I have to of the lower end Soundstream 15's (piccaso Series) and a ported box with a Rockford Fosgate 2500 watt amp pushing it. I recently went to a sound comatition and the best I got was a 144.....is that ok? I was hoping for near 150.

For a setup that you use on the street 144db is a good score. Many steet setups are only capable of 135-145db so your towards the top of a true street setup
There are a few people who have a daily street setup that come over the 150db mark but there is alot of money and time involved in it
we have been working on a 2 sub street setup that you can listen to on a daily basis, and also run shows with.
We are slowly approaching the 150 mark but it has taken months of time and design to get there

Jeff- If you don't mind me asking, what drivers and amps are you using on that setup? Also, how does it sound with music?

I am thinking about building a different box with two slot ports and maybe make it a little bigger. I also may eventually sell my subs that I have now and get some that are maybe a little more powerful. I'm not really one that like to fool with 0 gauge wiring and crap like that.....no need for 3 batteries and 3 amps and such stuff haha. I just want a simple system that will blow all of the local "gangsta wannab's " systems out of the water haha if ya know what I'm saying.

Running 0 gauge may be required depending on what power your amplifier requires. You can buy the most exspensive equipment you want but if corners are cut on installing it properly it will sound like poop or other issues (lights diming etc......) nouse is right also if you build a box for the speakers you have now then more than likely it will not be the right size for the new ones, just something to consider when spending the money and time to construct a box.

Right now we have 1 12" L7 with a kicker KX1200.1 on it. It does 146.3db @43 hz
It sounds about mid for what I would like it to sound like. It does the low notes for rap very very well, and also is very very tight for drums and bass guitars ect. but the actual volume for rock music is quite lacking.
I intend to get the box for one sub nailed a little better before I go to (2) L7's with (2) KX1200's for a stret setup...That equipemnt is reserved for comp use only right now.

144db is deafening and will destroy your hearing in short order. I really hope you are not driving around cranking a system like that... ------------- Support the12volt.com

Hey.....I am very good and constructing a box but the problem is the tuning......port size.....vent size.....all that stuff. I've tried and I will say that it sounds better than some other guys boxes but it still isnt what I want. Is anyone on here willing to draw me out some box deminsions that will be perfect for my subs?? And if so I would be willing to pay.........also I figure if I re-wire all of my stuff and make sure it is perfect and get a better box and make it vented I should hit near the 150 range....right?

I wouldnt expect to see more then a 2 db gain by switching boxes unless you go with a Pure SPL built box for comp use only then you might see a 3-4 db gain
150 is a real big # to go for without any aditional batteries 1/0 wiring or an alt upgrade
what type of shows are you competing in?

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Well a recent comp that I went to was at Jonesboro Arkansas.......for anyone that knows where that is. Anyways, I really liked all of the equipment that I saw and it was really interesting. Anywho....there were no 160's......I think 154.3 was the highest......that was with 2 15's and two amps....lots of batteries....16V wiring.....it was crazy, he beat out everyone in the Pro class (with like ten 10's or other crazy stuff like that. I just thought at the time that 144 wasnt good enough......I know my ears cant take much more than that haha it feels like a bomb is going off. But I would like to get 150 eventually

I'm not really sure.....The audiostore (Audio Expess) sponsored it and there were not any offical judges I soppose. A friend told me the went by USACI rules but I'm not really sure. I had 30 seconds with the mic placed near the windshield....all windows had to be up and your dB score was posted on a LED sign. Pretty much.....about 40 people lined the vehicals up......drove through the judging lane and after the mic was placed the were tested and placed in a division. I was in the Two Woofer division and dominated everyone for some reason.

well sounds more along the lines of DB drag rules to me, but if it is not a sactioned event, then I really dont know what the rules would be. I just dont think a wall in that car would be much louder on a meter then something in the trunk/trunk enclosed would be

Hey this may have something to do with why I am not hitting harder.......I have no wall in my box.....two 15's.......lots of airspace......one port that is of correct lenght.
