Wiring subs in high power application


Recommended Posts

Posted

I am currently re wiring my dual 1 ohm subs. I and using 8 gauge power & negative wire. The amp is roughly 3 feet from enclosure. Is this wire thick enough?

By the way I'm looking at 8870 watts of power across 3 subs.

I'm starting out and 1.5 ohms however I will drop it to .67 ohms from time to time.

At .67 ohms I would see 14,000 watts.
