Setting up a sub/amp - gain & frequency controls

[feenster99]

Hi folks,
I've just installed a Fli Trap Active 12" sub/amp in my car (http://www.fliaudio.co.uk/index.asp...-frequency.html&sidemore=s-flitrapactive.html)

On the back of it, there are "Gain" and "Frequency" dials - can anyone give me a tip as to the best way to set these up (short of just turning them until it sounds alright!)? I guess the "Gain" should be set somewhere in the middle as I don't want the sub to be thrashed.

What would you good folk recommend to a person setting up his first sub/amp?

Cheers,
Matt

Thanks for the advice. On this particular active sub, there are no markings on the frequency as can be seen in this PDF: http://www.fliaudio.co.uk/downloads/FLI Loaded 200 Amp Manual.pdf

It mentions it to have a "40-250Hz Variable 12dB crossover" - I presume then that I set the Frequency to about 9 o'clock? Is it that the lower the frequency value, the less bass is produced or the other way around?
