Ill be doing my Honda CRV in 4 ga later in the week.Ive even ran a Kinetic 600 in the rear already.Very suffecient for my needs.Though 0 ga isnt much more expensive than 4 ga taking into consideration.If planning to run more power of over 1200 watts, Id recommend 0 ga all day long, but as we all know, anything is much better that that cheasy 8/10 ga wiring.Im running 2-old school Autotek Mean Machines 66@2ohms on each Kicker CVR,@1.6cu ft @34htz ported, and will be installing a set of Cadence Mids/6.5, and a set of kicker KS25 tweeters in place of my Polk DB6.5 up front, and have Massive 6.5 mids in rear that will be powered by an Old school SStream 4ch 204,.So 4ga should be just fine for my big 3.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
