Question about Kenwood KAC-X401M Car Audio Amplifier

1 Answer

No amp for cd or usb

I just wired the radio up and I have an amp with two subwoofers. The amp will turn on and work fine for the tuner but when I use a cd or plug my ipod in, the amp will not come on. I have read the manual and checked all the wires but still don't know what is wrong.

This is generally caused by using the wrong switched output. If the head unit has both a power antenna control output AND an amp control output, you need to use the amp control output to feed the remote turn-on input on the amp. On head units that have both types of outputs, the power antenna output goes off when you switch from radio to a source that doesn't need the antenna.

Subwoofer works with radio, not with a cd. is this a preference setting? how could i fix this?

Make sure you are using the blue/white wire to turn your amp on. The blue wire is antenna remote turn on and turns off when leaving tuner mode. The blue/white wire is amplifier remote turn on.

I hooked up a Sony deck and new Kenwood 12' subwoofers and amp that came together in a box set in my 95 Jeep Grand Cherokee and when I play the radio the stock car speakers play but the subwoofers are...

their should be a blue and blue white wire on the Sony radio. cut the blue wire and then connect the car side to the blue white wire and tape off the blue wire that is on the radio side.
the blue wire only turns on when the radio is activated. the blue white wire is activated when the radio is turned on.
please rate my solution.

When i have the stereo on radio my amp/subs work fine, but as soon as i switch the mode to USB ( built in ipod connector) it cuts out the power to the amp/subs. It only works on tuner mode (radio) why?

use the blue/white wire (amplifier remote turn on) instead of the blue wire (power antenna remote turn on) to turn your amp on. the power antenna wire shuts off when leaving tuner mode.

I have two ten inch subwoofers hook to my clarion cz200 they work with the tuner but not when listing to aux or usb how do i fix it

Sounds like you have the amplifier for the subwoofer only coming on with the radio. On the back of the Clarion radio, you should have another blue wire, but with a white stripe. This is the correct wire to use for turning on the amplifier. Connect this to the "remote" or "turn on" connector of the amp.

YEs i have a Kenwood X592.And my subwoofers only beat when the tuner is on.when i place a cd or my jump drive in all it does is play the music.the subs dont work

you have the remote amplifier turn on wire hooked up wrong. The power antenna goes off when the radio does... so it will lose power when you put in a cd or go to aux.
install the blue wire labled AMP. or REM.
Problem solved.

Subwoofer in my car works only on tuner

I had the same problem. most radios have a power antenna wire and an amp turn on wire it sounds like your amps are being turned on by the power ant wire that loses power when you put a cd in try swapping the blue with blue and white wire this should solve it

No sub when listening to a cd

you're using the wrong remote output wire. You have it hooked to the power ANTenna wire (blue) which turns off when not using the tuner. You need to use the REM OUT wire (blue w/ white stripe).

Kenwood receiver/sub problem

The amp's remote turn-on wire is probably connected to the blue wire coming from the back of the stereo - this is intended for a power antenna, which is why it only works when listening to the radio. Disconnect it from the blue wire and connect it to the blue/white wire coming from the back of the receiver and you should be good to go.

My amp works on tuner but switches off when i change it to cd

The remote turn-on wire from your amplifier is connected to a blue wire behind the head unit. That's a power antenna activation wire, so the amp only turns on when the tuner is on. Switch it to a blue/white wire from the head unit instead; that should be the amp remote turn-on output.
