If your speakers are wired for an impedance below 4 ohms mono or 2 ohms stereo, that would make it shut off. If you have a speaker wire shorted to ground, it would also cause the amp to go into protection.

 

If the speakers are not the problem, it may be shutting down because the voltage at the amp is dropping too low.

My amp isblowing fuses


make sure the amp is not crossed, and grounded good. if it continue to blow fuses, you might have a bad transistor, i recently had the same problem. check it out.

Fuse keeps blowing every time ignition is turned on


you probably have a shorted part inside of the amplifier.

Every time i turn my amp on it blows the fuse what do u think is wrong with it?


Hello! Is this a new installation? If so re-check your wiring... If not, tell me what the year, make, and model of the vehicle...Also identify which fuse is blowing; vehicle fuse or in-line amp fuse?

I have a kenwood kac-7202 and it keeps blowing the in-line fuse


Are all the wires hooked in right? On the bare parts of the wires, are there any 2 wires touching? Most importantly, do you have the correct fuse for the stereo?

look at the Z [impedance] specs for the amp. Look at the Z for the speakers. You may eventually have to wire them in a series-parallel config or risk blowing your output transistors.

Due to the utilization of so many drivers, your power demands are limited. The more drivers you utilize, the more volume loss. Bass response requires a lot of power (W) in which to drive.

Do not worry about paper or polyprop/carbonate structures... focus on your impedance issue or risk frying the output transistors in the long run [thermal runaway].

Nope it's not a high-to-low level converter problem, it's most likely a problem with one of two things. 1) either you've blown the output stage in the amplifier, or 2) you've hooked up your subs wrong and your amp is seeing to low of an impedance. The amp is supposed to be 1ohm stable, but we had the same problem. When the indicator light goes red it means that the amp has gone into protection mode, now you have to figure out why. If something in the amp goes bad or just disconnects from the board it will cause power protection mode. If you fry something on the board because you are running the amp to hard or at the wrong impedance it will go into thermal protection mode, however there's no simple way to figure out which has happened.

Have you tried hooking up some different subs to see if the problem remains? try this. If the problem no longer happens then you know it's your subs, if it does still happen then you'll know it's an internal problem.

Years ago I had a Kenwood KAC-821; long story short, I melted the main power wire right off of the board, everytime I turned the system up the amp would shut down.

Take you amp to an authorized dealer and have them bench test it for you.

Let me know what you find out.

Keep blowing fuses


Check for shorts to ground in the speaker wiring, the speakers themselves, total Impedance, especially woofers. Proper size power and ground wire and all connections. Use a Ohmmeter or find a friend with one that knows how to use it, If all else fails RMA .
Good luck, sumthin
