Strange problem

[nickb1994]

Hi guys,

I have come into a problem today after hooking up a second amp to run my fusion splits.

The setup:

JVC speakers in front doors- Powered Pioneer head unit

1000w Pioneer subwoofer - Powered by 600w SSL amp (I do not currently have the subwoofer RCA's plugged into the Head unit because i need and RCA splitter)

180 watt fusion splits - Powered by 250w Sony Xplod amp

When playing music I get distortion from the JVC's running off the Head Unit. This is only since installing the second amp, they used to sound great. When i set fade to front and the splits are not running there is no distortion but as soon as i slowly set the fade back the distortion gets worse. It is more so on the left side where i get the distortion. (the side i ran the RCA's)

Could the Head Unit not be grounded properly? What else could it be?

Thanks

Nick

I also get a humming/buzzing sound when the engine is running

rca's running next to power wire?

Does the hum/buzz get louder as the rpms go up??

the Rca's are on the opposite side to the power and remote wire and i am prety sure the sound buzz is constant and does not change with the revs. The sound stays the same volume no matter what level my sound is on. If the sound level is low it is worse, but when its higher it is harder to hear.

I grounded both the amps on the same point is that okay?
