Hello everybody. This is Gus from Greece. I own a kia picanto 2007 and i want your help. Fisrt of all, forgive if i make mistakes, i can't speak enhlish fluency ..

Well, i put on my car two amplifiers. The first one is a 4channel blaunpunkt gta 480 which is connected with my subwoofer signat onyx 112 and plays only the sub..

The other amplifier is a 2channel axton C400, or something like that (i can't remember well) and this one is connected with focal 130A1 speakers. I want to tell me how i should setup my 4 channel amplifier so that it will not be damaged or my subwoofer won't be damaged too.

So, i want you to tell me how to set the input sensitivity, the bass boost, the frequences etc. Please tell me rates. For example, the dbs goes from 0-12, the frequency from 50Hz-250Hz and the gain from 0.3V-8V.. Which are the "right" rates?

These are gta's 480 technical details:
