    few quick questions on wire upgrade

    Ok I got some cash and think i need to upgrade my power wire to 1/0 guage from 4 guage. I got a 1200watt amp and it's getting 4 guage wire. I'm getting pretty bad voltage drops at stop lights when the engine isn't revving. The 4 guage i have has to run the length of my huge arse suburban so i think the 1/0 is needed. How much would it help with voltage drops. And also would it make a difference if i didn't upgrade the big 3 but just the power wire. What kind of fuse holder and fuse would i need for this new 1/0 wire. Right now i have a 60 amp fuse.

    I would do that, and upgrade your big three. Make sure you use the same guage big 3 as your power wire. If i had the money that is, may be wrong, but thats me.

    the fact is that you have a struggling electrical system and need some type of upgrades. big 3 is necessary possibly a new battery and H.O. Alternator in the future as wel.

    Even at 100% efficiency(impossible), it would still require a 100A fuse. Are you sure your not giving us a "peak" spec.

    Re: few quick questions on wire upgrade

    i never really looked, but yeah i just went down and checked and there is definitely a 60A fuse in the fuse holder connected to the power wire, so obviously i will have to replace it. And i'm positive my amp is running @ 1 ohm to my speaker and has been this way for over a year. It's 1200 watts rms. i'll probably be upgrading my wire to 1/0, but the only thing i'm concerned about is doing the big 3. I can't seem to locate all 3 wires and it looks difficult. So what fuse should i replace it with???
