Subs only get loud if I fade and balance to one speaker

Subs are quiet when fader and balance are centered, then get way louder when I balance and fade to one speaker.

It sounds like you are connected to the wrong pre-outs. Just a guess.

I am running Audison apf8.9 fully active to front and rear components. Then the sub preout to a Audison apf1d to 2 subs. Just weird the subs get at least 3 times louder when I fade and balance to any of the 4 speakers.

It's got to be a setting in the headunit somewhere. That would be my guess.

Are you using the OEM radio? If yes, how are you spliced into it?

Stock head unit. Spliced from back of radio into 8.9 speaker level inputs

Was a car specific harness used where you only had to match color coded wires? If no, then there may have been a polarity issue during splicing. Recheck the work to rule it out.

switch the phase on your sub

We don't have enough info, but I'm pretty sure you got something out of phase. When you fade to one side or the other the phase issue disappears.
