Hello Tony.

The noise I'm having is probably from the alternator.
It's a whine from the speakers that is variable when I rev. up
the engine. (It is a diesel engine so I don't think it's anything
from the ignition system. I don't know this, but so I've been told.)


This is what I've done so far. If you look at the drawing it will
be easier to understand. (I hope.)


PowerSupply:
I've run a thick (4gauge) plus and minus wire from the battery. There is
a fuse on the plus wire in the enigneroom.
(there is a fuse on the plus to the empeg and all other units as well)
The wires are run under the drivers seat where it is split 4-ways into some thinner
wires. (8 gauge) Then the wires are drawn into the two amps, empeg and
elextronic x-over.

SignalPath:
I'm using both front and rear iutputs from the Empeg.
(Blue front, purple rear) They're are left/right, but I didn't
bother drawing it.
These are fed into the three way electronic x-over. This is
set up to split the signal into my preference for front/back.
I've connected the supplied earthlead on the AMP. for SUB.
This was the only place I could put it without a lot of funny
noises.

The gain on the amps. are not max'ex, so I can barely hear
the 'computer' sound from the Empeg, but as I said earlier
I have this alternator whine. (I think).
