[QUOTE="forbidden, post: 801679, member: 552189"] A cap does not create power, it stores and uses it. In this case it is a really bad idea. There are very few instances where they are beneficial. A second battery in the back is a bad idea. First it must be secured properly or it can take your head off, second it produces noxious odours that must, by law, be vented to the outside of the car (an exception is a gel-cell type), third it is another drain on a small alternator and will destroy the primary battery if it is not isolated. If you want more play time with the engine not running, a second battery and proper isolation of it is a must, if it for use primarily with the engine running, a good battery up front and proper power and ground by means of the BIG3 (or BIG4) is a must as well.
