Ok, so as a temporary amp I have a kenwood 9152d mono amp. For some reason it has two imputs for speakers, I thought monos only had one? You can see it kind of in this picture... I have a dual 4 ohm sub wired to 2 ohms, using the first positive and the first negative, is this right? Also I was told that bridging it like that would drop the impedance to 1 ohm? One more question, for some reason I have to turn the gain like 3/4 the way up before I start seeing any power from it, and it's not clipping. This doesn't make sense to me, as I have a pioneer premier 680mp that's supposed to be giving me 4 volt preouts, and the Nine2 I'm using for components is good to go at like 1/3 gain level... Is this kenwood just a crappy amp?
