100x4 amps

[jacka 10+ year member]

Looking for a good amplifier that pushes 80-125 x 4 @ 4 ohms. Only got a d3 400.4 right now and wanna push my components a bit more. budget around 250-300 maybe?

Phoenix Gold Xenon 100.4.

Hell, you could probably pick up a 200.4 in your price range.

the x100.4 is nice, but i havent been able to find one for a long time. haha. how much of a power loss am i looking at from 14.4 to 13.8 volts? All the newer amplifiers are CEA 2006 certified and rated at 14.4, but my system usually stays around 13.8. So how much power would I be getting from a 125 x 4 amplifier running at 13.8 volts?

Infinity has a nice amp in that price range. 111x4 at 4 ohms, 140 x4 at 2 ohms

Power (watts) = current (amps)^2 x resistance (ohms)

So basically the more votage = more power...but more resistance = less power.

Really depends on the speaker's efficiency and amplifier efficiency (typical class a/b is about 50-60% or so) and the amp's power supply to begin with. Then you have the resistance of the wire and the voice coil. So a good estimate of the actual power in watts the speakers are driven by is maybe 50 watts rms.

In the same delima, but I'm leaning toward a Kicker 600.4 120x4

i also wonder if the hifonics do their rated power.

there are plenty floating around, pm HCCAfan and see if he has any if not see if he has the 2k6 model..

Hmmm, last One I bought was from HCCAfan about 3 or so months ago. Doesnt hurt to ask, even though I know he is selling the new style amps.
