hey guys, im kinda new here
i been watching the forums for quite a while, however only juz joined recently

Got a Quick Question for ya's

im juz wondering on an approximate SPL for my car, i got a 83' Ford KB laser (yes its a POS ), a Hertz HS300 12" sub in the HBX30 box (the pre-constructed one from hertz). A Kicker KX600.4 amp bridged, Hertz HSK165 6" splits and the JVC KD-S785 (entry level mp3 deck) headunit

juz want an approximation at what sorta SPL i can look at getting for this setup

Thx heaps

~138 is my guess. oh wait your in QLD, about 143

hehe, wish to explain why it would be diff ??

Andu is taking a stab at the fact that certain QLD people havent been able to match or better their scores measured in QLD when tested on NSW meters..

Well known fact some meters up here read higher than the official dB Drag meter. but we have also come to the conclusion, that the Maroochy Car Sound meter, reads approximately the same as the Doran Pro audio meter in Sydney. So scores posted on these meter's are our best chance at comparing...

Anyways, that box is a bandpass design, not sure on how its tuned though... if that laser is a hatch? i would guesstimate about 135-142dB...

I assume rear channels are bridged to the sub....
Possibly with that box and placement possibly 140ish

arh okies, kewls

well im hopeing that my system will be tuned well, as i am often at Custom Image at browns plains (this is where i bought all my stuff ) and i am hopeing they will tune it accordingly for me

and yes the rear channels will bridged for my sub, as i am not using any rear speakers for my setup

one other thing, does anyone from here go to the maroochy car sound SPL days (such as the one at the start of this month)?

EDIT: soz didnt know swearing was monitored , my bad hehe

somewhere between 120 and 150

nar im guessing it'll be somewhere between 135 and 132, mainly cus of the sub and power.
if you fed huge power into it u may get high 130's

ok, the custom image meter is the one that has caused problems in the past, it clearly reads higher then any other meter in the state and some members have claimed they hit this score using that meter and that how the whole thing about 'QLD meters are wrong etc' started...

if you really wanna know how loud your system is goto the test n tune night that we are holding in the next month. the meter used there will be 'real'

by the way, we (QLD CAA) had about a dozen cars enter the MCS sound off at the start of this month...

ok fair enuff, well i will come to the test n tune Anyone got an exact date for the test n tune yet??

And juz for interest sakes, how much higher does the custom image meter read??

[ February 11, 2003, 02:02: Message edited by: Groomy ]

hmm, about 3db higher then MCS meter... and about 5db higher then the meter used at fb...

far out, thats a fair way off, so when dave does check the SPL my car will do, should i juz take 3-4dB off it?

if you take about 3db off his meter you will get scores similar to the MCS and northfield meter...

take about 5-6db off the score using dave's meter and then you'll be close to the GCCS meter that is being used for the test n tune...

k, and bodyjar, we got a date on the test n tune??

cos maybe u guys could give me some assistance in tuning it proply too on the day if ya willing to give a newbie some help

always willing to help looks like the test n tune will be put back a month due to lots of comps in march... it looks like april is the goer.

Yep, definately going to have to be in April sometime...

We'll all give you help whenever you need it, just ask!

well im still paying off the rest of the amp
then i gotta spend $300ish on security system, then gotta find another $100ish for wiring

so it wont be completled for another couple weeks upto a month. But then im sure i will have many questions and queries on how to make it sound even sweeter than it will

id guess about 135db
