Question about Car Audio & Video
I hooked up my sub to an amp and had it working for several days. It stopped working and i noticed that the ground wire no longer sparked when it touched metal, i stripped it down away and it worked again. About a week later, i got the same problem but this time when i stripped the wire down, it didn't help. I got a 4k watt amp and a 15" Eclipse. The amp turns on but there is no sound from the sub
It sounds as though either the sub or amp is blown. When an amp blows quite often the light will still light, but the internals are trashed. The only surefire way to tell whats going on is to use a Digital Multi-meter to check the impedance of the sub, and the voltage at the amp. You can get a multimeter as cheap as $10 at most autoparts stores, Radioshack, Sears, etc...
Also, always post brand names and model numbers, because more info equals more help.
