zapco amp question

[elkiko2004 10+ year member]

does the zapco amps i mean 1000.4 and 500.1 are fully regulated ? like the jl amps ? 11-14 v the same power ?

nobody knows ?? //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif in their web site doesnt say anithing at all, that why im askin you

They just say that they use both unregulated and regulated power supplies depending on the application.. My owner's manuals do not say which amps are regulated and which are not...

You'll have to call Zapco...

The C2K series are semi-regulated, they increase in power as load drops and voltage is increased. But not like a JL or Phoenix Gold Xenon that will give same power into 2 or 4 ohms regardless of voltage.

Reference and DC Reference are loosely regulated meaning they'll put out more power as voltage increases but won't put out crazy power as loads are dropped like C2K.

i-force amps are highly regulated.

All nice amps but too expensive.

ZAPCO C2K 9.0XD

The Zapco C2K 9.0XD is in a class of its own. It is very apparent that this amplifier was not designed just for the SPL competitor, but for the serious listener who is an occasional volume junky. Its build quality is second to none, as is the flawless and well thought out exterior.

This amp uses the Tripath Class T drive module. Unlike the class D amplifiers, it is capable of full range audio, even though it is not likely that someone will be using this much power on anything other than a subwoofer system.

The Zapco is the only amplifier of the bunch that employs a regulated power supply. While this type of design allowed it to produce the greatest amount of power at battery voltages of 12.5 volts, unlike the others its power did not increase but slightly at higher battery voltages. This can be seen in the results, as this amp produced 2100 watts at 12.5 volts and 2108 watts at 14.4 volts. This achievement merited first place in the former category and second in the latter. As for the reactive load test, this amplifier produced 2439 watts, good for third place, just slightly off the pace of the two Crossfires that wrapped up second.

The C2K 9.0XD includes a control unit that can be mounted in an area that is easy to reach, and remote display to show your adjustments. The control unit allows the user to adjust turn-on delay, enable the limiter, control gain, and select the display mode (these can be adjusted at the amplifier as well). The remote display also presents average and peak power, battery voltage, supply voltage, and internal temperature. A very nicely packaged and easy-to-use feature. Note: There is a 4-ohm version of this amp.

Layout:

This amplifier does not compromise on layout. Twelve low ESR, high temperature capacitors are used on the power input. Eight low ESR capacitors are used in the supply's power output section. Dual toroid transformers are used in the power supply. As this supply is regulated, it employs dual output chokes. Zapco also uses surface-mount components as well as through-hole throughout the PCB. Control functions are accomplished by a 16-bit microprocessor, while dual uP controlled fans are used for additional cooling. Power and ground connections are similar to the Earthquake's and can accommodate 0/0awg wire. However, the speaker outputs are standard spade-style that accept 10awg wire.
