Question about Kenwood KAC-848 Car Audio Amplifier

Kenwood KAC-848 amp not working

My old trusty Kenwood just went mute as I was driving. The power light comes on, but there's a *pop* coming from the speakers in a steady half-a second interval without any other signal. Also at the exact time I hear the *pop* the power light flickers once. I have no idea what this problem can be, since my grounding is fine (it worked before) and AFAIK I haven't overheated it.

    As i drove for a few seconds my Kenwood amp emitted a popping noise that persisted for a while, as I checked my amp I noticed that the power lights was blinking on and off, I bought a new wiring kit but that didn't help,

Resolder all connections on the mainboard to the transformer and to the speaker jacks. Also check the emitter resitors.

It sounds like the amplifier is going into protection mode. This is generally due to shorted output transistors but can also be caused by shorted wiring. Disconnect all of the speaker wires and signal cables from the amp. If it still does the same thing, confirm that you have adequate voltage across the B+ and ground terminals (at least 11 volts DC). If the votlage acrosss the terminals is OK and the light still flashes with no speakers connected to it, the amplifier is in need of repair.

I have a Kenwood KNR-D558BT with JL amp and speakers, I went to turn it on and lights come on but can't get any sound

You have to isolate the source of the problem..If you have another known good amp throw that in there to see what happens. If no sound also then your head (Kenwood) unit if fubar. If it works then it is your JL amp. Chances are your speakers are good unless you smoked them to death by over driving.!!!!

No sound from my speakers

You didn't mention if you have any external amplifiers, so without more information, I can't help you. Here's a link to the manual for that head unit:

Power amplifier kenwood, power led blinks, no sound

There will be noaudio coming out , if the protection circuits is

sensing a fault or overload , just to protect your precious speaker

from further damage ( or the amp itself ).

These needs servicing.

Amp won't turn back on, all fuses fine, all connections good

that sounds like the amp might have a bad ground.

I have a Kenwood KVT-911DVD in my tahoe. I heard a pop coming from the back of my truck, i have an amp under my back sit. i thought i blew my amp, as luck has it, my transmission went a couple of days...

Do any of the lights on it come on. Have you tried to take it out and connect the red and yellow wire to the battery and the black to the truck frame? This to see of any of the lights come on. Did you try to press the reset button? If you press the button and nothing happens then you may have to send it back to Kenwood for them to reset it.
