[QUOTE="zako, post: 8149895, member: 629735"] I will trust you on what you read in the manual since I traded my P900.4 for a P1000.1 last year. I guess, you need to use BP for the LPF. This effectively forces you to have a subsonic filter. Set the HP end of the crossovers to the lowest setting. I believe, 20Hz is the lowest you can go on subsonic. This is one of shortcomings of this amplifier, but 20Hz subsonic filter shouldn't get on the way of most people IMHO. Alternatively, switch to full, and use the low pass crossover on the head unit if you have one. [/QUOTE]
