Question about Car Audio & Video
WE'VE BLOWN THE SUB FORCING THE PROTECTIVE LIGHT TO BECOME ILLUMINATE... WHAT OTHER THAN FUSES COULD BE THE ISSUE? WHERE DO WE LOCATE FUSES AND/OR OTHER POSSIBLE ISSUE/S (ANY SUGGESTIONS)??? REALLY APPRECIATE ANY ASSISTANCE..
The first thing to try is to disconnect the sub and all speakers from the amp's output block. The only things that you need connected to the amp are the 12V power, the ground wire, and the remote wire to turn it on. If the protection light comes on with only these three wires connected - your amp has been damaged internally and will either need to be repaired or replaced.

The amp probably has shorted output transistors to eliminate other possible causes, read through the following page. Let me know if you have any other questions.

Overload maybe. If the amp is run at an improper impedence, the amp will shut down. If you are "CLIPPING" speakers / subwoofers the light will blink to indicate a hard clip . Example: 4ohm/2ohm stable amp with 4 ohm subs wired at 1 ohm.

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.

that would be the amp. sorry to say. when a wire crosses over, it sends a shock through the amp, there are a few things to try just to see if you fried the amp. the first thing to try is to move your ground to a different location. second thing to look at would be the fuses. alot of times the fuses will blow at the slightest shock. the amp will still turn on if you have an amp with 2 fuses, it just wont be getting all the power it needs, which could be causing your problem. also, it is worth the hour and a half to mount everything down in your vehicle. you might check the kicker website, because i have herd rumors that kicker offers a lifetime warranty on almost all of their products. best of luck, and i hope you didnt fry your amp.
