wait a minute, base audio rear deck signals, i remember this being high passed at x hz. is CleanSweep able to convert the signal to full range after it's filtered by the HU?
if the impending answer is "no", would this mean that we should forget about having fade?
if the rear deck signal is indeed high passed, let's just say at 120hz, what should be stopping me from grabbing the rear channels into high level inputs of a small 2 channel amp to power my coaxials? (since i prob shouldn't be pushing the 4" coaxes much below that anyways) fade would be retained in this case. is the rear signal as screwy as the front ones from the factory HU in addition to being high passed?
or let's say that i hook up the rears to CL441DSP to the JL XD600/6 in 4-channel input mode. would the XD merge F/R signal & distribute to all 6 channels? making it possible to get full sound & retain the fade function?
i apologize if any of this sound like crazy talk.
