you dont want to use the RMS when calculating for wire length, you want to use the total maximum.

what would happen if my amp ground was bigger than my power input? this truck is what ive been able to get so far

 

good question... i currently have 4 awg kicker flex from front battery to rear seats dist block split to to my cadence xneth 120.2 (30a fuse) and sundown 1000.1d (90a fuse) i was thinking of running industrial 2 awg coper power cable and than 4 awg splitting to my 2 amps after dist block and i was planning to use a 1/0 awg power wire to ground the sundown amp... What do you guys think?

 

grrr... feedback would be great

 

If you already got 4 gauge power, why rip it out and go through the hassle just for the next size up? Two gauge main power with 4 gauge from the distro block would work. But if it was me, I'd just run all 1/0 wire and know I'm good and even have room to add bigger power if I choose to. I'm pulling my 4 gauge for some 1/0 gauge and I wouldn't bother for 2 gauge. It would help but not enough to justify buying the new cable and installing it.

I got a 32 foot roll of 1/0 gauge Monster cable for about 60 bucks if I remember right. That was enough to do my big 3, amp ground and power and still have a pinch left over. Got 10 ring terminals for about $22 also. (Don't know why those damn things are so expensive nowadays.) I know you already have done your big 3 but you could get a shorter section for your amps wiring for not much. Just my opinion.

 

Hey guys. Is there actually a difference between ground cable and power cable. eBay has 20ft ground or 20ft power. Both the same price just different colour. If I want black and its ground can I still use it for power?

 

Wire Gauge question:
What size wire should I use inside the car for hook-up of ALARM leads... Door switches, dome light hook-up, The wires that come with it, look pretty small. 18G. or 20G. maybe? I don't think they are long enough as they are, so I want to get more.
ALSO: What gauge wire would be used for 250 watt MAX RMS 6 x 9's?

THANKS!

 

for your alarm 18-14 would be just fine and as far as your speakers i ran 12g to all my factory speaker locals it makes a big diffrance

 

well this is awkward, i just ran new wires for my fog lights out front and made a home made fuse box essentialy, i used 12 gauge to go from +on fuse box to my box and then ran 16 to my lights and ground, weirder is that its bigger than the wire the lights came with, is this fine or should i be worried looking to redo?
