skittlesRgood Posted November 19, 2010 Report Share Posted November 19, 2010 what is the voltage at the back battery? what size is your wire? If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

n8ball2013 Posted November 19, 2010 Report Share Posted November 19, 2010 OFC is capable of 300 amps of current carry. You have a 270 amp alternator as well that is probably underrated. Are you at idle when you are testing this drop? If so you are probably only getting about 130 amps produced. a real 3kw amp should pull about 350 amps of current. how old are your batts in the reaer THERE IS NO BUILD LOG! 1998 Chevy Silverado ext cab Alpine CDA-9887 4 Team Fi 15s 2 Ampere Audio TFE 8.0 2 Ampere Audio 150.4 3 Digital Designs CS6.5 component sets Dual Mechman 370XP Elite alternators inbound! 8 XS Power d3400 6 XS power d680 Second Skin Stinger Tsunami Wiring Sky High A Real Voltmeter not a piece of shit stinger.
