i had someone tell me i couldnt wire my 2 15" kicker cvr DVC 4 ohm subs at a 2 ohm load (on a brutus bxi 1606D).  is there any truth to this? im kinda retarded when it comes to the ohms thing, and yes, ive read over the ohms law page... several times. the subs were wired at 4 ohms (before the amp went out).  any answer is appreciated.

Simple answer is No, you can't wire (2) 4ohm DVC subs into a 2ohm configuration.
However if I found the right specs then the Hifonics Brutus bxi series amps are 1ohm stable. Why are you worrying about a 2ohm load? You can simply wire the subs into a 1ohm load instead.

eh, im not sure how capable of 1 ohm it actually is. it says it is, but... a lot of amps say that... and just ending up crapping out/over heating.

True. Alot also only give you around the 2ohm load rating at 1ohm instead of the specified 1ohm rating.
You said "before the amp went out". Were you referring to the Brutus or a different one?

If it is the Brutus amp that "went out" here's an excerpt from the manual concerning the on-board diagnostic system...
Description of the Diagnostic system built into all HiFonics amplifiers
The diagnostic system will shut down the amplifier, until reset by turning the head unit off, and back on. This state of affairs will be indicated by the front panel
PROTECT LED lighting up under the following conditions:
1 - A sort circuit on the loudspeaker leads.
2 - An internal amplifier fault that causes a DC offset on the loudspeaker output.
Should the amplifier go into diagnostic mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.
1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.
2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.
3. If the amplifier seems ok with RCA cables plugged in, connect the speakers, one at a time, and if one of speaker or its wiring is faulty, it will activate the diagnostic system.

i have the 1606d hooked up to 2 12" type-rs, wired to 1-ohm
it pounds the h*ll out of them, and doesnt get noticably warm at all

well, the amp would turn on and seemed to have a signal, but would produce no sound, so im sending it back to get another one (another 1606D). the amp that went out originally was a 1606D. i'd really like to wire it at 1 ohm next time. i'm just worried about how much the 1 ohm load would be with my cvr's. being that they're rated at 500 watts rms. anyone had any experience with putting CVR's under a lot of stress?

It's a strange situation, but I have my two 12" DVC 4ohm Kicker CVX wired parallel/parallel (which would present a one ohm load), and my amp is a Kicker zx1000.1, not one ohm stable. I have measured at the amp terminals, and the resistance is between 1.9 and 2.2 ohms. And yes, I am still running this setup with no problems. Still, no one has been able to explain it to me.  Here's a link to another thread.
