**Perrosky** · 01-02-2007, 01:58 PM

May be tomorrow I will install my I don't have Alot of experience with this but I got one 10ga wire with an 20a fuse just runing from the battery to my trunk just for the opus 250w and I got another for my 4ch amp and mono amp. the only thing that I'm gonna mix between my amps and the opus is the ground and I am thinking about put another ground just for the opus.

3 yellow wires they go to the + wire that comes from the battery.
3 blacks wires they go to the ground that I have in the trunk.

If I'm mistaken plz some body tell me before I frie my opus

Unless you are using a distribution block, you should avoid grounding multiple devices to the same point. It's a quick way to get a ground loop. You also want to keep your ground point as close to the device as possible.

my amps are grounded together via the distribution black. the ground for my computer is grounded separately from the amps.

Actually this is not correct. You are more likely to get ground loops when you have multiple grounding points. The best thing is to have everything grounded at one point.

I'm using a dell optiplex 240

I just installed my opus, connect all the wires, put the fuse and all that then when I connect the negative to my car battery the psu turn on and the computer amps to. PROBLEM THE KEY WAS NOT IN THE CAR.

I USE MY TESTER TO SE IF I PUT THE WRONG CABLE TO THE ACC WIRE, BUT THE WIRE THAT I'M USING IS THE RIGHT ONE. :S

any body have a clue of what's happening? I may take a picture of the connection today. and post ith

The ACC wire is the only thing i can think of. Did you test directly to the power supply where the acc line connected or where you tapped the line?
