is the amp rated at 400rms? or you saying you only need 400 because of the sub rating?

I havnt seen a 400rms amp wth 1/0 inputs....

and yes it would be good for future expansions, or additions of more amps.. i have 4ga in my car but i am now running 1/0 for the sub amp i will be putting in... im leaving the 4ga in to power my front stage whenever it happens to go in

the amp is rated at 1000 rms @ 1 ohm. 500 rms @ 4 ohm. my sub is 400 rms.
i`m sure 4 ga is a good wire for that amount of wattage but im just afraid that itll fry the amp because the wire is too small. am i way off on this?

ok well that makes more sense then... the amp is capable of more power so it would be best to do the big cable just because well its better... i thought you were running a 400w amp...

this way you add a second sub later or something with a 1ohm load then you dont have to worry about power... so iyes the big wire would be the best choice.. Its just more difficult to run the 4ga thats all...

ok. this is all i plan on doing right now, with probably no future upgrades. ill always be pulling under 400 rms out of the amp. still a good idea to buy 1/0?thanks.

well its never a bad idea... youd be fine with 4ga but you say now it wont go bigger... but we allsay that in the beginning... if its going in what is your avitar then go 1/0 you wont need to much and its just a better idea...

ok. i know, its probably smarter to go with 1/0 because i can always upgrade later on. However, im coming up college this fall and money is becoming a bigger issue as we speak! So if i can save 40 or 50 bucks id like to do that and go with the 4ga as im in college for the new few yrs and shouldnt be spending money on stereo equipment anyways lol.
I just gotta be 100% that running 4ga to the amp wont burn it out or hurt it at all..

well you dont have to buy the expensive stuff... you can get the big shot for cheap at places like princess auto etc... just get welding cable... and its price is close to that of 4ga from a company like stinger etc... then you have the big wire and its really good wire and you didnt have to spend to much :)

does welding wire have to be insulated or anything?Id rather go with stand ppower wire i think tho just for looks. Ive got some stuff fabbed up for it i wouldnt wanna ruin it with some welding wire in there if u know what i mean haha. I found some 1/0 KLM for 3.25, which isnt too bad, but if 4 ga is 1.75, and its all i need, and wont cause problems i think i`ll go with that..

welding cable is fully insulated and meant for outdoor usage... and it doesnt look bad it just isnt transparent and only comes in black hahahaha... but if you wanna be pretty then get the KLM... welding cable goes for about 1.40/ft or something like that....

ok...well ill check out the welding cable this week. If i dont get that, i`ll get 4 g. this is completly ok for the amp correct?
