20 Most Recent Kenwood KAC-7252 Car Audio Amplifier Questions & Answers

that means you probably have a shorted speaker wire, a bad speaker or the amp itself is bad, try disconnecting the speakers one at a time and see if it turns on or not. if the red light stays on with no speakers hooked up it means the amp is bad

You can replace that with an auxillary fan 12V input

dose the amp play hook it up

First of all, how hard are you running them. And what system, wattage, and amp do you have. If you have a 2 or more channel amp, and you are bridging it. STOP, doing so does add power to the subs, but it also can add power that the subs cannot handle, and an amount of heat the amp cannot handle. So your amp could be over heating... good luck

it is most definately a power issue your amp is cutting out due to over juicing (assuming your amp is solely hooked up to your subs and your deck is powering hi's low's mid's) as a safety precaution amp will turn off whenever your cars alternator start putting out more than 9-11 I would suggest taking a voltmeter to your car battery to see what it is at while your idling as its difficult to due while driving and adding a couple to account for the added juice from alternator running at higher speeds if it seems like it would be in the 9-11 range you may need a new alternator or battery

why are you in stereo for subs? mono all the way.

could be a bad earth

check the ohms on the subs if its single 2 ohm make sure you dont bridge it avoid 1 ohm unless the amp is class d duel 2s make 4 or 1 depending on if you series on paralel them duel 4s make 2 ohms or 8 you want to make a duel 4ohm 2ohm and put one on each chanel email me for better exp.

Did you hook up the remote turn on from your head unit?

yes u have got to havr your remote wire from your radio runing to your amp

Check amp switches

If it only does it when bridged, the ohm load may be too low.

Is it blowing the fuse on the amp or the one near the battery?

genrally kenwood amps are power hungry amps so after playing for a while if it doesnt get the amount of amperage to make it work it will shut down cus you car cant charge the battery long enough for the use of that amp so my idea is try a farad capacitor and see if that helps good luck .......tk
