it's a ground wire. it goes from the amp directly to bare metal in the car. screw one end into the GND spot on the amp, and the other into some bare metal using a self tapping screw and a drill if you've got one. scrape away any paint/grime whatever so that you can hit bare metal.

naw, unless it touched the power or remote wire input on the amp. that could do some damage.

Ditto UK's comments... Only when the GND wire touches a Pos voltage source, you will get a nasty spark and maybe blow a fuse on that circuit is all.
If GND comes loose off the amp, the amp will not have power and no sound will come out of subs is all.

The amp has power just the subs arnt working i thought they had blown i think i might b the fuse . Thanx for all your help

if the fuse is blown, the amp will not get power. I am all out to help people, I really am. But I am sorry to say that when I have a customer say they are installing something themselfes as long as we can show them the ground, I give them a really really strange look. You have to learn to crawl before you walk, you have to know what/where a good ground is to put in an amp.
I really think you would be better off going to a shop. Starting out in car audio you think that you are just trying to make it sound better/louder/what ever but do not think you can do any real damage. When you start talking power wires(comming loose especially) you can do damage up to and including catching it on fire.

I agree w/ ttocs on this. There could be several reasons why your subs are not working, too many for us to try and trouble shoot on here w/ limited information. The amp would not power up if it was a blown fuse, so there could be a problem w/ the amp, the subs, or even the RCA's......your best bet would be to take it in and get evgerything checked out.
There are a number of problems a lose or disconnected ground can cause. One of the first things you learn in car audio is never connect or install anything w/ the battery still connected, you must eliminate all power in the vehicle. A disonnected ground can cause damage to the amp's inputs, the preouts on the source unit, or both. Personally I would have look at the set-up and hands on trace all possible elements to find the problem......not something an inexperienced person should be attempting themselves.

Well said gents!
Not everybody that comes for help, has adequate skills and knowledge to troubleshoot or even install their own gear. With time spend learning and understanding the steps, many can learn to become proficient. But that takes time and effort.
Lack of specific knowledge is hazzardous to the vehicle, audio system and even the user, if they don't know what they are doing.
