Hm - a little hazy since I never sold Kenwood back then but I think they actually sold woofers with a 'feedback coil' on them so you could have a true servo setup with their gear - similar to the Linear Power and other systems.
For those who need to know - a servo setup uses some form of feedback to the amp such as a second voicecoil or an accelerometer to compare what the cone is doing to what the amp said to do and then corrects for it. Theoretically you get perfect bass reproduction.

that and there online manuel isnt very helpful,
"When maximum power is required, the KAC-X401M Mono Power Amplifier is ready to deliver 300 watts X 1 channel to drive sub-woofer systems to the max. With a maximum rated power of 1200 watts X 1, this MOSFET driven amp includes the Bass Management System for 6 or 12 dB of "High-Q" bass enhancement, variable low-pass and band-pass electronic crossovers, selectable infrasonic filtering to eliminate unwanted woofer movement, and Sigma Drive circuitry for accurate bass. Speaker protection and quiet turn-on features are also included in this competition quality monster amp."
or ill say da hell with it and hoock up the jl 500/1

well, either the amp does not work without this special woofer, or its pooched, i hoocked it up, at to the wiring diagram i found on the kenwood web site to one of the woofers it was previously connected to, very very very very very week, i meen my little ppi rated at 120 to a 4ohm bridge hits harder
so i go to the hatch to investigate, all my connections were 100%, but funny thing when i hit pause i could hear noise coming from the woofer, new to me cause my instale was quiet befor i unistaled the gear i had in there last summer (jl 500/1 2 ultimate max 12s ina big ported box)
threw the jl back in the hatch, pounds like a ****, so does anyone know what i was doing wrong, or is the amp pooched like i suspect.
