87accord Posted July 16, 2009 Author Report Share Posted July 16, 2009 300 amps on each amp so 600 + 80 for the kenwood i think sorry at work dont have the amps here Quote new system in the works (3) DC lvl 4xls 15's (one of three are here) (2) DD z1 (done) old kenwood four ch 4 runs of 2/0 (done) ? 200 amp alt may two ??

87accord Posted July 17, 2009 Author Report Share Posted July 17, 2009 (edited) ok i think i might have found my answer here it goes since i am running 2/0 i should have a 400 amp fuse up front then another 400amp fuse in the rear right before the battery and a 300amp fuse for each amp since my amps are dual power and ground inputs i should have a 150 amp fuse on each input totaling 300amps right? so this would be the lay out alt----[200amp fuse]------battery------[400 amp fuse]------[400ampfuse]--battery---[300amp fuse]--amp Edited July 17, 2009 by 87accord Quote new system in the works (3) DC lvl 4xls 15's (one of three are here) (2) DD z1 (done) old kenwood four ch 4 runs of 2/0 (done) ? 200 amp alt may two ??

The whole point of fusing that lead is to prevent fires. I'd suggest a 250a fuse max for 2ga wire.

87accord Posted July 17, 2009 Author Report Share Posted July 17, 2009 (edited) the wire i have is 00awg i though it was 2/0 but i might be wrong ok just looked it up and yes it is 2/0awg wire or 00 not 2awg so would i be correct with using a 300 amp fuse since that is all i can find Edited July 17, 2009 by 87accord Quote new system in the works (3) DC lvl 4xls 15's (one of three are here) (2) DD z1 (done) old kenwood four ch 4 runs of 2/0 (done) ? 200 amp alt may two ??

SQMonte Posted July 17, 2009 Report Share Posted July 17, 2009 the wire i have is 00awg i though it was 2/0 but i might be wrongbefore going any further, find out what size your wire is Quote Alpine CDA-117...Memphis 16-X03 CDT Audio SQA-4100...SEAS Prestige H1396...Crescendo MP-6 Soundstream Rubicon 1.2500d...Digital Designs 3512f Link to comment Share on other sites More sharing options...
