Wanna try something

[Face of Fear 10+ year member]

I wanna know if its possible to build a ported box for 2 memphis pr 12's that will fit in the back of a grand prix that can push my db's from 141.1 to somewhere around 150+. I tried this box designing program called WinISD beta and it said if I built one double sized at 55hz I'd hit anywhere from 152-154db ranging from 50-60hz, but still somehow I don't trust that program when I seen it say that. Something just seemed a little fishy. I'm pushing 700 watts through the subs. I've seen 144's hit with the subs, but im looking to see if its possible to hit 150+ with them. If anyone can help me that would be much appreciated. Thanks.

Well any ideas how i can hit at least over 144? cuz i've been stuck at 141.1 for about 4 months now and its bugging the shit outta me.

Need to know more about you setup. pics might help a lot and where are you getting meterd at by the way. Kind of want to know where some are in iowa

well how bout somewhere between 144-150 so im not stuck at 141.1 anymore? cuz im kinda annoyed with being at the same place no matter what i try.

I'm pushing 2 memphis pr's, ported enclosure(tryin to build a new one) tuned at 50hz. Crunch 2000.1 groundpounder. Eclipse cd2000 and a 12v linedriver. system is running off mflex 4guage wire.

I'm testing outta mobile wiring out in davenport, iowa.

was that on a term lab meter?

new subs/box/amp? But then again if you have to ask something like this your not going to get anywhere near 150. do some research. look at some real systems on here that hit 150's and you will see what it takes.

**** no. they are getting a term lab before this coming summer. They got some old school tester. That could be why alot of people were hitting 150+.

That is probably one of the worst sounding substages ever to grace my eyes. Memphis power refs off a crunch amplifier, tuned to 50hz. All you're doing there is farting. Get rid of those subs, get a good, solid 1500-2000W amp and throw that power on one GREAT 12 in a GREAT custom designed enclosure, and you'll almost certainly be hitting higher.

ive watched 2 m1 10 on 1000 watts hit 153.4 and they arent to much better than the pr's so hitting near 150 shouldn't be a problem at all with the right setup.

use bigger power wire, add a second battery, buy better subs, find out where ur car itself peaks instead of just building a 50hz box that won't help u get any louder, make sure ur actually getting metered on a REAL term lab meter, get a better amp, seal off your trunk...or use some kind of silencer....all of these will help you out.

also do not jus build a new box at 50hz lulz

Then that likely means that you aren't hitting anywhere near a true 141.
