You could switch to a optima deep cycle battery. Also improves on batt life

I highly reccomend 5-90's 5 main wire upgrade. Made a noticeable difference in my stock lighting alone. Have you seen the engine ground? It is a 1/2" wide strap, it works but could be much more. The alternatpr NAPA sells for my 99 puts out 120 amp.
