that car only got 166db. ONLY u say lol yeh only. A Lancer Evo 8 at MUK last year reached 170.4db
and u could feel the bass from about 10 metres away hehe!
That lancer evo 8 reading was utter balls then. Seriously, I hate it when people dont measure systems properly.
The meter mic should be placed on the passanger side of the car, stuck to the windscreen (not in the boot, footwell, seat, anywhere else).
Also, a Termlab USB microphone setup needs to be used, as this is now the world SPL standard (for EMMA, IASCA, etc etc).
166dB is LOUD, and if they can only just achieve that with an 'extreme' classed car (i.e. a car where steel and concrete has been used), then an Evo will no way reach 4dB higher than this.
The Fin's (currently number 1 in the world) hold the world record at around 177dB, now that is loud. But thats through using special transmission line boxes and lots of mathematical calculation, plus 1000's of hours worth of testing.
A system by the Fin's that is similar to what is running in the Evo hits around 160-165dB (Street B/Super Street B), but thats running with a few batteries, over 20kwrms of power alone, and for a quick 3 second burp at the loudest calculated frequency.
I therefore conclude that 170.4dB is balls :laugh:
I'm in the high 130's atm, and I'll need a bigger box and better sub to push that any higher......
Oh and with many cars you can feel the bass 10m away, I know the Primera at JAE a couple of years back used a JL W7 with around 1.5kwrms, and that thing was extremely impressive. I hope to show off my new system in my next car to a few people, and show them what real bass is like
