Question about Kenwood KAC-9152D Car Audio Amplifier

1 Answer

Sub power comes on consistently for about a second and thuds

I have 2 12's (Kickers) attached to my 1000 watt kenwood class D amp.

The amp comes on and then thuds then goes back off
It does this every 3 seconds consistantly.

The head unit has no effect on the volume of the subs.

Is my amp going out?
or do i just have a bad ground?
Can you PLEASE help

    no there is only one light on the amp that is the triangular power light.

    could any settings on my head unit be affecting the subs like this?

    its as if the amp gets power for a second and then shuts off.
    But it DOES NOT go along with the music just consistently hits one time then shuts off.

    is this a symptom of the amp going out?

    have you removed the wiring for the subs to see if the problem goes away?

    Also verified +12VDC at the remote wire and power wire?

Kicker 12L5 blew from a kicker zx750.1


MY BEST GUESS FROM WHAT YOU HAVE SAID IS THAT THE BOX WAS TO SMALL. BUT YOU ARE OVERPOWERING THE SUB RUNNING IT AT 2 OHMS ON A 750 WATT AMP WITH A SUB THAT IS ONLY RATED FOR 600. NO MATTER HOW FAR YOU TURN YOUR SETTINGS DOWN, YOUR STILL PUSHING TO MUCH POWER FOR THE SUB TO HANDLE. IT IS ONLY RATED 600 WATTS FOR A REASON. ESPECIALLY IF YOU LISTEN TO MUSIC THAT HAS A REAL LOW END AND THEN A HARD HIT. REMEMBER A HARD HIT WILL SPIKE YOUR AMPS OUTPUT THEREFORE PUSHING MORE WATTAGE TO THE SUB.

I was given a subwoofer and box but do not know where to go from here in terms of hooking it up in my car. It is a Rockford fosgate punch p112s4.


First youll need an amp. Depending on what size the sub is a 500 watt rms amp can hold up to about a 300 watt kicker. If your looking for something bigger u can get a 1000 watt amp and hook up two 300 watt kickers. To hook up the amp youll need a car amp power cable, power control cable, speaker wire, amd a car amp ground wire. They usually sell kits that run aboyt 40 bucks. The power cable goes to the batter as well as the ground cable. The power control cable goes to the back of the head unit. (You will kost likely need a more modern headunit if urs is stock). Once this is done put the sub in the box (i recomend super glue because metal nails take away from the bass). Put the speaker wire to the speaker positive on left negative on right. Same with the amp. And now ur bumpin ;)

So I have the first kickers that came out the 15 will a 800 watt amp push um without eather blowin out


If you are referring to the Kicker L5 solo-baric subwoofer, then an 800 watt peak amp will not blow even one of those subs. The L5 is capable of handling 1000 watts peak and 500 wrms. An 800 watt peak amp will usually have around 400 wrms. Underpowering the subwoofer will not hurt the amp or the sub(s).

Hello gonenutz14,

It depends on how you define the "best way". Driving each sub with a separate 750 watt amp will result in about 50 percent more power than having them share the output from a single 1000 watt amp. But with 2 amps, there's more wiring issues to contend with and the adjustments are more complex. The 2 750 watt amps will cost more than a single 1000. Plus if the 1000 watt amp is stable to 1 ohm, the power difference will actually be less than 50 percent because of the lower impedance. But if the 750 watt amps are also stable to 1 ohm and their outputs can be combined, we're back to 2 being better than 1.

I'd say that the simplest, most economical way is to use a single amp. If maximum power to the subs is the highest priority, and cost and wiring is not an issue, then 2 is better.

Hope this helps.

Amp Turns off after 30 seconds of song play.


Check your ground and make sure it is grounded to metal in your car with no paint. Also, make sure you are running 4 gauge power wire. Another possible cause could be that the ohm load is too low on the amp. Also, if your car battery drops below 10v it will send the amp into protection.

Kickers dont beat like they should


try to check and clean the wiring as clean as possible to avoid messing up on your connection. Check the polarity of you subs to yuor amp if you have it connected on the outher way around it would not give you a good result. check the polarity this will solve your problem. Over powering your sub will fry it easily try to tune it a 10" sub wont give you a 15" performance..

Adjusting wattage on kenwood kac 9103 class D mono amp


That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

Kenwood KAC-8401 light goes from blue to red when turned on


Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.
