Just a quick question.

i was thinking about this for awhile and i was wondering why it seems to be less common to wire down to .5 ohm. Correct me if i am wrong but with imp. rise wouldn't it be closer to 1 ohm? A lot of people wire to 1 ohm and wouldn't it because closer to 1.5 or 2 ohms?

I'm obviously no expert and input would be appreciated

Thanks, Snowrider

Probably because there are far fewer amps that are .5 stable.

Alright so lets say you have 2 4 ohm DVC subs and they are wired to 1 ohm, and because of imp rise, your subs aren't getting the full power. Even though there is imp rise is your amp still taking a 1 ohm load? Could someone please explain this?

There are a not a lot of Dual 2 subs out there. But Yes you can do .5 on some of the good 1 ohm amps and be a lot closer to full power, Just need to have the electric to back it up and the Balls to try it.

We offten do a 3 dual 4's setup on a 1 ohm amp.

Also

Have you checked your rise and checked it through the entire Sub frequency range?

This.

Most of the time, imp rise would only raise a .5 load to .75 or so, depending on the coil.

But another reason why I wouldn't wire it down that low is due to the massive amount of current that amp would hog, the distortion increases exponentially, and for most 1-ohm stable amps, you void the warranty when you wire it down to .5-ohms.

Alright thanks guys you've answered my question.
