[QUOTE="shredder2, post: 8675892, member: 674047"] In my case space available was a serious concern, I still might go bigger eventually for the nextsecondary battery if I wire to .5 like I probably will someday. But I just watch voltage and if it's above 12.5v I'm close. Of course I'd love a steady 14v but $ and space is a factor. I just wanted some stronger voltage as before the lil' Northstar I could drop voltage under 10v pretty easily. That lasted a week or so due to procrastination but once I got motivated to resize the enclosure it got done. For my usage at this point it's sufficient, a full volume burp pulls it just over or at resting voltage as is... on music it's in the mid 13v range mostly so for now I'm kinda finding the system limits until the NEXT upgrade... :*******: Fuses?.. breakers?.. I fuse once up front close to the starting agm and before the secondary battery and that's it. I've never fused amps that don't already have them... never had a problem either. And as long as the rear battery is close to the amp I won't bother in back. That said... depending on how it's setup would affect my decision regarding rear fusing (layout... etc). I have it wired as 2 batteries parallel with a 250A alt... nothing fancy here. Just lots of attention... paid to grounds up front and rear (all doubled-up). [/QUOTE]
