POssibly Blown amp? Please help

Hey all, Thanks in Advanced for any help on this issue. This is what i'm using Infinity 7541A 4 Channel Amp Infinity 692.7i 6X9 Infinity CS6010 6 1/2 component speakers I purchased all these off ebay and unfortunately the amp was sold as it though it was working the last time he has used it, sold his car blah blah blah. Well after i hooked everything up i am getting on the amp a solid clip and protect LED the power LED is off, the unit is grounded to the trunk with a new hole drilled and that shouldn't be a problem i am getting consistent 12.5 when the car is on accessory and a 14.5 when running. Its difficult for me to diagnosis the problem because the first thing that comes to mind is that i got screwed/scammed. So ill leave it to you guys. Incase it might help the wiring setup is 4ga to distribution blocks for dual amp setup and then 8ga currently to the amp. Remote wire is hooked up to the antenna blue/white on the back of the head unit. I am seriously stuck please tell me the amp isnt fried *i did happen to smell the unit when i got it to make sure it wasn't fried and it seemed okay. thanks again

If you have the amp hooked up with all connections properly connected plus have sufficient voltage then if it still goes in the protect mode then your amp is no good. I would recomend you check your speakers and make sure there are no problems there.
That being said other than over/under voltage and/or short in your speaker connections again, your amp is no good. After checking all this let me know. I would recommend you unhook speakers and try and turn on amp. It is fine to turn on with no speakers. Amp has resistors inside for this and sees a load even if no speaker connections. let me know if still not working cause i'll buy amp from you if you want to sale.

Amp 7541a amp was working fine, Took it out of one


REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL GOES INTO PROTECTION AND YOU HAVE VERIFIED THAT THE POSITIVE AND ESPECIALLY THE GROUND CONNECTIONS, ALONG WITH THE REMOTE CONNECTIONS ARE 100%, THEN THE AMPLIFIER WILL NEED TO BE SERVICED. KEEP IN MIND, THAT DURING THE INITIAL TURN ON OF THE AMPLIFIER, THEY SOMETIMES WILL ILLUMINATE THE PROTECTION LIGHT WHILE STABILIZING THE POWER SUPPLY AND OUTPUTS, BUT AFTER THAT THEY SHOULD SHOW NORMAL POWER UP. IF YOU GET IT TO POWER UP FINE, THEN RECONNECT THE SPEAKERS AND IF STILL OK, THE RECONNECT THE RCA'S. IF IT IS STILL POWERED UP, THEN START TO TURN UP THE MUSIC. IF IT IS STILL POWERED UP AND NO MUSIC, THEN CHECK THAT YOU DEFINITELY HAVE A PROPER SIGNAL COMING FROM THE RADIO. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

I have an Infinity 530a 5 channel amp. new


May be the problem is on the sound you are using is not a 5 channel coded sound or check in the menu´s of the amp if the rear channel´s have sufficient db output, check the connections, check if you amp. is not working only as simple stereo (menus also)

Hope this helps

INFINITY AMP PROTECTION LIGHT FLASHING


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.

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.

Infinity Reference 7541a protect & Clip lights come on


Hello pianopeter, I have the same amp with the same problem but only when the crossover mode switch on the front channel is set to low pass or high pass. Have'nt fixed that yet cause when I got the amp and put power to it the clip and protect lights would flash back and forth. I turned out to have 2 bad output transistors on the right front channel, I replaced them and amp works great now. Then when I was doing final testing I switched the crossover mode switch to lowpass and your problem occured. I do believe the problem is in the removable board which controls the controls the crossover and input to a point. Try moving the crossover mode switch to flat on both front and rear and let me know if amp works fine that way. I'll be working on this problem soon but would like to know if your problem changes if you move the switch to flat. Please leave me a message as soon as you find out cause this will aid in the process of me fixing problem. I am an electronics tech and buy and fix broken amps all the time so I have a really good knowledge of car amp repair. Once again let me know ASAP, Thanks
