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.
Big Bang (Planet Audio)
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.

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 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.

4000 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.
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
1 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Not Bridgeable
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.
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.
1 pair
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 - 250 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.
100 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 - 18 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.
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).
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
250A External Fuse
Some amplifiers can be "strapped" together in order to increase the output of a single audio channel. These amplifiers feature RCA preamp outputs, allowing you to pass the signal directly from one amp to the other to ensure consistency.
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.

great amp

May 30, 2014

i hooked this amp up to 2 pioneer pro 12s 1000 rms each sub. i wired the amp down to 1 ohm and have it about a 1/4 of the way turned up on the amps gain. this amp really puts out some powe. now i am sure its not 4000 rms. it does seem to push about 2000-2500 rms at 1 ohm because my sunbs are really being pushed to the max and they are really flexing. the amp is very sleek and very beautiful. i love that it has a fan built in and even wired at 1 ohm being pushed for over an hour on a road trip it did not turn off due to heat. i havent had a single problem with this amp. i would highly recommend this amp for subs that require serious power. i have been into cardio for years and i believe this amp can push a sundown,w6,w7, kicker l7,and fi subs. if you buy this amp i promise it will not disappoint you and can handle almost anything you throw at it. make sure you upgrade your stock battery and add atleast a 4 farad cap. hope this review helps anyone who is on the edge about buying this amp!!

This amp absolutely blew me away I have it connected to a 2009 Version Memphis quad coil 15" subwoofer and I can't turn it even halfway up on the levels of the amp. Beats the hell out of my car. I plan on changing my entire setup later to 4-12" subs but i am torn between RE, Memphis and The Champion series Pioneer subs. I recommend this to anyone on a budget and wants some true BANG!!!!

Superb Budget Amp

October 9, 2014

I bought this a month ago to power my 12" Fi BL sub rated at 1500 watts RMS. This amp certainly does 1500, even with the gain matched properly (about 1/4), I need to significantly reduce the sub level to reduce the power to a reasonable level for the beast Fi BL. Does this amp do 4000 watts? No, I expect it does 2000 - 2200 - which is incredible for $240. Does it live up to the BB name? Yes, it is like a smaller, more aesthetic BB2400.1. Still a fan of Big Bang amp series!

Great amp

June 20, 2014

I purchased this amp as a alternative to the hifonics that was on back order. Let me say I am glad I did. It has plenty of power to run my eight Sundown Audio e8v3d4 subs at 1 ohm. The crossover control is great too. The cosmetics of the amp is a 10/10. They remind me of the old US Amps from the mid to late '90s. The blue logo that lights up looks great too. It's not too flashy or cheap looking and isn't excessively bright. I would buy this amp again and I would recommend it to friends or prospective buyers. This is my first planet audio amp ever. The only thing that would make me happier about it is if it was built by ZED audio like the old planet audio amps.

I've only had the amp 1 month and have had zero issues with it. Durability will come with time!

Definitely worth it!

September 17, 2013

I have this amp hooked up to two Alpine Type R 12's. I drive a Mark 4 Jetta, and my car slams.
This amp pumps out a lot of power, perfect for a great system. I strongly recommend this amp, couldn't have asked for anything better.

Big Bang for the Buck!

May 31, 2014

I chose this amp after the other brand I ordered was out of stock and I'm glad I did. Cosmetically it is beautiful and the power output is great. I'm running eight sundown audio e8v3d4's running at 1ohm and it pounds. I would recommend this amp to anyone.

Well worth it!!!

March 15, 2014

This Big Bang series is insane, I have one hooked up to 4 15inch kicker cvr and I hit 146.7 db. All my gains are low and I have to update my deck. I'm running 4 gauge wire,stock battery,stock alternator. I'm definitely ordering another amp and upgrading to zero gauge wire and doin the big three. For the price well worth it, see u soon sonic!!!!!!

Tuscaloosa, AL

pleasantly surprised

April 10, 2014

I bought this a month ago and let me tell you this is by far one of the best amps I've ever purchased, it puts it just like it says not a true 3000 watts but definitely 2500 watts and you can't be the price picks up good lows, I suggest doing the big 3 to be safe can be a little power hungry but definitely worth the price, like the internal cooling fan, would purchase again!

Looking for a good amp.
Justin L on Aug 15, 2014
to try it out as a budget amp the older big bang were great hopefully this one will be too we will find out soon enough
Clinton on Sep 16, 2014
is this amp anything like the older big bang series amps like the bb2400.1? Also do they do near rated power?
Clinton on Sep 7, 2014
Best Answer: I did a lot of research before I bought this amp and I haven't had any problems with it. The power draw is pretty high so be sure you have good wiring. I also added a secondary battery. I had a 3000 rms amp on my subs before and have gotten a lot louder now so the power output is good.
