Got a sub and amp hooked up today and it sounded great. When I got it home I noticed when I would turn the car on I would get a solid bass note from the sub for 10-15 secs and then it would stop. The same thing would happen at random times during the song also. When I would open the car door it would stop.

So I brought it back to the installation place and he fixed it but now I can't control the sub from the head unit, the sub also doesn't sound as good. Before I brought it back up there the gain was only up 1/4 of the way and now it's turned all the way up and doesn't sound as good.

Wish I had more knowledge about audio. Anyone have and idea what's going on?

 

Me thinks I figured it out. I didn't unplug the mic thingy above the rear light in the back seat. When I went back with the problem the guy ran the LOC off my door speaker and called it a day, no wonder it sounded about 1/2 the power when he rigged it for the fix.

I will go back tomorrow and have him run the LOC off the sub signal again and see if all is good.

Thanks rossv1

 

looks like you found it! that installer is crap.

 

Yup, got the loc moved today, unhooked the mic G2G!
