Just curious as to how everyone feels about running at a half ohm? would you or wouldn't you?
.5 ohm vs 1 ohm... pros cons?

I FINALLY realized this!!!! I love bigger amps ran at higher ohm now bc of the efficiency difference.

My question is this...
IF you wire higher and try to get more volume (Dbs) at say 40Hz, you WILL push the system harder to get the desired volume at that 40hz... and that could result in pushing the amps too hard.. with the rise up to say 3 ohms and cause clipping and excessive current draw, because the amps are rated at and will only be able to produce lower power at a higher ohm load.
If wiring lower gets you the desired output (Dbs) at that same 40hz, BUT running the system around half as hard... This will result in less heat and less current draw due to the fact that you only need to push everything HALF as hard to get the same results...(and you should have a little extra power left over to use at your "discretion").
At least this has been my experience with wiring down.
I DO agree that the responce WILL be much flatter running at a higher impedence, and most likely sound a little better too.

I run at .5 and .35 daily. I don't worry about the added current being sent to the subwoofers because it was a lot easier and cheaper to get a heftier coil in my subs than it is to pack the back of my limited space with 2 or 3 times as many huge amps.
But I'm also running a bank of 5 d3100s for a single Saz1500 now too

I've always run at .5 and 1. I like .5 much more as I have the electrical to back it up.

i totally agree i always plan to run a amp below rated impedance..
well except for the ultra picky ones that fry or protect right away ( like a kicker zx1500 tried running it at 1ohm..it played for awhile lol)

Imo. Saying you can hear the difference between 1 ohm and .5 is about as realistic as saying you can hear a 1 db change in a sub system. It's psychological. If you didn't know it changed you wouldn't hear a difference. The change in damping factor etc.. is not significant enough to hear a difference unless you are superhuman.

i have a 250amp MCR HO ALT w pos and neg 1/0 AT cca ran to my crescendo 3kwp @ .5ohms on my SKAR ZVX15d1 and my electrical is fine....12.4 lowest i seen...and i played full tilt yesterday for 45+ min and i couldnt get the amp or the sub even WARM
goin down the hiway i can barly push it under 13v....maybe 12.5 on sum clipped songs on certain notes
and i actually see a difference in my system from when i had 2 sa15s on the same amp wired @ 1ohm.....with the sa15s i could drop to the high 11s on certain songs.....im sure theres other factors in my cituation but i can tell my voltage holds better w/o a doubt running this 3kwp @ .5ohm

if ur talkin 2 me.....yea all SKAR AND SUNDOWN SUBS as far as i know only have DVC subs....i cant think of any "FORUM SUBS" that even offer a SVC sub

No. Two dual .5s can be wired to .125, .5 , 2 and not 1

you do that, but dont forget to check each coil in the pictures as well.

Are you talking about EACH subwoofer wired to 1? (coils in series)
