I have a kenwood subwoofer, the red light comes on but I am getting no sound, help?!


red light is usually bad like protection mode unless it is supposed to be red. amps are always green and red is protection indicator normally. look it up for your amp and if you bought it used you got ripped off

hi there
The reason for this is the ground is weak to the amp make sure that the post that your ground wire is screwed down to is tight also make sure that is touching bare metal if there is paint on bottom side use wire brush to get the paint off so it is bare metal a weak ground can mess the amp up and make it not work at all hope this helps you have a wonderful day

My subs/amp are not working


when you car is running, it charges the battery somewhat. So the voltage problem is not a problem. The red light means the amp is going into ''Protect Mode". This usually happens when something is wrong with the amp. Usually the amp is getting hot. Check all of you connectiong and check the final impedance of the subs. Make sure the amp can handle the impedance of the subs. If you need anymore help, message me.

Red Light


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

Kenwood kac 859 amp


hi, note that if you are not using the proper gauge b+ and gnd cable with this amp then the current available at the amp wont be sufficint to keep amp on. also try using this amp while vehicle is idling. if this doesnt work then disconnect all spks from amp and check if red lite stops flashing. if it doesnt stop flashing then amp has internal fault. if lite stays on brite then proceed to check each spk load impedance, then reconnect each spk individually. the minute red lite starts flashing it will give you a clue that the channel or spk load is faulty. cheers

Light stays red


I do belive this amplifer has a red light when it is on... I know my Kenwood does. I suggest checking all your wireing between your amp and your speakers, check the impediance between your positive and negative terminals on your leads to the subs.
