Amp Troubles

[Kujotk]

Had a mate inspect the set up i had, he went over the whole car, top to bottom, checked and re connected the head unit from scratch, followed the rca and remote wire to the amp, connected it properly to the battery and capacitor, i double checked it, amp fuses still blew out. Funny thing is ALL 4 fuses blew out, but the 50amp inline power fuse didnt blow... we didnt even have the rca/remote or the sub speaker wires connected so it must have to be a problem with the brand new crappy boss mono block amp.

some vital stats were grounded properly, 14.2 volt was constant (even when starting the car), also recons that the amps were a constant 1.4 amps even when starting the car, i thought you couldn't measure amps but he recons he did and he has seen systems running with peaks of up to 14amps and the (amp) could handle the power. oh i'm talking about power current (amps) aswell as the box (amp) that makes subs work properly lol. also he measured a few other things and said this car with these stats are perfect for safely running a good sytem....

He used to be a professional installer while he was at uni, now he's moved on but still knows his shit... He said the old Luxon amp i had must have just given up after about 5 years of being hammerd and transfered from 4 cars in its life time, and its coincidence that the boss mono block amp that was bought brand new (3 weeks ago) must have been a dud (also saying boss doesn't have the best name for reliablility around and this scenario could be more conceivable). He said if i throw in a known working amp that is more reliable and it still works, then the boss amp is a dud, if a known working amp doesnt work in the car then the car its self is the problem. Seing as the system worked well for a year before the amp broke, how then could the car it self be the problem?

the car is a simple set up, 8 gauge power cable from positive terminal of battery to positive section of capacitor, then the positive section of capacitor terminal to the positive section of the amp.

Negative terminal from capacitor to negative section of amp, and negative section of capacitor grounded to chassi where the battery is actually grounded to.

Also i by passed the capacitor with battery directly being connected to the amp through 8 guage with 50 amp fuse, and the negative from the amp getting grounded to the chassi, same thing happend.

Also i ask for chris roger to throw in what he thinks of the situation coz after reading thousands of posts on here i recon this guy is 99/100 correct if not 100% correct in this field and his imput would be greatly appreciated.

Chhers guys and sorry for the long read

dead amp. I would say that with out looking at it. I would need to have the car in front of me to diagnose it properly.

ALL sorted out, the boss amp was faulty, and my rca cable was shorting so thats why my original amp would turn on but not have any sound through the subs...
