cool, thanks for the quick response from someone who knows. thats how it should be. now, for the second part of my question. instead of using a Y-splitter, can i plug my signal into say the right input. then build a very short RCA cable and jump from the right output back to the left input? i wont be using any of the onboard processing in the amp if that matters. on a side note, i love these amps! i had a dual 4 sub wired for 2ohms that i was powering with a small class-D amp which supposedly was capable of 400watts at 2ohms. ran that for about a week. got curious, pulled the sub, swapped the wiring out for series connections (8ohms). pulled the class-D and installed the 100.2 bridged on the 8ohm load. it walked all over the supposedly 400watt class-D. WOOT! (irrelevent, but just wanted to share my expirience) now these two 100.2s i have are going to be delegated to midbass duty and im going to start looking for a 1500D.
