SOURCE: Problems With My Jensen 425 Watt Amp

It's normal to see sparks when reinstalling the fuse. But they should only be produced inside the fuse holder when the fuse makes contact with the terminals of the fuse holder.

Did you reinstall the capacitor with the correct polarity? If you installed it backwards, it may have blown out or could be causing other problems.

Did you possibly bridge the connections in the amp when you soldered the camp in?

It's possible that something failed and caused the cap to melt out of the board. The failed component may have caused the fireworks inside the amp.

SOURCE: possible bad alternator?

I went through three alternators before we found a good one for our saturn sl2. Now she has been good for two years. All I did was go back to where we bought it from, they hooked up the alternator to a machine and gave us a new one when it read that it was faulty.

YOUR KILLING YOUR ALTERNATER
that would cost more than a grand to replace.
I advise that you get ur battery tested by AAA or any local maintenece shop.

After 7 yrs of use, it just stopped working


I agree that It could be one of the other reasons listed here.....

But, I had the same problem with a 1,000 watt Kenwood amplifier and it worked like a boss for the whole two years that I had it and then one day the box that I had my subs in somehow came apart and after I changed out boxes the amp quit working. It came on but it wouldn't work anymore except for when I turned it a certain way or sat it against something.. Anyway it ended up being a loose female port plug on the inside where the auxilary cables plug up.

Hope it helps.

Kenwood amp worked fine yesterday when I went to start my jeep I noticed my sub was not working when I looked at the amp the blue light was not on, I looked at all the fuses they looked fine cant figure...


If the light is out, it's not getting power or is in protect mode to prevent further damage. If you have a voltmeter, measure the voltage between GND and 12V (BAT terminal) and also between GND and REM terminal (with the car and radio on).

If neither has voltage, your ground wire has come loose. If the bat terminal has no voltage, your fuse under the hood is blown (they can blow and still look fine sometimes) or your power wire is loose or broken. If the REM terminal has no power, your wire is broke or has come loose from the back of the stereo.

I have a 2000 watt hifonics brutus amp ...it worked fine but 1 day it just stopped working..the power light doest light up but the hifonics led lights are still on...whats the problem?


there is a step up converter inside the amp that likes to come loose from the board. This may be your problem. Otherwise Check all the chips for burns or disconnect

INFINITY AMP PROTECTION LIGHT FLASHING FOR 5 SECONDS


I have an Infinity amp as well, and I was having the same issue for a time. The amp is protecting itself from some sort of overload. It could be the Ohms load on the sub, but I would guess not. Make sure your low pass filter is set to LP and not HP or Flat. Then check the RMS on your subs and match that to the Amp RMS. Once I did all that I found that everything worked fine, for a time. It started doing this again, and I checked the fuse and it was blown badly. It seems that the fuse setup on some of these Infinity amps is not as good as one would hope, because the charge was bridging the gap and frying out my fuses. It was like a spark would jump from one side of the fuse to the other without travelling the fuse itself, and this was causing my protect issues. I pulled the fuse, got a new one of the same rating, but I placed the fuse in with a little piece of rubber in between the 2 contacts, and then connected to the fuse block. I have not had problems since.

Soldering 'Card Cover Open' Switch Closed


I had the same problem after a little plastic trigger thing fell out of the hole above where it says push to eject. After poking around for a while I took the camera apart (remove 7 screws) which made it much easier to see, with a magnifying glass and lamp, what the problem was. A damaged wire that needed to be connected to something. Only the very end of the wire was visible, inside a small white plastic box thing. The plastic box thing eventually fell apart with my attempts to put in bits of wire of varying shapes. When it came loose I was left with a short stiff bit of wire. I took a strand of copper wire (from an old piece of electrical wire), twisted it so I had a small loop at one end, looped it over the end of the stiff bit of wire, and then curved the rest of the wire (about 3 - 4 cm long) so it was resting on a silver piece of metal just below where the white plastic box had been. Put the cover back on and the camera worked. Needless to say, it won't let me know if I've left the cover off, but then it won't work unless the cover is on, so it doesn't seem to matter. Saved about $100.

Amp Trouble


Actually, it's more likely that the problem is on the outside of the amplifier than the inside. Your problem may be caused by a ground wire that's come loose from the grounding point, a defective fuse or corroded connection on the power wire, an overload of the remote input wire, or a problem with the head unit that your amp is connected to. The easiest way to troubleshoot is with a voltmeter. Test the voltage at the amplifier's main power terminal and remote terminal while the meter's black probe is connected to the ground terminal. If you find voltage dropping on one of the terminals, you can focus your attention on that wire.
