electrical for audiopipe ap30001d?

Dropping an amp to 1/2 ohm doubles the output current (up until the amp just can't put out more at least) and makes everything less efficient so the power supply in turn draws more current, often times inducing more voltage drop which calls for MORE current to maintain the same output level - again, turning into a cycle if it continues until something fails
From sundown himself, so in other words unless you have the power to back up half ohm you shouldn't do it.

No. This is not true in all cases. Most of the main stream amps for example use protective cutoff's at below rated impedance's. RF amps for example put out the same, if not less @ half ohm compared to 1 ohm.

how am i not getting 3000+ out of my amp when my voltage stays at or above 12v?
last time i checked, sundown rates there amps at or around 12v, so if im at that voltage, how do i not get 3000w+?

Because your not

Just because it's rated at 3k doesn't mean ur getting 3k. Factor in impedence rise and ur getting 1500-2000 if not less

This

X2 yes, it's not possible to run it at 1/2 ohm (true impedance) on a wimpy 105a alt and a little battery and get full power. I'd love to see you clamp it and prove it since your so sure. You must have a really high box rise.

Pretty much this

somethimes this, usually not this

Need power to make power

u have no powa

alt n batts

get sum

hit me back

nukka

Does audiopipe do rated??

are u retarted in the head?? ;0( ?? did u forget about inpedence rise???

all the way baby!!

This particular amp does, and the 1500w version does as well. I am not sure about the new 3500, I would assume it does but not sure.

i know imp rise......i know im not getting only 1500 to 2000w "if that" like the other guy said.

i say its at 1 ohm after rise, just for the sake of the argument.

ok so its RATED 3000w rms @ 1 ohm @ 12.8 or w/e jake rates them at.

that means AT 1 ohm, AT 12.8v, itll do 3k right?

if my voltage doesnt go BELOW 12v, it has to be on or pretty close to 3k, right?

Only way to tell is to clamp it. I am sure it would help to know what it is actually doing power wise.

if my voltage is at or above 12v at all times, i fail to see how the above statement is true.

yes, it might not be at .5 exactly due to rise, but as soon as i find someone with the tools to clamp it, ill be more than happy to clamp it and reply the results in this thread with pictures.

If u set ur gain according to ac voltage out then you aren't getting 3k at 1 ohm either. If u used an o scope or listened for clipping maybe. But simple logic will say u aren't getting 3k. I'm getting 4k+ and drop to 12.3 with 300 ah of batteries and a 220amp alt. I don't see how a small batt and 105amp alt can sustain 3k if mine barely sustains 4k

If your going to get a AP, I would get the Ap3500. People say those things are beast for the price, and somebody ran them at .5 ohms daily. Just get the electric

this^^

ive heard good things about them.

and if you stop being stingy on your electrical, these will do some serious power at .5ohm

idk but im going by what the amp is rated at, and at what voltage.

as far as im concered, if im at or above the voltage the amp was at when the ratings were set by the manf, then i see no issue here. i didnt use an oscope, i adjusted it by ear to where there is no clipping. theres no where that says "you arent going to get 3000w out of your sundown 3000d @ 1 ohm @ 12.8v UNLESS you have a HO alt"

IF you're steady @ 12.8+ volts, and its at 1 ohm, then youve got 3000w....

I thot imp.rise only occurs on Bass tones in competitions or if a song has a very prolonged bass note? Does it have a major effect on daily listening to music?
