i have a kenwood excelon kac-x401m sitting on my work bench,
was wondering what the sigma servo thing was on the same side as the speaker out puts

 

it should be labeled right above the sigma outputs.....i use to have one of those amps but cant remember what side they were on

 

ok so how do i connect this thing to a regular woofer?

 

well what the hell then, im going to try it anyhow

 

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.

 

tried it with the sima thingy on the same coil, and then agen not connected

the web site has a diagram where the sigma thing is connected to an active coil
