akrja_07 Posted April 10, 2011 Report Posted April 10, 2011 What size fuse would I use in between my battery and a 160 alternator? This is just a cheap eBay alternator for now. Hopefully my headlights will quit dimming at least. 2001 Chevy Silverado Ext. cab - Kenwood KIV-BT901 - 2x 12" DC Audio level 3 m2D1 in 4.2 cuft. @29Hz. - DC Audio 2.0k - Alpine Type-X components - US Amps USA-4300x - XS Power D4700 - Bosch 145a alternator
hdorre Posted April 10, 2011 Report Posted April 10, 2011 The alternator size determines wire size, and wire size determines fuse size. What size wire will be ran?

akrja_07 Posted April 10, 2011 Author Report Posted April 10, 2011 Well, 1800 watts RMS amp is what I am fixing to upgrade to, so I was thinking 0 gauge...? 2001 Chevy Silverado Ext. cab - Kenwood KIV-BT901 - 2x 12" DC Audio level 3 m2D1 in 4.2 cuft. @29Hz. - DC Audio 2.0k - Alpine Type-X components - US Amps USA-4300x - XS Power D4700 - Bosch 145a alternator
akrja_07 Posted April 11, 2011 Author Report Posted April 11, 2011 I just saw the sticky... So if the alternator is only 160 amps, I shouldn't use 0 gauge? I plan to go ahead and do the "big 3" when I install this alternator also. In this vehicle, I don't plan or ever going beyond 2000 RMS. Basically my question now is Should I do 4 gauge w/125, or 2 gauge w/ 200? Here is a copy and paste from the sticky. Keep in mind please new alternator and big 3 at the same time, if that even matters. 4 gauge: ~140 amperes Class D (~70% efficiency) - <1400 watts Class A/B (~50% efficiency) - <1000 watts 2 gauge: ~220 amperes Class D (~70% efficiency) - <2200 watts Class A/B (~50% efficiency) - <1500 watts 1/0 gauge: ~350 amperes Class D (~70% efficiency) - <3500 watts Class A/B (~50% efficiency) - <2500 watts And for the fuse size 0 awg 325 amps 1 awg 250 amps 2 awg 200 amps 4 awg 125 amps 2001 Chevy Silverado Ext. cab - Kenwood KIV-BT901 - 2x 12" DC Audio level 3 m2D1 in 4.2 cuft. @29Hz. - DC Audio 2.0k - Alpine Type-X components - US Amps USA-4300x - XS Power D4700 - Bosch 145a alternator
hdorre Posted April 11, 2011 Report Posted April 11, 2011 I would just do 1/0 with the 250-300a fuse. 4 gauge is too small. Who even makes true 2awg wire? If you can get true 2ga, then do that. It'll probably be cheaper and just as effective.

akrja_07 Posted April 11, 2011 Author Report Posted April 11, 2011 Well, I can get 2 gauge... But would rather just use 0 if it's possible, which you just said it is so... thanks man. 2001 Chevy Silverado Ext. cab - Kenwood KIV-BT901 - 2x 12" DC Audio level 3 m2D1 in 4.2 cuft. @29Hz. - DC Audio 2.0k - Alpine Type-X components - US Amps USA-4300x - XS Power D4700 - Bosch 145a alternator
