Question

Ok, my friend is running a Hifonics Zeus ZX-6000 for his component amp right now. It worked perfect before and then it was re-installed and it started cutting out. Now everything was re-installed at GT audio, very clean install btw, but the amp still doesnt work. Now the amp will work fine for a bit but then it will start cutting out, it doesnt go into protection it just loses power. If you push the ground wire in and hold it there it will stay on but otherwise the amp starts to cut out. Any ideas what could be the problem? I have opened up the back of the amp and it the ground is connected to the board still and everything looks fine internally. Is there something I could use that would be more solid than the wire, like an apadter that I could connect the wire to and then input that into the ground location?

check your grounding spot... seems like you just answered your own question.... I believe those hifonics amps use set screw terminals... if so check how long the exposed wire is... it may not be making full contact since the jacket is preventing it to go in any further into the terminal...

if its a spade type input im sure they would have used the proper spade connectors... id definately check the ground again...

I'm pretty sure its not the grounding location because it has been moved from the last install to this new install. Yes they do use screw type terminals, im also thinking it may not be making contact, but what can I do to fix it other than extending the wire?

yeah its ed's amp, I was thinking of doing that tinning of the wire, but it was too cold and in the middle of a parking lot so I couldnt yesterday. I may have to entend the ground wire because it is kinda tight, so ill extend it and then tin the tip and hopefully that works out.

thats weird how the amp keeps doing that, does it happen all the time or intermitent?

Maybe a solder connection iniside on the board is loose or borken, if you try the ground fix and it still happens.

How come everything was reinstalled? did ed finally get a custom trunk done?

It's sorta like the amp will stay on and play perfect but then after a bit of time with the sub playin the connection becomes loose and you have to push on the ground wire and it goes back to playing properly.

From what I could see on the top of the board everything looked fine, although the loose connection could be on the bottom? When I have time ill get the ground wire extended, how do you recommend doing this? If the problem still occurs than i guess we'll have to open the amp up and take out the board and see if its a problem there.

Everything was re-installed because he didnt like how the amps were on the seats with all the wires showing and he wanted more space. So he got a custom wheel well enclosure/false floor built and the amps are on either side of the trunk on some amp racks. Everything was cleaned up and it looks really nice. Just have a few loose ends to fix up and it'll be done.

soon hopefully, he has that new digital camera so im sure they will show up sometime, might have to go to a meet to see it though.

Any ideas on extending the ground wire? Can I just solder a piece of wire to the existing one and tape that up?

you can extend the ground wire by splicing the 2 pieces of wire together and soldering them, or buying a wire splice and putting heat shrink wrap over it

the wire butt connector comes in 2 forms, crimp and set screw im pretty sure

either should do, but soldering then wrapping with tap and shrink should be best electrically wise and strength
