Please retype that in english. You want to know how to get your subs down to 1/2 ohm? First question is, is your amp 1/2 ohm stable? What is the ohm load on your subs? Are they dual voice coil?
never seen a 1/2 ohm stable amp.... Maybe if it cost you like a billion dollars best I have seen is a 1 ohm satble amp and it cost a good bit.
mmats have a line of amps stable to 1/2 ohm. I was running my XXX's off a d3000.05.Originally Posted by Grnblur
Also the US Amps VLX series amps were stable down to 1/4 ohm.

my amps are mono so i would say 1 ohm stable and yes they are dual voice coil
is your sub a dual 2 ohm or dual 4 ohm. only one sub or two?
RESIZE PIC PLEASE
that amp is 2000 watts at 1 ohm and 1600 watts at 2 ohms, but let me know if your sub is a dual 2 or a dual 4. i highly doubt that amp is stable at 0.5ohms.
RESIZE PIC PLEASE
the amp is stable 1 ohm and and it a 2 ohm sub and yes i have 2 subs two amps

just wire up the subs individually in paralell then to the amps.
Also have the subs in seperate enclosures to prevent any possible damage to them.
ty i will give it a try
.5 ohm is so close to a short circuit so the amp will more then likely run a lil hot so u might wanna get a cooling fan from my experience with running amp lower then 1 ohm

I love my USA AMPs...I got the in early 2000...back when Jack owned the company in Florida....MUCH different than now.
Perhaps the amps might be "slightly" modified.
My US 50HC (rated at 25x2) will do nearly 1500 at 0.5 ohms. I have even fed them as high at 17.3 volts at one pont with no issues. 17.4 volts, however, was a problem.

i might just stick with 1 ohm i will post how it goes. Is there any place near cleveland,tn that will tell u how hard u hit in db and spl?

wouldnt that be considered a cheater amp by current rules?
I know I did a clash of titans event a couple years ago and I tried to get into the class for 300-500 watts at 4 ohm but the asshats wouldnt let me cause someone heard me talking to another guy and told that I was running 2500 watts. Either way, I damn near won the bracket racing and walked away with 3 trophies. 2 first places and a second. That show was funny because I was only 6 db below a full out SPL truck running 6 15's in a wall and nearly 12k watts.
If anyone wats them they are for sale.
Sort of....even then, I competed in the Pro ranks, so we could modify equipment. So, by todays rules, it might be "cheating" in some classes and organizations, but it was not for me back then.
Back in 1997(ish)...High current amps were the rage. Jack at US Amps was buying parts for his amps from the company I worked for, Streetwires, so we had a good relationship. I was one of the first to have the Streetwires X-14 battery system (isolator, alternator, regulator, and battery pack), which was capable of over 17 volts...we tried the amps at 16.5 volts input, and went up from there. They gave out around 17.1, and we reworked the insides a bit with larger caps and such...this happened a few times, until we settled on 17.3 votls (or somwhere near there).
I still have the 3 amps, as well as the electronic crossover....

can you show me a diagram or explain when u mean in paralell? i have heard alot of people talking about it but they sound like they do not know what they are talking about
my mmatts 4000/1 is 1/2 ohm stable and didnt cost me a billion dollars lol... WOLFENBERG has a 1/2 ohm stable amp but their products are shiit..... seperate chambers for the box.. and if your amp is just 1 ohm stable dont wire below it or you will fry the board
we've all tried the same thing.. did that with a cheater amp and high volt alternators.. told the judge stock rubbed grease all on the newer one lol 350 alt. and 300-500 but my lil cousin who was 8 at the time said wat about the amp under the box..... (****) so they put me in a different class.. still won the south carolina division for mid size sedan... damn i miss the cavalier
I have a US Amps HC25 for sale if interested, it is a half ohm stable.
lol thats how i did hook them up in the first place just didnt know there was a name for it but thank u
STAY IN AUDIO LONG ENOUGH, YOU WILLL LEARN IT ALL
RESIZE PIC PLEASE
you will also go broke upgrading all the time.
JL audio's website has a pretty good tutorial section.
OMG tr00f
no kidding i work at taco bell and your rite im trying to hurry up and finish and i am always broke all i left is the 2 line drivers ( they are on the way) and the cap got to wait tell next check
you can skip the cap as it will do nothing more than add another draw on your alternator. instead get yourself a HO alt and upgrade your big 3.
big 3 haha i dont know what u mean lol i have looked around for a bigger atl but havent found any for my car
big 3 are:
Alternator to battery wire
Battery to engine block
engine block to chasis
upgrading those wires with a heavier gauge will increase the efficiency of your current charging system.
thanx man u been a huge help
tr00f again.. the big three is what i do to all my cars before i even get a system.. i do it with 0awg just because its all i use lol
I have a couple dozen feet of red stinger custom pro if you want it. I'll let you have it cheap.
sweet how much do u have and how much would u let it go for? What gauge should i use? 4? or 0?
I have 1/0 and you don need anything that big.
But I'll sell it for $4 a foot. It will typically cost about 6.
