March 25, 2008Your gain is how much preamp level the amp allow's into it's input .Having the gain wide open is not the answer ,that can lead to noise in your system .
You have subsonic filter's which are nothing more than a high pass filter at a very low frequency .They can be helpful in ported system's ,where freqencies below the port tuning can cause damage to your subwoofer's.
You probably have hi and low pass filter's to .You can stop the low frequencies from damaging your mid bass driver's and tweeter's,plus create a low pass cutoff to your woofer's
March 25, 2008btw I would have posted which amp you are referring to ,maybe it may have helped someone here describe it's control's
March 26, 2008Here is a detailed description I gave to you a couple of weeks ago on how to set the gain.
As far as high and low pass filters(crossovers), you want to use high pass for your main(front) speakers, and low pass for subs. What frequency you set the crossovers at is a matter of taste to an extent. Usually in the area of 70-80hz for high pass, and 100 hz for low pass is a good place to start. But you also want to crossover to match up with the rest of your system. You do not want any part of the frequency band not covered.
Bass boost and such should be set where they sound the best to you.
March 26, 2008hey 69camaro396 do you know exactly what sounds change from each of the subsonic filter do
March 26, 2008you shouldn't notice anything with the subsonic filter on ,although I have noticed a decrease in bass in certain system's.
Most are designed to cut off frequencies below 20 herz that you don't really want going to your sub's anyway's,your just wasting power.
Although some setup's are adjustable ,like PG's base cube you can track the port's cut off frequency.
I suspect your's are fixed
