ModernDayHero07 Posted December 2, 2013 Report Share Posted December 2, 2013 I've read through a bunch of related posts, but I can't seem to find a clear-cut answer. What size of fuse do I need at each end of the 1/0 wire connecting the starter battery to my supplemental battery in the trunk (positive to positive)?More details:- Running ~2000W RMS for audio system, but only 1600W is running off of the supplemental battery; the other 400W is running off of the starter.- Stock starter battery; CRESCENDO LOGIC F-31HP AGM POWERCELL; stock alternator (but planing on getting a 270 alternator from DC)- 2007 Ford Fusion- The run (+ to +) is 20ft long (running underneath car [all proper precautions have been taken to protect the wire]) of NVX XW0BL20 (http://www.sonicelectronix.com/item_46862_NVX-XW0BL20.html)I am guessing I will need a 150A fuse near each battery for the run... but I don't know for sure..... and I want to know for sure. Even if I'd guess correctly I'd be forever paranoid of the day that my fire catches on fire or something horrible....SO, what size of fuse do I need????

hdorre Posted December 2, 2013 Report Share Posted December 2, 2013 I gauge my fuse size based on the wire I run.

ModernDayHero07 Posted December 2, 2013 Author Report Share Posted December 2, 2013 Ok, so then based on the wire I am using what fuse would you use? Link to comment Share on other sites More sharing options...
hdorre Posted December 2, 2013 Report Share Posted December 2, 2013 Is all your wiring NVX 0 gauge? Even their website doesn't say how much current the wire carries over a certain distance. I would email them and ask. All their site says about power is: Ideal for high-powered systems of over 1000 wattId ask On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...
Soccerballzs Posted December 2, 2013 Report Share Posted December 2, 2013 Depends on output of alternator also. Does that have ecoboost motor?

ModernDayHero07 Posted December 2, 2013 Author Report Share Posted December 2, 2013 Also, I would change out that stock battery for an agm. I've been thinking about it, but I didn't think it mattered too much. But I guess it sounds like I should, so I guess I will... eventually. Depends on output of alternator also. Does that have ecotech motor? They have issues with high output alternator. Here is the alternator I'm thinking of getting: https://www.dcpowerinc.com/fit/2007~Ford~Fusion~2.3L-I4-Duratec/11272-270-xp.html Link to comment Share on other sites More sharing options...
