Positive to positive, negative to a very good solid ground. There's no real need to re-wire the amp.

If you hook it up in series that will make the batteries a 24 volt system. You can still hook them up that way but will need a convertor sperate the 2nd battery so that it will be 12 volt out but still get trickle charged from your cars alternator. This is not something for a amatuer to try to do, take to a legitiment car audio shop and ask them for pricing. they will know exactly what I am telling you. If not done by a professional you can really srew things up on your car...but its the best way to have a 2nd battery for high power use sound systems but still keep it charged at all times... good luck
