Power Specifications - Full Range Channels

RMS Power @ 4 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

160 watts x 4 channels
RMS Power @ 2 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

250 watts x 4 channels
Bridged RMS Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the RMS power created once an amplifier is bridged.

500 watts x 2 channels

Amplifier Specifications

Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
Razor (Power Acoustik)
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

D
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.

Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.

2000 watts
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

1000 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
4 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
4 ohms
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
No
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-pass (LP)
High-pass (HP)
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.

good bang for buck

November 25, 2013

Decent little amp for what it costs. Puts out good enough power, I seriously doubt it does rated, but good enough. It's a little lacking in the controls dept, ie, no subsonic, no bass boost, fixed xover points. But it does what I wanted it to. Powering 4 6x8 components on the front two channels and rear is bridged to a 8" sub. It barely even gets warm. Pay attention to the wiring diagrams, for some reason Power Acoustik didn't follow industry standard here. Two of the wires w/black stripe are actually +. Overall, pretty pleased with it, small footprint, doesn't heat up, and puts out amazing power for the size of the thing. It is Class D, you do hear some more distortion vs a class A/B, but it's not much, and to me it's tolerable considering I didn't have room for this big of a class A/B.

Great Amp For The Money!

February 16, 2014

I bought this amp to power a pair of Kicker 6" X 9" 's and a pair of 12" Bazooka subs. All I can say is I was not expecting much but was pleasently surprised. Really brought the Kickers to life and only needed half gain. Decent sound quality and amp stays cool. Very compact and basic. Crossover is lacking features but most decent head units do the tuning. Set It and Forget It. If your looking for a good value, basic, compact amp.....This is a good choice.

powerful little amp - specs are nonsense, but on my '13 street glide it runs my MM651 Polks in the fairing and my Pioneer 6x9 in my saddlebag lids...
just take the end caps off and it will fit on top of the radio (Stock or Aftermarket). for a 4 channel amp, you cannot beat this one (in fact I think it sounds a tad better than the one I had before this one.

I bought this amp in trust that sonic electronix sales and promotes good quality products and they have delivered every time. This amp is incredibly small for the power that it is putting out and it does what it says it's supposed to do. I bought it to push my two precision power component speaker sets and it sound loud and extremely clear. Amp doesn't get hot nor does it clip or distort. This a great amp from power acoustic and I recommend for interior music installs.

Best Answer: Hi,

-Can I add a sub remote to this amp?

Yes, but not an OEM one. It obviously doesn't have input for Power Acoustik remote, so you would need to get a Universal Bass Knob, like the NVX XBRC. It'll work the same way, and is a very common addition.

http://www.sonicelectronix.com/item_40536_NVX-Universal-Bass-Knob-XBRC.html

-do you think it will perform well with MTX TNE212D

We assume you are asking if the AMP will perform well (not the remote). To be fair, we suggest an amplifier that is specifically meant for subwoofers, not a full-range amplifier intended for door speakers. Nevertheless, the figures do fall within that which the amplifier calls for, albeit barely. Still, we would suggest a strong, better equipped amplifier. Give our sales team a call if you need further assistance.

I have a 1988 Ford Ranger that I am restoring, I was fortunate to get (4) Q-power 10" woofers in an enclosure that fits comfortable to my liking and it bangs just needing the correct amps to push these subs. I am thinking about purchasing (2) of these amps just for the low end and maybe (2) Power Acoustik RZ4-2000D for all of the Coaxials and additional tweeters.

Best Answer: Hello,

We can't speak on the subwoofer vs amplifiers, because we don't know what subwoofers you are referring to, as you've only provided a description. We would need a proper model number to provide an accurate answer. As for the Speakers/Tweeters vs Amplifier, four speakers on one amplifier and four tweeters on one amplifier will work well. The system would have to be fine tuned, consult an installer for that, and would require a steady steady from the source. The figures provided by this manufacture can be a bit ambitious and often only reached at very high voltage level, but this works in your favor, as long as the system is properly tuned.

i have (4) 6.5" jbl gto 628 on my doors and on my rear deck i installed (2) 6x9 jbl p963. i have a precision power black ice ba1000.4 running all speakers. the door speakers are on ch 1/2 and the 6x9s are briged on ch 3/4 and obviously it handles until the amp gets hot then goes into protect mode. i am thinking about getting this amp. my question with this amp is will it put the amp in protect mode when i turn up the volume. i am also running a l.o.c. from my factory radio?

Best Answer: Hello Ricky,

Both Power Acoustik and Precision Power are fairly entry level manufactures. In fact, they are essentially the same brand. However, you may want to give each Rear Speaker its own Channel. Bridging the rear channels is not necessary, and is likely stressing the amplifier, causing it to overheat.
