noise/earth problem with orion d5000 (quick answers)

[cmorebutt6969]

hello im a noob on the website and have a question for you

i had 2 kenwood amps in the car 1 x comps and 1 x sub, running 4awg power and ground, no problem,

i have just installed a d5000 amp 0awg power and 4awg ground to both term's.

so now i have 1 x d5000 amp for sub(0awg power and 4awg ground) and 1 x kenwood amp for comps(4awg running power and earth)

when i connect the rca cable to the kenny works great but when i use the output rca to connect to d5000 i get the sound of the orion amp fans coming out the speakers.

all grounds are where they was before just added one (not in the same place)

what do you think could be the problem?

Dont know if its the cause of your noise, but your ground wire must always be the same size as the power wire.

idk about all that, but i DO KNOW your ground needs to be as big as the power. it doesnt do any good to run 1/0 power and have 4ga ground. it's a complete circuit, and the 4ga is a bottleneck.

^ This.

By not having the grounds running to the same spot it is more likely to have a ground loop problem.

That amp has dual pos and neg inputs if i remember correctly and it should be 2 4guage pos an neg terminals on it. You need to make sure you have a good solid ground
