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.

70 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.

115 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.

230 watts x 2 channels

Power Specifications - Subwoofer Channel

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 speaker(s) or subwoofer(s) 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. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
270 watts x 1 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 speaker(s) or subwoofer(s) 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. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.

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.
Phantom (Precision Power)
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.
5
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.

900 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.
No
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.
Yes
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
Yes
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Best Affordable CLASS D 5 CHANNEL AMP for the Money

April 17, 2014

This amplifier and brand is the best kept secret. I knew of this brand since the late 80's early 90. Precision power has been around for a very long time. Precision Power have been on a bit of hiatus over the years. So, the younger generation, might not know of this brand when it comes to car amps.This company has a reputation for quality products at the best prices. Precision Power were consider a premiere quality brand back then and they seem to be making a comeback on the market. I bought this amp before the Christmas Holidays. I knew, what I was getting before the purchase. I thought, it was a price error. But, No Folks, This is the Real Deal. For this price point; This is a real steal.... You're getting more than your monies worth. This amp is POWERFUL, CLEAN, SOLID AND COMPACT. It will fit in a multitude of places in your vehicle. I highly recommend this amp. If, you want quality at a low price look no further. The specification speaks for itself!!!

Great price with plenty of power

September 3, 2013

There are other brands with the same board that this amp uses from NVX 900.5 and polks pa d5000.5, but this PPI have the lowest price and more watts per channel especially the sub channel. I was worried that this amp might cause hissing noise, but nope. Everything sound nice and clear. I have a 4 volt pre out from my pioneer x4500bt and I set it at 3/4 volume which is 30. My gains are at half for all channels. No distortion.

Great Amp!

March 28, 2014

This amp was an awesome buy! Precision Power has been around for quite a long time, so I knew their reputation before buying this amp (always made good stuff). I put this in my son's car to power his whole system, and the mids and highs are crystal clear along with powerful bass. The remote bass control is good for turning the bass down quickly when the blue light specials are enforcing sound ordinance laws. Who wants a ticket for listening to a little bass ((((( right? If you're looking for a one amp solution that's clear and powerful, then this is it and the price couldn't be beat. Thanks SE

Fantastic amp

March 16, 2014

Couldn't be happier with this amp, solid construction, looks great, sounds absolutely amazing, but the best part us the power, I run 6.5 components up front, 6.5 coaxial in the rear and a dual voice coil single 12 inch sub which is paralleled down to 2 ohms. The system truly pounds! I could not belive the power and sound quality.

Best 5 Channel Amp for the price.

February 8, 2014

I spent a few months researching, asking questions to dozens of people who were "experts" in car audio online and elsewhere about Speakers, Amps, etc.. Most of what I had initially had in mind changed after their input. One resounding recommendation was the buy the PPI Brand amplifier. Low or Medium high budget.. everyone liked the quality. I originally was going to buy a PPI 900.4.. but at the last minute found the PPI 900.5. In my car (350Z) I have four 6.5" speakers.. and the front 6.5" speakers are in the doors low.. and the tweeters are in the panels by the windows (components factory). So I needed something to power 4 6.5" speakers with 1" tweeters (aftermarket) that ran 70-80watt RMS per speaker and MY choice on the Sub was a JL 10" sub that ran at 300Watts RMS. The PPI 900.5 was about as close as you could get to these needs (but don't be afraid to buy MORE amp than your speakers require (you set the gains remember). I was hesitant about a "Class D" amplifier to begin with.. having always used Class A/B.. but I went with about a dozen recommendations and bought it. I've since installed and wired the whole car myself.. and am 10 times over more impressed than I ever thought I would be with this setup -- and the Amp drives it all. A cheap/bad amp gives unclean power and you hear that. I have supreme Sound Quality.. incredibly SPL .. with Clean Mids, Bright (but not overly bright) highs.. and the 10" Sub is in a Sealed custom box for the vehicle at .66 Cubic Ft,.. and this amp drives it very, very well. It's tight, quick response bass -- but if I'm watching a movie on my DDX470's DVD player, it's like being in a Movie theater with the rumbling bass etc. Bottom line -- Don't hesitate if this amp meets your power requirements.

Can I the 4 channel at 4 ohm and the subwoofer at 2ohm with this amp?
Chris S on Oct 15, 2014
Best Answer: Yes that works perfectly. I as using the sub channel on this amp to run 2 Infinity Reference 1262W's Utilizing only one voice coil per sub. Wiring them in series brings a 2 ohm load to the amp. They sounded pretty goo just weren't loud enough for me. I have since upgraded to 2 JL 12w3v3 running off of a JL jx1000/1d.

Best Answer: Hey Darin, first you need to get two 1-male to 2- female connectors(http://www.sonicelectronix.com/item_45066_NVX-XIN2F.html) and attach them to each of the rear RCA cables on the rear of your Clarion head unit. Next you will connect your P900.4 to the front channel like normal, and connect it to the rear like normal, only you will now have 2 extra RCA cables left that you will use to connect your 600.2 with. I hope this is clear enough to answer you question
