sub getting no power

[before-i-forget]

my sub has suddenly stopped working last night, a few days ago i had the battery out to test fit an air filter which i didnt like anyway and it was fine then but then stopped working as i got into my car last night, the power lead is attached to the battery so i know it's connected but the light on the sub is not on so it's not recieving power. Any ideas on what could be wrong/ need to check?
Thank you

Fuse?

 

[before-i-forget]

On the power cable just before it gets to the battery there is a little black box with a fuse in it, I guess it could be that one, by looking at it can you tell if its blown? All the other electrics work fine so I gather its not any other fuse?

well check the fuse on that, its easy to see if the fuse has gone as the little metal connector inside the fuse will have snapped inside it. If not, check the fuse on your amplifier connected to the sub, if its not that, check the rca cable/remote cable and if not them.. could be the amp isnt working!

ground wire?

Cheers guys I'll have a good look around Monday morning as working all day tomorrow.

Had a look yesterday and the fuse in the engine bay is fine. There are two on the back of the amp which i can't seem to remove to check if they have blown or not, i've pulled on them quite hard but they don't seem to want to move, am i being a bit thick or do i need a special tool to remove them.
This is the sub in question

Should be a tool in your fuse box inside passenger door. Bright orange grabber.

i would recheck the power cable fuse not for it being blown to see if its making a connection i had a glass fuse in my car before and it separated inside but looked like fine when you gave it a quick once over

you should be able to see the fuse on the amps just by looking at the top of them or on either side

Make sure the connection on the battery is tight, have had it in the past where I havernt tighted it enough and it affected the amps. other than that, as said check the fuses and earth.

Definitely check your ground (earth) cable if that is not dead tight and a good connection then this can cause problems as you are experiencing.

Is there any power light at all? Usually it will be red if theres power going to it but theres somethign wrong with the ground/remote. It will then be green if the circuit is complete, well thats what mine does anyway.

Make sure you grounded your earth on a metal surface (file down for good connection). Also make sure your remote is connected to your head unit and amp.

I had the same problem with mine a few days ago, so I went an baught a really good quality wiring kit an it started working again! I had checked everything before hand though an there was nothing obvious I even took my whole sub and amp apart! Lol
