has any of you gone to a spl (sound pressure sound-off ) in a xb or xa iam gone to one in nc on the 11 i have 2 12s with 1045 watts .with the same setup in my old car it hit
143db :D

 

I have 2 12" kicker L7's in an ported box, with 1200 watts. i've never taken in to a competition, but I've been thinking about it

 

I will be running 1 Audiobahn AW1508T with an Audiobahn A1500HCT pushing it. It should be pretty shaking.

 

Small car or large car?

I db dragged mine this weekend and I hit 133 with it. It sucked because I only had a song, not a bass track. I need to get Bass Mekanik or something similar to that.

To accurately measure your vehicle, first you need to know what your resonate frequency of the car is. You also should know what frequency your enclosure plays the best at.

When metering your car, you should always use a tone rather than music.

Also there are different types of meter s out there. B&K being the most difficult and the new Term Lab meter in a close 2nd. We metered a focus at work with only 1 10 in a sealed enclosure with a VR600D. It did a 129 on the new Term Lab.

 

129 is not bad for a single ten, what kind of box/sub was it?

 

Opps sorry, i meant 139, well a 138.6 to be exact....Dang my 8's hit harder than 129....

Anyways..it was a Crossfire BMF w10d (dual 4's) in a seal enclosure with a Crossfire VR600D running at 2ohms (the amp is 1ohm stable).

We were messing around at work so we lined up and SPLed my car and then a co-worker of mine.. He kicked my ___.. He had a focus hatchback.

 

it was in a 96 ford mustang 2 12s punch xlc in a sealed box with the subs facing the front of the car.it was at 72hz or 73 hz at 143db with a fosgat 800 4a at 400 rms x2
i ran the 12s in parallel on 2 ch bridge and the other 2 ch bridge with 2 6x9s and 2 6x8s i go to meca sound-off now got a ported spl box with 800 4a just on the 12s
400 x 2 rms

 

What kind of amp are you running? i want to run 2 12" l7's in a sealed in my box i was thinking maybe a jl 1000/1 amp @ 2ohm......it won't really be incredibly loud b/c i want to glass it in and make it pretty rather than all dB....the 1000/1 amp produces more than enough power to run the L7's but i don't really want to spend all that money....whats the RMS rating on that amp that ur using?

i have been running 2, 10 " memphis hpo subs in a sealed box using a memphis 1100d amp and been hitting a constatant 139.9db

i going to use a ported box this weekend and i will post my results after the show.

yes in my hot lava xb.......

 

well guys i used a ported box this weekend and i smoked my subs and only hit 137.1dbs but it was enough to win 2nd place , funny thing is the guy who beat me only hit 137.2 talk about close i should of farted in the car for the extra tenth.

 

man thats gota suck i go this sunday i will post score sunday night
that is a good score man

 

what organizations are you guys competing in?

 

i compete in the slap shows check it out www.slapshow.com

 

139 with one 10 sealed on a termlab? That seems a little steep... especially at that wattage... Keep in mind, real SPL should be windows up, doors closed mic on the dash or lower portion of the window...

I was at an IASCA world finals event the other day, and there were world record holders there... I remember the one talked about competitor had a single L7 10" vented with 4kW RMS and she was doing 137 on an audiocontrol sensor (new, dead on with the termlab.net)

Honestly, if you said vented, it's believable, but sealed? I doubt it.

 

On a side note, the termlab.net seems to be anywhere from 4-10db's lower than a capsule mic...

 

I did SLAP last year a couple times, took second at one show, stabilized my electrical problems and went to the next show and took a 1st place trophy.

My 151 in stock 2 was good for last year, considering it was only 2db's off of the stock 2 SLAP record... mine was tuned for daily driving, too...

 

i am in MECA (mobile electronics competition association, inc) i was in amateur sreet classes last year in my old car i than this year i wil be m2 modified class juts because of my box is higher than my back seat we put the mic under the plan ot the bottom ot the dashboard on the passenger side of the car then we can have any of our car windows or doors open then there is reality spl that is when u put the mic on the drivers seat 26`in height windows can be open but no doors can

I hit a 147db with my 2 12" m3 memphes and a 1000d memphes amp. My box is a slot port. I also have a hot lava xb #1140 :D

 

i want to get my box metered as well. i have 2 12" elemental designs a seires ported tuned to 30hz with about 1000 watts rms each. my roof and side panels flex pretty nicely and nobody has been able to endure sitting in my car listening to lil jon - bme click for for than a minute or two. definitely 140db+ though comparing it to other cars i have seen/heard get metered.
