Well most (good) amps all have subsonic phasing high pass low pass filtering etc....huh yeah i could use some free crap but its not my amp its my friends and he is out of town and left me with his vehicle to install everything so im not really familiar with all his equipment and manuals so thats why i was askin
Mostly likely if the amp you bought only has 1 knob, (gain)
you got your self a POS
