Just wondering if anyone on here has had the problem I'm having. My amp powers up but nothing happens. After about 30 minutes (when it's warmed up) I start to finaly get life in my sub. When that's finaly working it's not working to it's fullest unless I'm stopped at the lights or moving slow.

 

Any ideas?

Either the amp or sub is goosed or there isn't enough power going to the amp.

 

I'd check the power supply, the remote power and the earth first.

 

And test the sub using a battery, not a car battery though.

Place the leads on each terminal and you should see a range of movement, obviously the more power there is, the more movement there will be.

 

Also check the RCA leads.
