Hifonics BXi 1606 and 4 gauge?

I have 4 gauge welding cable in my car, is that too small to handle about 1000 watts from this amp?

I really dont want to have to buy 0 gauge if i dont have too.

it's right on the edge. it might be ok. if you can, install it and test with a dmm.

What will i be looking for via the dmm? Voltage loss?

yes. you could also install it, bump it for a while, and see if the wire warms up any at the battery. a hot wire is a sure sign that it can't handle the power.

K, i will have the amp set to 1000w rms but it wont play music on that wattage, rarely it might have a note that hits the 1000w mark but not continuously.

Right now i have an amp that does 500w rms tuned via -3db 50hz tone and on songs it usually playes in the 300w to 400w range, the song Put on by young jeezy will hit exactly 500 on a bass hit 2 min 48 seconds into the song.

So hopefully i wont be pulling too much power, i expect about 800 to 900 watts normally.

do you have an amp for components or speakers?

No i dont, the deck does that work.

Hmm according to this site: http://bcae1.com/images/swfs/wirepowercalculator.swf

with a 70% efficient class D amp and a 14.4v to the amp i should be ok for up to about 1400 watts at 14 feet.

sorry for double post, i cant seem to find any 12 gauge ANYWHERE to wire up the subwoofer to 1 ohm, will 16 gauge be ok for 1000w ?

EDIT nm, got some at walmart.. Now i just need to find a 100a glass fuse :| or ill have to change to a chip style fuse holder.

edit: got them on EBAY 5 100a fuses for 6.00 //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
