 10+ year member]

3.66 will work, the main thing is your loosing some off your low end, but the box has a good gain and nice decent. I usualy try to get the cutoff freq lower but you should be all right.
