My buddy gave me a 10 inch sub and an amp the other day. So I put it in my car.wired it up and everything. It was working fine for like 3 days. Yesterday I got into my car to drive to work and the sub kept cutting in and out. I was like wtf. So This morning I looked at it thinking it was a loose connection to the sub. Nope, that wasnt it. I checked the Ground, It was good. I check the power line and fuse, it was good. I checked the amp fuse and it was good. I also reconnected the remote wire thinking that it might of had a bad connection. Still the amp cuts out. I had another amp here at my house so I decided to hook it up and see if it was a shitty amp. The old amp had the same problem. Any suggestions here fellas. Im stuck and dont know much about this kind of stuff. I looked the light on the amp and it goes on and fades out while the music is playing. I think it might be the battery???
