Pros/Cons of having subs at a 1 ohm compared to 4 ohm?

Question

What are the pros/cons of wiring my subs to a 1ohm load comapred to a 4 ohm load? Im scared from what im hearing that my subs/amp are gona die out quickly as everywhere i hear it says it will overheat and what not. Do you think it is fine to have two subs running at 1 ohm, whereas my amp is stable at 1ohm? Im on a pretty tight budget btw.

Answer 1

less resistance

Answer 2

It's much easier (and cheaper) to find an amplifier that can produce 1000 watts at 1 ohm compared to an amplifier that can produce 1000 watts at 4 ohms.  I only know of a few that can do this with a 4-ohm load.  With amplifiers that are rated for different power output at 4 ohms, 2 ohms or 1 ohm, the trade-off for extra power is more heat and more distortion when they're used with lower impedances.

However, if you have an amplifier that carries a CEA-2006 compliant 1-ohm power rating, and you use the recommended gauge power cable, then you shouldn't have to worry too much about overheating.
