Wiring A Visonik V4000XD to .5 ohm Can it take it? Need more electrical?

[WOT]

K long story short. Ive got 4 15" AQ 15's in a wall, all run by a Visonik V4000xd @ 2ohm. Does 3000+ @ 14volts.

http://ampguts.realmofexcursion.com/Visonik_V4000XD/

I am THINKING of wiring down to .5 ohm. Now Ive obviously got a few questions, the car is a daily, and will the amp be able to take that daily?

As it sits now. @ 2ohm, I drop to about 11.8 at the lowest. But I have blown the mofsets before on this when it dipped into the 10's before I upgraded electrical

Im hoping someone else can chime in here with some knowledge of if this amp can even be wired to .5ohm. When I bought it I was told it was modded, most likely to be able to run @ lower resistance. But how do I verify?

My current electrical consists of a simple blue top main batt, second underhood big truck battery w/ 160min reserve, 110amp alt, big 3 in 0 guage, 0 gauge power run.

Curious of your guys opinions on if it doable or not as it sits, or if I need to upgrade. Im thinking I putting out right around 2000rms @ 12volts from the amp, any idea what kinda numbers I might see @ .5?

I figure after imp rise (which I know nothing about), that Id probly be up over 1ohm anyways right? I searched and couldnt find any info on modding/running these amps low

Thanks

if it drops to 11.8 now it will most like drop to about 10.xx when u wire it down that low. also i have heard mixed reviews about that amp so be careful with it before u slam on it half daily. u will need a bigger alt or bigger battery. i have some huge c&ds for sale if u wanna upgrade just the batteries., hope this helps a little

one of our guys has his at 1ohm with 5 batts and ho alt and he still dips in to the high 11s amp cuts off after a while of play

^^^ see what i mean. some say yes and some say no. might wanna call visonik customer support or something to get some accurate advise. either way good luck! lol

WTF ?? sorry dbl post

With what you have I would not run that amp at .5.I ran 2 of the hk4000d's last year.Both at 1 ohm daily and got just over 3k from them.At .5 I would not run them daily.They tend to get hot.I would oly burp at .5.

To run these amps sufficently daily you need 4-5 batteries in a bank in addition to your battery under the hood.

yeah they got nice and hot the one my friend uses cuts out at 180 i belive

I wouldn't run it daily @ .5ohm, that amp @ 1ohm alone creates a huge amperage draw. If at 2ohms your already dropping to 11.8, i'd expect mid 10s @.5ohm.

 

Thats the same amp as the MA HK4000D if i'm not mistaken and i've seen them take .5ohm for burps but that was with a huge electrical backing.

Those amps are not even 1 ohm stable, I have one at my house that I'm repairing. You could remove the output transistor gates so it will operate below 1 ohm but you will need a huge electrical, it will not be stable but will play at .5 ohm.

He did state it was modded.Even without the mod they will run at 1 ohm.However they shut down at .5.
