Does anyone no more less were the gain .low pass bass bost etc; settings should b at? The same for the 175.4 amp so that there not clipping.. I'm running 2 level 4.. 12" subs. In a ported box tuned to I think 33 or 32hz...if that helps.. I just hooked it up to mess with it & its clipping. . I just put two 6x9 to hear it cuz my MEZZOs still havnt arrived but figured I can set the 2k amp. Any help would b much appreciated! Thanxs
