Using Two Subwoofers with Two 2-Channel Amplifiers.


I am considering using two Subwoofers with two 2-channel Amplifiers using the speaker level inputs and outputs on the Subwoofers.  Each Amplifier is currently connected to identical pairs of Speakers.  Is it better to connect so that there is a dedicated Subwoofer for each channel (Left channels of both Amplifiers wired "through" one Subwoofer, and both right channels through the other), or dedicate each Subwoofer to an Amplifier so that L/R channels of each Amplifier go to a Subwoofer?

This is for a vintage system that I am using for music only.  I'd be happy to supply equipment details if that matters.  Thanks!

@stevermanjohnson question about you're dual JL sub's?

Are you using them AND the external high pass filter before the signal hit's your amp's.

I've heard pros and con's of external high pass filters in stereo set ups (JL says yes, REL says no, PS Audi Paul says no).

JL also discourages high level connections in favor of line connections (REL and Paul disagree).

My last question is, how would everyone recommend wiring dual stereo subwoofers with mono block amplifiers (each amp with 4 speaker posts).

Option A. Running a wire from each speaker post of both the right and left amplifier to the right and left subwoofer?

Example: Right amp has two positive wire and two negative wires going to the the right subwoofers two negative and two positive high level connection points.

 Option B. Running only one positive and one negative wire off the right amplifiers speaker posts to only the right high level connections of the right subwoofer (leaving the left channel positive and negative subwoofer high level connections open).

Example: Right amp has only two wires, one positive and one negative, off one set of its speaker posts going to only the right subwoofers right channel positive and negative high levels connections.

My thinking is if each right and left amp has four posts, and each right and left sub has four wire connections, then I should connect them all (right amp to right sub etc) rather the just two of the four high level connections on the subwoofer.

Anyone car to comment how the high level connect dual stereo subwoofers in a dual mono block stereo set up?

Thanks
