You said you had it to the jack itself? And how long is your ground wire?

 

no i removed the jack from my truck and used the bolts that go directly into the truck body to ground. the ground wire is 4ft long

 

Thats a test probe light. That would work to see if your +12v power source is good though.

 

Why go through the trouble of regrounding your amp, get your test light and check your 3 connections ON the amp. If ground is in question, put the negative test light on the truck body, and see if you then get a light on the 12V sides. It'll take you 30 seconds.

A lot less work, and it will identify if your amplifier is defective, or not recieving the proper power.

 

3 power connections on amp??
am i missing something. 12v power to battery, and remote turn on to fuse... what would the third power source be?

 

Double post...

 

12Volt(high current)
12volt (remote)
Ground (if this is the problem, your tester will not light), then move the lead to the truck body and hope for light - if you get it, reground is necessary.

A multimeter, analog or digital would be much more beneficial, and would also help you determine the "quality" of your connections, but you should be able to do just fine with a test light.

This is also ASSUMING(your description is a little vague) your amp DOES NOT have any indication of power. If you HAVE POWER, but NO SOUND, we need to look elsewhere, like suggested before ground quality, sufficient turn on current, audio inputs, speakers, or defective internals may be the culprit.

 

yes well i have power ON the amp using the test probe thing. and the problem is the indicator light on the amp is not lighting up
