Question about Infinity Reference 7541a Car Audio Amplifier
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.
