Microphone? Don't you mean test device? Radio Shack used to sell one that measured the db. I'm sure you can search on google.

they sell an at the dash SPL meter.
It's $399.00

The radio shack one only measures to 120dB, and it's more designed for tuning than for mobile audio SPL use.
the Audiocontrol unit measures to 160+dB

oh, in case you're unaware, 160dB is 4 orders of magnitude greater than 120dB.
every 10dB doubles the audible volume, and takes approximately ten times the amount of power to achieve.
that's a huge difference between the meters.

Holy cow, $399? Maybe you should rent the device for a day and go nuts measuring... :-)
