can someone tell me what this means(amps)?

Question

Amplifier: 360W continuous power @ 4 ohms, bridged




Amplifier: 200W x 2 @ 2 ohms RMS




Amplifier: 120W x 2 @ 4 ohms RMS




Amplifier: high-pass crossover 45-300Hz; low-pass crossover 32-320Hz




Amplifier: 0, 8, 15dB selectable bass boost


its for a sub/amp package on bestbuy...infinity-costs a 100...2 12's and that amp

i meant to say insignia not infity i was watchign a commercial and i switch ed them up my bad lol

Answer 1

The term 'amplifier' has become generic, and is often thought (at least by some) to mean a power amplifier for driving loudspeakers. This is not the case (well, it is, but it is not the only case), and this article will attempt to explain some of the basics of amplification - what it means and how it is achieved. This article is not intended for the designer (although designers are more than welcome to read it if they wish), and is not meant to cover all possibilities. It is a primer, and gives fairly basic explanations (although some will no doubt dispute this) of each of the major points.

I will explain the basic amplifying elements, namely valves (vacuum tubes), bipolar transistors and FETs, all of which work towards the same end, but do it differently. This article is based on the principles of audio amplification - radio frequency (RF) amplifiers are designed differently because of the special requirements when working with high frequencies.

Not to be left out, the opamp is also featured, because although it is not a single "component" in the strict sense, it is now accepted as a building block in its own right.

This article is not intended for the complete novice (although they, too, are more than welcome), but for the intermediate electronics or audio enthusiast, who will have the most to gain from the explanations given

Answer 2

Amplifier: 360W continuous power @ 4 ohms, bridged

means the amp will push 360 watts RMS (root mean squared) into a 4 ohm load when the amp is operated in bridged mode.


Amplifier: 200W x 2 @ 2 ohms RMS

means the amp will push 200 watts RMS into a 2 ohm load out of both channels (X 2). This also means the amp will have to push more watts for the lower load which causes the amp to run hotter than it would at 4 ohm per channel as below...


Amplifier: 120W x 2 @ 4 ohms RMS

mean the amp will push 120 watts RMS out of each channel. This also will push less watts but will sound better, last longer and run cooler.

Amplifier: high-pass crossover 45-300Hz; low-pass crossover 32-320Hz

This is the frequency range. high-pass is for high frequncies (not for sub woofer use) and the low-pass is for low frequencies (not for tweeter use).

Amplifier: 0, 8, 15dB selectable bass boost

is just that, bass boost.
