the hardest time i had was finding what size my alternator was to get a fuse to replace the one going from the alternator to the battery
as far as grounding go to and audio shop and pick up some new battery post mounts with multiple negative connections and positive connections (they come in packs of both or you can just get the negative one

) connectors just regular eye connectors will work and just find a good spot to ground to and try and make it as short as possible
how is your set up wired now ground locations and wire sizes??
