I just bought a 2008 F150 supercrew lariat and my subwoofer cuts off and on all the time,when I turn my radio off and back on it comes right back on,it does it about every 10 or 20 minutes whether im driving or just sitting still.Can any body help me fix this problem?

 

How many watts is your amp? It's either you have too small of a power wire or you don't have a good ground. I had the same problem.

 

I really dont know,its the factory stereo and amp,with the factory subwoofer,its sure driving me crazy.

 

If its the factory you might have a short somewhere and it just doesn't connect sometimes like two bare wires rubbing up against each other or something other than that idk what to tell you. Sorry man

 

Does it shut off regardless of how Loud you turn it up? Or does it do it randomly?

 

Best bet is a bad ground

 

It doesnt matter if its loud or low,It seems like it does it more when I first take out driving anfter it does it 4 or 5 times it doesnt do it as often,loud or low..

 

I would think its a bad ground or a bad power connection. Also, could be the amp is going out.

 

I've got the same damn problem! Driving me nuts!! Have you been able to solve this issue? If so, could you say how? I would really appreciate the help.

 

I have the same problem. I have checked all the connections, and used a multi-meter to check power flow. I can't seem to find the problem. I have found the sub will cut out rolling or sitting still, and at high or low volumes. It seems to happen less when the volume is closer to the max. That's just my truck anyway. It's more irritating than anything. The only thing I haven't checked would be the grounds. I don't know exactly where they are. If anyone can figure out what the root problem is that would be amazing. I am considering replacing the entire system to include doors dash and sub.
