I kept the APJ-1's and just bypassed the stock Phat EQ board. They sound great! Now I believe the bass is worth more than it's worth. But I read their wiring diagram upside-down and so the volumes were back ward, I had to turn it up to turn it down. And tone was backwards, treble was really bass. So I re-did it ONE MORE TIME! But by now the pots are scratchy.
. I hope the spray cleaner works, other wise it back to ground floor and getting new 100k audi pots and doing it all over again. I Yi Yi Yi YI.
