I can tell you now it didnt, and it let out the magic smoke.

means i get it for free!!!

Usually only true when your at the higher ohmage law.......not at the lower ohmage thus higher current demand.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Thats when amps like JL Audios will **** current like a a/b amp and kill a elect. system.Now at the higher 4 ohm loads they are very effiecient amps and very clean though.
Yes pimp heat is bad unclean wasted efficiency. aka.............VIPER

oh ya, that's what i meant by regulated amps are lower, the efficiency, not the ampere draw

there's something about the sound of 'em i like

i dunno, very distinct imo

i had a lanzar opti2000D, and that thing RIPPED

if i still had it so i could put it head to head, even at a rated 1600w rms @ 1ohm, it would still ANNIHILATE my hifonics

it just sounded MEAN

lol


thinking of going the IA 20.1 route, but dont feel like dropping the coin for the same power.

****, I LOVE that amp... just LOOK at those numbers and specs.

DROOL over that damping factor!

DROOL over that damping factor!

Which is completely useless, since you only need a DF of ~20 for it to not be audible!

haha just saw this...........opti 2000d ftw

Seem a lil hard to believe.

But what ohm is that efficiency at 4 ohms more then likely 8ohms which is doable.

Looks good though.

Is there a real bench test for these out there?

As long as you can supply the power, efficiency means squat for SQ.

so what your saying is as long as i can keep it near 13v or so i will be okay?

 

[vetkilr 10+ year member]

I guess SQ means nothin over 110-120 decibels then??

My MD2 at .5 had no Dampin Factor left and was Muddy and I had plenty of power goin to it...........and my car is far from a SPL car.............for now.

 

[iamamp3pimp 5,000+ posts]

Explain dampening factor to me please then....

 

[vetkilr 10+ year member]

Everytime you cut the amp load in half you cut the Dampin factor almost in half also..........so you lose quality.........PERIOD.

Explanation

In loudspeaker systems, damping factor describes the ability of the amplifier to control undesirable movement of the speaker cone near the resonant frequency of the speaker system A speaker diaphragm has mass, and the surround has stiffness. Together these form a resonant system and the cone may resonate in response to short audio pulses.

A high damping factor indicates that an amplifier will have greater control over the movement of the speaker cone, particularly in the bass region where the resonant frequency of the speaker system will lie. This damping gives a "tight bass" sound from the sound system.

For audio power amplifiers this source impedance Zsource (also: output impedance) is generally smaller than 0.1 Ω (ohms), and can be seen from the point of view of the loudspeaker as a near short-circuit. This low impedance very rapidly dampsany unwanted cone movements induced by the mechanical resonance of the speaker, and acts as a very effective 'brake' on the speaker (just as a short circuit across the terminals of a generator will make it very hard to turn).
