Do any of you compete with your systems or even just get them metered? IF so, post what gear you have and your score, I think it'll help a lot of these newbies out who know what kind of results they want but don't know what equipment they need to achieve it.


2 - JL 12W3's (dual 4's) in a ported box tuned to 35 Hz
(Resonate frequency of our cars with your box facing backwards approximatly 6" from the back is around 45 Hz)
1 - Eclipse 34230 Amp (rated at 370 x 2 into 4 OHM)
2 - 1 Farad caps


no extra batteries, no special alternator, in fact usin only 4 AWG wire since the system wasn't orginally intended for SPL.

Posted: 149.8, 149.9, 150.1, 150.8 in that order (I think I still had enuf juice to get it louder but that was enuf for 1st in the 0-250 dB drag racing class)

the last time i compete, i just had subs and mids, and hit 135, but now i can probably hitting 140 or a lil higher, there suppose to be a iasca competition this weekend but not sure if it still going due to weather in the bay

Ill let you all know what I hit in a month or two once I can get my system installed and all still trying to get everything I need. Ill be running 3 12" L7 Kickers

this is the kind of post I want to AVOID! Please don't say "I have subs" what does that tell ANYONE list brand/style, amps/power etc...

I have a JL 10w6v2 and a JL 500/1 and sometime soon i will have 1 more of each tryin to go with a custom slot ported box, about to get a Monster 1 farad cap, Got a Alpine 7893 H/U and prolly goin get the JL Audio VR's for the inside, or maybe the MB Q's or Eclipse, most likly stick wit JL's though

and if I do not hit at least 150 db I will drive my car off a cliff !!!

you wont hit 150

hahaha why not ? with 2 10w6v2 and 2 500/1 and a box that is made for max SPL ???

Elevation Execution 15" and PPI PCX1500 amp

148.7

cuz i was to lazy to list what i have now, if your curious, i have pioneer avx-7000cd, pioneer 8000r brain, mb quart dkd 116, mb quart dtc 169, lightning audio 1000.1, alpine flex 4, 2 12" rockford punch hx2, 1 farad digi cap. i havent got this meter yet, im probably expecting 140db

its virtualy impossible to determine what your SPL is based on data. A fellow engineer coworker is working on a simple excel spreadsheet to give you a range. Its still a work in progress but i'll let ya know when we finish it.

y not just get RE XXX or some adire audio brahma, ant
