Re: Whats this?

Hi, might be several reasons: 1) to loud, the amp might be auto protecting; 2) one of your 4 speakers has a developed an intermittent problem, either open or coil grounding to magnet; 3) the pigtail (wire from terminal to coil) might be occasionally touching the metal body of the speaker (just carefully bend/move the pigtail out of the way); 4)impedance mismatch (speaker ohms too low for the amp) or too many speakers connected (check/replace or lessen); or 5) it is possible that the amp is not getting enough power from the battery/electrical system or a loose ground somewhere (although a bit unlikely). Hope this be of some help. Please let us know how things turn up. Cheers.

What does it mean when the red IND PROTECT light is on? my subs cut in and out, mostly out with the occasional hard hit popping up in the middle of a song. Whats wrong?

You've got the gain to high and the amplifier is clipping the sound frequency causing it to distort. Possible problems are you have a bad speaker(s) and the reading is below 4 ohms. Each of the 4 channels can only take 4ohms. If your bridging 2 speakers to this amp you have to also make sure you are only bridging 4ohms anything lower will cause the amp to overheat. Dont put 2 speakers in parallel on one channel or you will definitely have more problems.

When just wblue wire is connected red light comes on

This sounds normal. The light comes on when there is 12v supplied to the blue wire (remote input). Need more details.

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.

No sound, and a Immediat Red Light turns on everytime..whats it mean, and how can i fix it..

If it goes into protect mode with no speaker wires connected to the amp, it sounds like the audio output transistors have shorted. If that's the case, they would have to be replaced. It would require troubleshooting to find the shorted parts. You'd then have to disassemble the amp, desolder the defective parts and install the new parts. The following page provides the basic information needed to repair the amp.

Power light

This could be a DC offset condition. Check you manual for what this means. Or other condition. First Disconnect the Subs and try it. If it still goes red then disconnect the RCA's and try it again. If the Led continues to go red after the click then the Amp is hosed. The Click you hear is an internal relay that cuts the subs in after a dely so you do not get the turn on THUMP of the radio at your subs.

Stop putting out sound to subs

Ok This is a two channel High Current amp. It is stable to one ohm. If the Subs are single voice coil at two ohms the they have to be wired in Parallel that means (Red +) (Black -) are connected to the + and - of another sub and then the (RED +) (Black -) from both go to one output channel of the amp. You pair the other two in the same fashion on the other output channel. If you are getting no output (sound) at all first check if the amplifier is going into protect. (Usually indicated by a red led on the unit. If it is connect only one Sub to each output and see if the protect LED goes out. If it does then you should have sound at the subs. If not check that you have the sub output enabled on the HU some head units do not come with the sub output enabled on the HU. If every thig is enabled, with only one sub connected to each output and the protect LED is not on then your amp is probably blown and needs repair. Nice thing is that MA has a great warrenty policy. Check and make sure the protect LED is off. If it is on you probably have the SUBS wired wrong
