All wolfram finally. Getting rid of the nvx 800.4 if anyone is interested. Returning that POS hybrid cap. The minute I disconnected fuse from battery and voltage began to drop. Reading lo after only 30mins unplugged. What a joke. Was thinking of putting the smartbattery 25ah lithium in it's place, anyone know if these are any good? The wolframs are different shades of silver, errr. Thinking about a third re audio sub. Some car audio candy I thought I'd share.
