[QUOTE="PaulD, post: 4654778, member: 589636"] The reason SQ guys like myself use the chassis as a ground is that running a seperate wire to the battery for ground just gives the ground for the amps a different resistance to ground and may cause a ground loop. This will give you an alternator whine that will be very difficult to get rid of. If you are running a LOT of power for SPL, you may find it necessary to run a bunch of runs of large wire to the battey for ground. [/QUOTE]
