    Cool! I have never sat in a REAL sq vehicle before, I will look for you if I make it. I shouldn't be too hard to find...

    I just spent the last few hours playing with a customer of mines spl truck.... I seen plenty of spl trucks in the past, & I even stood next to mark facuda's blazer after he won the new world record way back when... hit 156 I think.... I'm guessing at least 15 years ago or so. today I guess many guys top this easily, but back then this was world record....

    I never really understood spl... I mean it's just noise I thought, has nothing to do with music.... I'm a sq geek really....

    boy has spl equiptment improved though..... my friend tells me hit hit 155 on a good audiocontrol rta at a local trophy party...

    this guys truck has 4 jl 13w7's & 4 jl1000's & a few other amps & drivers all over the place.... 2 huge alternators & six batteries... I painted the truck in my shop, 2 tone grey with a house of color candy blue stripe ...

    I sat in it & man.... what a rush.... intense...... when he closed the windows the sound pressure was so high that the windshield wipers were jumping like 4" in the air.... from outside the truck when it's cranked the rear doors can't resist blowing bending out kinda & the roof jumps up & down like crazy.....


    he has tv screens all over the place.... 10.4 dropdowns all over, moulded in screens in the doors... a huge screen in the center of the dash....

    none of his screens work anymore.... he tells me when he takes them out & opens them there full of schrapnel... the boards vibrate apart & theres solder & components broke all over.... he can't keep the screens going it's so bad, & he's giving up replacing them, but he'll do the main dash one to keep it fuctional

    now heres where it comes in what this has to do with this thread.... I heard a lot of hype about this truck before I sat in it, one told of how he thought it felt like you were getting kicked in the head with a size 10 timberland... another of when it was cranked a guy in the truck opened the door so quick & was so blasted that he just feel out of the truck..., by the time I actually sat in it, & yeah it was pretty intense... but I was kinda disapointed.... I think I wanted to see it so bad it crushes, but it didn't really..... I could take it..... & I could take even more.... I wanted more...

    I can see the adiction..... after spending a little time in this truck it makes me want to build one that REALLY crushes.... maybe not bad enough for me to ACTUALLY do it, but if I had more time & less projects I could see doing this.... & I really prefer sound quality over spl for the most part.... but pretty intense....

    Not posting this for anyone in particular, just for those that are curious as to how it works.

    Frequency has alot to do with it, 160+ db at 60 or 70 Hz is not nearly as violent as 150 at 40 Hz or below. Most spl cars are tuned near the cars resonant frequency, and if it is a smaller car the note they "burp" at will be pretty high. Higher tones (60 - 80 Hz) take less power to get loud, but are obviously not as fun. Also, being tuned that high makes playing music pretty much impossible (talk about dedication).

    I could type more but I will wait and see if anyone cares...

    The 13w7 is an amazing woofer, great compromise of sq/excursion, but is not an spl woofer. My old subs took 3500 watts each (rated at 2000), my new subs are rated at 8500 wrms and will be starting at 5kw each, but I have heard they can take 10k+. In extreme class, single subwoofers have handled closer to 20k.

    Some good spl makers are Digital designs, T3 audio, Resonant engineering, and Atomic, just to name a few.

    156 is something that the folks in the stock classes are hitting now...lol

    the mid 170s and I believe the 180s have finally been hit.



    hell, I hit a 149.8 in my car in the stock 301-600 class...lol

    Yeah, 155 on ac is not loud with 4 subs, I'm sure his truck looks very nice (new paint) and sounds great, but I would not consider this an spl vehicle.
    The paint probably cost him a few dbs (spl is a very complicated beast to tame).

    Another great site is:
    www.termpro.com home of db drag and makers of termlab sensor

    Feeling post happy this morn...
    Don't want to give the wrong idea with my previous posts, high quality equip and kw of power are definately good things, but spl is 90% install, (as stated by snoopdan and redgti) probably even more install dependant than sq.

    As with any new concept, research is everything, anyone seriously considering starting out should first:

    1. research
    2. buy a spl mike
    3. be prepared to build and test, build and test. If you are bit by the bug, your car will probably never be done.

    Do not jump right in with loads of deadening, and new shiny paint - these things will most likely hurt your score.

    woah there killer

    SPL is in no way more install focused than SQ. They are BOTH highly dependant on the install.

    I call it an spl vehicle because that's what he calls it & that's his intended use..

    the guy who built this truck is no pro, not by a long shot... he's a maintanance worker & did all the work himself with the system... I give him props for his dedication & effort... most of the customers I have with the baller trucks, filled with screens & rolling on asanti's & bags are drug dealers or just rich, but this guy is just a hard working joe(his names even joe ).. he skips vacations & still watches a 27" tube tv at home... he makes a lot of sacrifices to fullfill his passion with his truck

    I'm sure he doesn't even know what a resonant frequency is, let alone how to take advantage of it, & I'm sure he doesn't even know how to properly burp his truck for max reading... he is just a small time wanna be in the grand scheme of things, but this is part of what impressed me, that he could hit the 155 playing a bass track with off the shelf common equiptment...

    he now has desires to hit more real shows, & I know when he does he will see that he's not going to be all that compared to what's out there.. I don't have a lot of experience tunning for max spl as this has never been a desire for me personally, but to help guide him, what is the best way to determine what the target resonant frequency would be for his truck? I don't know how he calculated his ports or enclosure really & I don't know how far from optimal he is.... if someone here could tell me what advice to give him, or what to try to help increase his output I would gladly pass this along to him...

    also, stupid question, but how is it that fancy paint & excessive deadening hurt his score? is that a joke or are you really serious? I'm assuming your joking on that one, but asking anyway to see if there is something I'm missing...

    I do know that there is much more killer equiptment out there than w7's & jl 1000's, but for what they are they still impressed me... now I wish I could sit in a car that hit's in the 170's.... I'd love to know what that feels like....

    also, I do have an rta myself, but it only does spl up to like 130... what's the best way to get higher readings without spending a fortune? he doesn't have a way of mesuring himself, & only gets a reading when going to whatever smaller shows he goes too..... it would probably be in his best interest to be able to mesure his spl himself, but I don't know what to tell him to buy.... I doubt he'll want to spend a few grand on an audiocontrol high spl reading rta... is there a cheaper way to do that?
