I just recently installed my subs in my new car. It worked for about 2 weeks but i noticed after long drives the subs would stop hitting from time to time. Yesterday the sub completely shut off. The amp is still powered and not showing any weird lights. So i started doing research.
first thing i read was how the coil in the sub could be ruined but thats not the case. I tested the sub on an inside system and it seemed to work just fine. So back to research. Now the install part of it could have something to do with the system but i'm thinking maybe a battery issue? I don't have blinking light or anything interior but i noticed my trunk light blinks now when the sub decides to hit.
I was playing with the settings on the amp and turned the gain to about 30% and turned the EQ to 50%. The sub started hitting for about 1 song.
I am wondering if my amp is clipping? The other issue that has crossed my mind is the connection inside the box/sub. I have read that they come loss or something and ppl solider them back in. Also i am going to add a capacitor tomorrow and see if its a battery power issue.
Anyone have any ideas to diagnose the issue further?
