Default benefits of running at .5 ohms

I am getting some new subs the 2 18in sundown zv3. I have a sundown 3500 amp. My question is can i run that amp at .5 ohms without problems. Also what are the benefits of running at .5 vs 1 ohm? I am debating on what coil config to get thanks guys.

Benefits of .5 ohm: Helps combat impedance rise, which in turn draws more power out of the amp. Yes, you can run the 3500 at .5 if you have sufficient elctrical power.

Downside: seems to be a bit harder on the amp that 1 ohm, uses more power due to decreased efficiency.

ull get a little more power out of the amp.. ull see close to rated power at 1ohm when wiring to 1/2 because of rise.. but it is harder on ur electrical obviously

I would run at .5 ohm. The amp will never see anything close to 1ohm because of rise. I did an extisive test on this a while back, results are posted on another site. Your amp will be fine. Be sure you have the electrical to back up that amp,be it 1 ohm or .5 ohm.

you won't hear the difference between the two loads. just producing more heat than anything.

but reading around here most amps that people drop do .5 never hardly get warm as long as they have the electrical. but i can see if ur running stock electrical lol but im gonna assume your not.. and ur box rise will spike and subs get warm then should be 1 ohm.. right?... id try 1 ohm and check ur box rise then see if you can go down to .5 efficiently

i vote go to .5ohm but only if you have solid electrical. Im actually dropping my saz3500v2 to .5 soon when i get my new sub. But only bc im rising to 2.6-2.8ohms so hopefully my new box and a dual 1ohm coil sub wil help me get some more power out of my amp.

you could make to most effecient box possible and run it at 1 ohm. Most of the time you do hear a difference going from 1 ohm to .5 ohms ,at .5 it will most likely will get louder..and at 1 ohm it will sound cleaner and but maybe not as loud...alot of variables come into play as well..its kind of something you need to try in your own set up to know.
