Amplifier Specifications

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.
8 AWG
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
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.

50 - 200 Hz
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.
Yes
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

Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
300 watts
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
35 - 150 Hz
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Sealed
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
1
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
Hatchback Style, Angled Back
Height
The height of the item, measured from top to bottom, in inches.
15"
Width
The width of the item from left to right (side-to-side) measured in inches.
19-9/16"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
7"
Second Depth
The second depth is used only when the box is slanted or angled. This value is the top measurement and it is measured in inches.
11"
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
2
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.
Carpet
Final Wired Impedance
This is the final impedance of the system as the amplifier will see it. If the final impedance is for two sets, it means that the enclosure has two sets of terminals at the listed impedance.

Got this because I just a little more bass than what I got from the factory. It does just that, you won't be winning any SPL competitions but it adds just enough. Install was simple, power and ground and got my signal from the factory woofer in the deck and set the remote to auto on! Small enough so I didn't sacrifice any trunk space yet sounds great!! Would recommend!!!

surprisingly great subwoofer

March 3, 2014

Upon looking at this speaker you don't expect much. But once it's playing you can hear that quality rockford produces. This sub won't break glass or do hair tricks, but for the price you pay, it's a steal. Would recommend for anyone who has little room to spare but still wants great sound.

Pretty good

February 25, 2014

Honestly I ordered this because I needed a temporary setup while I save more money to buy my dream system. There is nothing really bad I can say about this woofer, it has great sound quality, its compact, the only thing I don't like is that bass below 35 hertz sounds crappy because its a sealed box and the box is also way too small. If this was in a 2 cubic foot ported box tuned to 32 hertz, it would sound even better with better sound quality. Some advice I can give to people who have no idea how to set crossovers: Set the lowpass on 80, this means only bass 80hertz and below will go to your subwoofer. On your headunit, set high pass for the door speakers to 85 or 90, that way only bass above 85 or 90 hertz goes to the door speakers and not the sub. Put this sub as close to your tail lights as possible, and face them toward the tail lights, basically by corner loading this sub, youll get the loudest, deepest bass.

Cost Effective, Quality Bass!

October 26, 2013

Well first of all let me say that I was pleasantly surprised by the RF P300-12. This really is a fantastic value product to get some solid bass happening in your ride. I had 2x12" 500W RMS subs 10 years ago and that was great for my early 20's when I wanted to turn heads. Now in my 30's rolling in a demure 2013 Ford Escape I still like quality bass but just don't need the SPL. But don't let that fool you, this thing will still rattle your rib cage! I actually ordered this on a deal with an 8 guage install kit included. That gives it all the power it needs. The install took me a full day as this was my first sub install and it took me a couple of attempts to patch into a good speaker signal, not to mention fighting through the myriad of plastic panels in my ride. An experienced installer could knock this out in 3 hrs no sweat. One trick on the speaker signal, don't go for a left or right speaker, when the mix sends the bass left or right, your sub will follow, and that sounds ugly. You want a direct sub output or central dash mounted speaker not subject to balance. The length of the signal leads is no problem as long as you run it away from the power cables. The sub takes a few weeks to wear-in so I recommend running it at no more than 30% (remote level) during that time. You can hear when it switches from accurate bass reproduction to just woofing without care for quality. Keep it under that point during wear-in and it will improve with time like a good wine. In terms of setup, the 'bass boost' and 'gain' features don't do anything for me. They are basically redundant for my install and using them impacts accurate bass reproduction. The included remote gives me all the gain I need and I never need or want to run it above 50%. The crossover runs from 50Hz to 200Hz and is a handy feature. I have mine set around 65Hz and that suits me. The convenience of being able to remove this from the car at any time is a huge benefit. The sealed enclosure is perfect and you can tell this is a well tuned quality unit. Ports are for people who want to puuuush air. I want quality, tight reproduction and low frequency response, and that's what you get with well tuned sealed units like this. If you're after good quality listening level bass at low cost, the convenience of removing at any time, this is the product for you. Buy it.

Let's be blunt...

October 24, 2013

All I have to say is it blew me over when I turned up after installing.. I expected just a nice touch of bass to my system. Instead, it really overwhelmed when it over achieved my expectations. Honestly to god, this could probably go against some dual 12 inch subs for this single 12 inch.. Have my bass nob turned up 1/3 of the way and it shakes the mirrors. It might just be because I have a little mustang and not an SUV, but this thing hits!!

If you are wanting some bass to complete your system I highly recommend this unit. Its almost spiritual. Its hard not to turn it up. The bass vibration going through the vehicle and yourself is incredible. I have to wear ear plugs when I get carried away with the sound. This was my first purchase from sonic electronix and was very satisfied with the transaction.
