??What Gauge Wire Will I Need??? nearly 5k RMS
Hey again. just need to double check what size wire i will need to run my sound system in my Vx sedan...my system as folows..sorry if this is confusing...here goes
2x Fusion NV-AM25001 Monoblock amps run at .5ohm (well over 2k RMS each)218amps max current each amp..(up untill tomorow the amp has been run at 2ohm with my old subs but when i get the soundstreams in there it will be at .5ohm)
2x Soundstream trantular T4 15's (1000 RMS each)
1x fusion 4ch amp for splits all round (800 RMS total)
So all up thats nearly 5k RMS in the boot....
At the moment all i have power wire wise running ALL THAT is 1 pissy little 4gauge wire split 3 ways in the boot to the 3 amps... It sounds awsome as is but i know the wire is WAY to small for all that...would bigger wire make an audible diffrence???
So my question is what would be ideal gauge for all that? I was thinking 0 gauge wire to the boot split in to 2 2g for the monoblocks and just keep the 4g for the 4ch amp....??
Also i have a 120A fuse at the battrey wich will also be upgraided to the biggest i can buy but i would have thought being that its only 120A shouldent it blow with all that current draw?? Amps are only at 2ohm ATM but when i get the soundstreams in there tomorow it will be down to .5ohm each...then it might blow?
Again sorry if it is confusing but just wanted to get the right wire size for when i put my new soundstream subs in tomorow...Thanx again...
Im no wiz but I can garuntee that thicker wire will def make an improvement and probly increase ur max decibel response :P

^^I did say it was confusing...dont pick!
thing is it sounds so damm good now with 4G wire, the window flexes so much its about to break..tomorow when the soundstreams go in and down to .5ohm im pretty sure it will crack, I just cant see it getting any louder than it is...im just a bit shocked that the 4G does that good its hard to think that the 0G could do any better. thats where the question started..just seeing what is by far recomended..
Thanks for your replys.
Thanx nick92, that helps heaps!
Think ill go with duel 0G from battrey..

I'm not going to read this, but if 5kwrms 0awg should suffice. Make sure you run it properly, distribute the power properly, upgrade your earths/alternator charge appropriately.

There Fusions , 4awg will be fine ...

For a start the amps are 1.7k W RMS at 1 ohm. Running them at lower impedance will cause problems. Your audio install fails on so many levels it's not funny just an observation. In saying that run 0 guage to a distro block then 4 gauge to the amps.

I cant wait for the
"Hey Guys My Amp Caught Fire"
Thread, driving them at too low an impedance.
Also if you were truly running 5k wRMS you would be running more thn 1 single 0 gauge run, You would have a battery bank, and a nice 180+ amp alternator...
Ah well, The kids got to dream...

1.7k rms @1ohm is at 12v, Amps have been bench tested to do around 2250Wrms from memory at 1ohm 14.4v, And they can be run at .5ohm, Its been done, and playing daily to,..8 months+ and still going great!. I have had the 2x 0gauge wire to the mono amps installed, Installed the soundstreams running on .5ohm and sound's Great with no problems, Local audio guy installed the 0 gauge thrugh and recomended a deep cycle in the boot wich i will get done very soon...
Over the years i have run things at stupidly low impedances + doin other stupid stuff just experementing yet never even nearly had a fire....oh and am yet to hear of anyone that set there car on fire that way... But anyway job is done now and all sounds great..thanx to the ones who helped out with my original question...
0ga to a second battery in the boot.
or, about 4 runs of 0ga to the single deep cycle/heavy duty battery at the front, and never play the system at full power for music, because the battery will never keep up.
