Question about Alpine Car Audio & Video
I recently installed a 15 sub in the back of my car when i finally managed to get hold of an amp to power it i got my friend who has some idea what he is doing to help me to set it up. we connected everything up and tested it but it didnt work, we tried everything until we finally realised he had connected the live power cable to the negative terminal o n the battery so we rectified this and the amp worked fine powering the sub nicely, then the next day i went to start my car and the battery was dead, so i charged for about 15 mins got the car started and carried on, i left my house went out for a few hours got back to my car and the battery was dead.. again! so i tried to create a better earth point for the amp and once i had done so i tired the amp again and the amp appeared to power but made no sound so i gave up disconnected the amp and speaker and took them out of my car and went out, once i got back to my car my battery had died once again! so i decided to at this point disconnect the power inverter i was using 2 run a PS3 which had been connected to my car for a few weeks perfectly fine and had not caused a problem and afterwards my car seemed to work as normal, i have recently attempted to try the amp again and it once again appeared to power up but made no sound and i realised at this stage that the fuse in the wire connecting to the battery had blown quite spectacularly although i do not know at what point it had blown. It was also in fact the power on cable from my head unit that was powering the amp. can anyone help me figure out why the amp has been killing my battery and why the fuse has gone???? i got the amp free off of a friend and all of the cables and necessary equipment to run it from him under the promise that it had all worked fine in his car for a long time and should have been fine when he gave it to me but as a result i have no warranty and could not easily get it repaired if it does have a fault. i also wonder whether the fuse went when the amp was connected to the wrong battery terminal although i am assured it shouldnt have and i also wonder if this error could have caused damage to another component or my car????
It should not have affected anything unless the amp gets too hot due to being bridged or the ground and a power source touched each other which would have sparked and put the some amps in protection mode unless it has a fuseable link then it will blow the fuse such as the 12v battery or the power on wire which is blue and is called the (remote wire).
