I hate to ask but does your head have 3 pre-outs? if it does and one is dedicated to a sub freq you should run another RCA, I run a five channel amp and will have to do the same thing to get my rears running right when I switch to a four channel for front/rear speakers and a mono-block amp for my sub.
a sub doesnt require as clean a signal to sound good. granted it will sound better with clean signal, but if you have to do it this way then run the y off the rear, and try and find a good splitter, i had problems splitting with y's from radio shack. they would cut in and out sometimes, aweful.
what head unit is this??
