got my sub and amp all installed and its powered up because a light is coming up on the amp but the sub isnt working for some reason. I've got my mate to have a look at it who is an electrician and he cant understand why its not working... but hes confused because on the amp the Protection/Power light is on but its red, and he thinks it should be greeen, hes checked all my wiring and says everything looks right! can anyone understand whats going on?

earthing.

at the min its earthed to a screw what should i earth it too? the earth wire is only about a foot long if that

to a screw? where abouts is you are screw

i find to get read of protection just take all power from it remote power earth and speakers then re attach all sometimes works for me at work...

Could be a supply or earth issue. If you forgot to put the supply fuse in, the amp might power up in protection mode through the remote wire.

If you are earthing through a screw, you need to consider the current than an amp needs to power up.

Did you clean the metal behind the screw to create a proper earth. is it a big enough screw, bearing in mind the thickness of the power lead.

may be a stupid question but i always think start with the basics, is the gain turned up n not turned so its 0 as this would mean there is little or singal going to the sub

ps dont mean to be paronizing just know I've missed things like fuses n mute buttons before.

problem solved, the earth is fixed to a bolt type thing and it was fitted loose so I've tighted it up
