So my vehicle's amp recently stopped working. It worked great after I installed it about a year before, so after testing for shorts, burnt out fuses, etc, I decided that the amp had died on me. After getting a new one-and it not working either-I checked the voltage at the end of the power cable where it hooks onto the amp. I get a 12v reading when the ignition is off, but only a 4v reading when it is in the run or aux. position. The in line fuse is good, as well as the battery (just had it checked). Any ideas as to why this is happening? As of this posting, I have NOT tried running a new power cable yet, but that is the next step if nobody has an answer. Thanks.
If the electronics paintings, then it isn't the battery, Hooking up the skill twine the floor does no longer something, there is not any longer a circuit to end, without skill. Even the distant turn twine, having skill, would the two placed the amp into risk-free practices, or pop the fuses...Does it attempt to coach over? or if no longer, does it have a starter solenoid?
sounds you have a loose ground connection.
I had a similar problem a few years ago and simply couldn't make sense of it. I traced the power wire back testing it every couple feet and eventually got to the AGU fuse holder. I had ~14v on the battery side and very little voltage on the amp side. It LOOKED fine, and the fuse was fine, but something weird going on in the fuse holder itself simply wasn't making a good connection. I replaced it and was back up and running. I'm not going to say that's definitely your problem, but it's worth a check,
Try a new power cable, if i were u, I WOULD def. go with 0 guage Memphis wire, which is 95% pure copper. Its very good wire, top quality. Your old wire just burned out cuz it was probably around 10% copper.
