I have 2 Rockford Fosgate P2 10's wired up to a sony xm-sd22x amp. Here is a link to specs on the amp.

The problem is that when Im driving after about 30 to 45 minuets the subs will just cut in and out. It will got out for 3-5 seconds then come back in but keep doing this. Its very annoying!!! The sound still plays throught the speakers and the head unit works fine just like it is supposed to. The amp has a fault light to come on if there is a problem and when the subs are going in and out the light dosnt come on. I just got this stuff installed proffesonally about a month ago. The only thing not new is the amp Ive had it for a while but they said it should be fine. And idea what is going on???

 

check your wiring, if you ran the wires under the truck follow the exhaust, and if you ran it through the firewall look at your headers/manifold. That is a loose connection or short (my power wire rubbed my headers in my ford and would short out on right turns haha)

 

I checked every wire and fuse and they are all in perfect condition.

 

you amp might be going out. do have a warranty or a place that could check to see whats wrong with it?

 

subs arent blown? mine cut in and out and turned out they were blown...

 

Thats what Im thinking Im going to take to the place that installed it and get them to check it and see but i wanted to see if anyone had maybe a same problem.

 

hmm check the amp when under stress, run a bass test CD for awhile with them all the way up. The amp should click or heat up pretty good if it is going out, and if it is the subs I think they would always be cutting in and out, not just 30 minutes after warming up

 

if you amp has the power light on its supplying power...

 

yea I would take it in, if they are a good shop they should fix it for free as long as you didn't cause it. They will be able to diagnose the amp/subs being blown pretty quick if thats the problem

 

Theres two lights a blue one fore amp power and a red one for a falt indicator. The blue one stays on even when this is happening but never the falt. I think it may be overhetting to this is where I have it placed
