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.
350 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.
Sedona (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.
1 - Mono
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.

850 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.
1 ohms
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
0.5%
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)
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

40 - 220 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
10 - 50 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
85 dB
Bass Boost
The objective of the bass boost is to get more kick out of your subwoofer. It is a circuit that emphasizes the lower frequencies at a given point. The bass boost should always be set first before setting the gain. This feature is known for destroying subwoofers and is commonly used incorrectly, so be cautious.
0 - 12 dB
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).
No
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.

Budget Amp

May 1, 2014

I've owned this amp for two different sets of subwoofer setups. The previous was for 2 12" Kicker CVRs wired at 2 ohms. I had that when I barely knew anything about a system. I gave that amp hell for an entire year, and it never quit. I even mixed up the ground wire and power wire once and turned the car on (blowing the inline fuse). It was still a trooper. Now I have a single 12" Kicker L7. I have it wired down to 1 ohm. I had the sub lying around, and decided I wanted a cheap amp to throw on it. So I decided to go with this. And it'll definitely push it. I have the L7 in a ported ground shaker box, and it'll slap. I have a 4 door Tahoe so there's a lot of air it has to push. I tuned the amp with a digital multimeter, and I believe it can put out more than 850 watts RMS @ 1 ohm. It does get warm to the touch, but I also don't have it where it can optimally ventilate. The most I've ever played is about 2 hours straight at 3/4 of the max I tuned to. PROS: Solid amp for the money. If you're on a tight budget, this is the amp for you. Does at least its rated amount. Nice exterior design. CONS: A bit larger than I'd like it to be. It does get a bit warm, so just make sure it can ventilate a little.

Excellent Amp, Price, and Performance

June 25, 2013

I purchased this amp about a month ago. I installed myself and it's hooked to an older RF T1 Dual 4ohm sub (equivalent to the current RF model P3D4-12) and wired into a 2ohm load. I built my own 2.25 cu ft vented box. Man does it pound! It's in an Accord and I've never had anything perform better! I'm the kind of guy that always seems to push the limits of my equipment. For the first time in 15+ years I have an amp that I don't have to turn up all the way. With the bass knob set at 1/4 to 1/2 I can be heard up to a half mile away! I LOVE this amp!

Great Amp for the Price

May 31, 2013

Just bought this amp, and so far am loving it. Have it hooked up to an RE Audio SEX 15 at 2 ohms running in a 2 cubic ft sealed enclosure, and it pounds. Definitely impressed. Bought it for the fact that it had the speaker level inputs and remote volume knob to integrate with the factory stereo in my wifes SUV (she is not into car audio at all...) Was the perfect compromise for us (satisfied my obsession while not breaking the budget)

Great Amp

February 26, 2013

Bought this amp a couple months ago. I installed it myself. I use it to run 1 JL 13tw5-3 It is enough power for my purposes, but I don't think it pushes my sub to its limits. Great amp for the price though!

Don't let the off brand throw you off!

June 19, 2012

I was very scepticial about buying this amp for it being a class d mono block. After hearing good and bad things about them I went ahead and ordered it to power 2 12" kicker CVRs and let me just say that it supplies more then enough power to handle the 2 subs just fine and the extra bass knob really is handy for adjusting the subs amps output. It has gave me no problems at all and has never even over heated. The only small downside is that the amp does not receive the high frequency bass tones as well as normal mono blocks or 2 channel amps. Overall very satisfied!
