Circuit City ? I'll keep that opinion to myself.
If all is properly hooked up, Check the ground wire for the amp.
Give it a tug where it is connected to the car chassis, NOT the amp,
if it moves or comes loose thats easy to fix, scrape the paint off the grounding point use a high quality ring terminal and a oversize screw with a star locknut. Also check the wiring in the box.
Subs and boxes are quite heavy. And if it's banging around, I hope you have it in a trunk, they are very lethal projectiles in a hatchback should you have a accident.
My second thought is that you may have dislocated a component , solder joint, or cracked the PC board,
When in doubt see a installer. Good luck Sumthin

SOURCE: 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.

SOURCE: kenwood kac-7204 1000w amp with 12 in sub what

bigger the better my friend. Look at your Peak RMS output, and how long of wire you need. Then you could make the judgment call on how thick or what gauge you need. (2 involved factors power + distance). id say 10 gauge and you would be fine.

SOURCE: My kenwood kac-929 1000w amplifier is not powering my sub

unless you are a technician do not mess with the amplifier.
it takes years of school to learn electronics. unless it is a blown fuse or something simple,you will never fix it.
i did kenwood warranty for 8 years and the amplifiers are difficult to repair.

SOURCE: KAC-9103D hooked up to two 12

I have a Kenwood KAC-9103D hooked up to two 12" KFC 3011. My amp stopped working the other day after it worked fine for about a year the blue light for the fan lights up, the fan runs and the amp runs but the red light flashes on and off and there is no output to the subs. I hooked the amp up to a friends system and it does the same thing. It also makes a tick when the red light flashes. But i have confirmed that its not the wiring. Whats up?

Had similar issues with mine, ended up being that the ground I chose was not a strong enough ground to support the electronic load. maybe try grounding the system to a different location? just a shot in the dark

My Kenwood KAC 5001PS red light comes on and stays on but it still plays how's that possible

most if not all systems require a power source directly linked to the batterys main supply. depending on how your system is installed, you may also have it connected to a Switched Power Source, such as your car radio, that will only turn on when the ignition is switched to on. if im understanding your dilemma correctly, and the light stays on and such - possibly wire the system differently with a switched power source that will disconnect whenever you choose

Kenwood KAC-8103D on and off problem

it sounds like the power wire might be grounding out somewhere that you dont know of it could be by the fuse link so I would say put electrical tape on any exposed wire on the fuse link first if that don't work try change the power wire.

Off and On at mid and high volumes

sounds like you have a problem with your grounding on you amplifier. check for shorts on your amplifier and the place where you have it grounded. (or check the power wire also.)
