I recently ordered a new CD/MP3 Receiver (Kenwood KDC-X659) to replace the very cheap and basic Aiwa I am currently using.

My empeg is getting its constant power directly from the battery's positive terminal, since I had power issues when it was wired through the Honda's harness. I plan to do this with both the empeg and the new Kenwood, as well as send the ground wires from both units to the negative terminal on the battery.

My question is, when I go back into the dash of my 98 Civic, what would be the best way to go about using the negative battery terminals for constant power and ground? Should I merge the wires and run a single wire each (one for power, one for ground, say 12AWG) to the terminals or should I run separate wires for each unit all the way to the terminals?

Any input would be appreciated.
