kaigoss69 & Squidly, I just tested your theory,,, and it didnt work for me. But it could be my setup.

I reverted back the underseat polarity to normal (+to+, -to-). Re-calibrated the system and played some tracks that overlapped both the lo's and mid's. I could definitely feel the sub imaging coming from the trunk. Before I wasn't able to differentiate the front stage and the sub.

Reverted the polarity and re-calibrated. All back to normal. I can't differentiate the front stage and sub.

Is there an easy way to identify if my wiring is correct for underseat. Cable I used has marking for positive and negative terminals, however without removing the underseat woofer trim I can't be sure if I have the properly connected the the correct terminal. I did this over an year ago.

Thanks

Having said that, it is still good to experiment. In my car, for example, I'm running a 3-way active front, and despite auto-T/A, I had to put the left tweeter in reverse polarity for it to sound good. In the end, your ears are the ultimate judge, not the algorithm in the processor.
