SPL - DB's
 

Has anyone had their set up metered? I am trying to figure out what kind of numbers everyone is getting out of their system. I have a 2005 screw and of course I am limited on options if I want to keep the back seat in and not cut through the bed. So going as far as a seat lift, has anyone been able to get any decent numbers? :coffee:

158.5 on the new termlab sensor
169.3 on the old old audio control meter.
160.2 on the linear x

Haha, so do they sit on your roof?

I suppose you can get some decent numbers. Usually more airspace equals more output (to a certian extent) so depending on the subs you went with you might not have proper airspace to use as an advantage.

Under the seat your not going to have much depth, so your probably going to have to go with 10's. And Id shoot for one 10 in the biggest effective ported box you can fit under there. Unless you can fit two ported tens :).

And dont go "10'S!!!!!!!!!!!!!!! 10's dont get loud!!!" You would be surprised what a ten can do. Done properly of course ;)

sx's that makes me smile, I had 2 sx10's hit a 143.0 on the new TL in my old car. I doubt you'll be able to fit a 3 cube box back there without losing the seat. i'll let you all know what my 18xxx does when I get around to building a box for it

lol - ok...

1) nice numbers -
2) I am pretty sure that something like that is not going to fit in my screw and allow my seat to remain and be usable. Nice set up though :thumbsup:

Yeah, I know that it is quite limited under there. I haven't even started to measure the area back there yet but by looking at the prefabs they have available, it seems like it would probably be pretty tight (maybe 1.5-2 cubes) Lifting the seat might get it up to 2.5 or 3 cubes - maybe something close to that. I am thinking that I am going to have to maybe stick with a single sub and just give it a fair amount of juice. I don't know where I will go with it yet. I have run various set ups in my explorer. They all have their advantages. I currently have 4 15's in there with 4 more sitting in the house waiting to go in. Bottom line is - factory system from Ford in the F150 is definitely not going to cut it. I am having low end withdrawals!

:smoke:

P.S. "And dont go "10'S!!!!!!!!!!!!!!! 10's dont get loud!!!" You would be surprised what a ten can do. Done properly of course "

- My answer to this: Nathan Munson and 1 10" Digital Designs sub

Yup yup :) Thats funny that is exactley what I was thinking of when I wrote that.

What was it, 168ish db's? I cant remember for sure now. Damn impressive though.


Edit, found a dealio on it.

Nathan Munson Wins Extreme 1-2 at San Antonio dB Drag/NOPI Event: 169.8 with a single 10-inch Woofer
Wednesday, June 12, 2002 by Rob Granger

Authorized Directed retailer and veteran competitor Nathan Munson, owner of Eastern Audio in Clovis, NM, used two stock Viper d2500.1 amplifiers to power a single 10-inch Digital Designs subwoofer in his highly modified Civic to an astounding 169.8 dB result to win the Extreme 1-2 class at the triple point event last weekend.

Munson had previously broken the Extreme 1-2 world record with a single 15-inch sub early last season, and went on to record 170.8 dB, which stands as the loudest single woofer vehicle in the world. To top it off, his alternator failed between his first and second run, likely the only thing that prevented him from achieving a 170+ score with the 10-inch sub. As was the case all last season, the vehicle was powered 100 percent by Directed class D amp technology.

"Nathan’s consistent ability to hit big SPL numbers with seemingly any size or quantity of subwoofers is truly impressive," says John Durbin, audio product category manager for Directed. "He’s a consummate professional and skilled competitor, and Directed is proud to have him representing us in the SPL arena."

Heres a linky, little past halfway down the page.

Yeah that is sick - Just shows you how far install goes.. Unfortunately, that is going to be a sheer competition set up.. I have only been working with daily driving street set ups for quite a while now.. Sound quality wise, it normally goes over much better to spread the power out over cone area for a daily deal.. lol of course the screw doesn't leave much room for additional cone area.. I will probably have to find some kind of balance in between...
