Belva Slappin' Bass Packs

The newest addition to the Belva line-up is an entire series of complete bass packages! These loaded enclosures also include an amplifier, and wiring to make sure you're supplied with everything you need to add bass to your vehicle. Belva added these loaded ported enclosures to their line-up in an attempt to revitalize the car audio industry with quality bass at an affordable price, and making the process easier than ever before.

As soon as you receive your new bass package, installation is a 4-step process. First - make power connections. Second - make signal connections. Third - connect subs. Fourth - tune the amplifier and enjoy your new bass system. Installation of a subwoofer package has never been so easy!

The wiring included with the package is completely true to gauge so the amplifier can perform at its very best. The quality of the wiring is very high for such an affordable kit. The subwoofers are also loaded into a ported enclosure. These ported enclosures allow for the system to be much more efficient - giving you more bass output per watt.

Not only is the installation easy, but the value of quality bass per dollar is second to none. These systems are one of the most amazing deals we've ever been able to offer at This BPKG210 includes two 10" subwoofers enclosed in a ported box, a monoblock amplifier to drive it, and a complete 8 gauge amplifier kit to wire the system up. A remote bass knob & high level inputs are included for compatibility with any system - and remote bass adjustments allow you to tune the bass to your liking on the fly.

Amplifier Power Specifications

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.
250 watts x 1 channels

Amplifier Specifications

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 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.

250 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.
2 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.
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.
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)
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.
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.


Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.

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.
250 watts
Total RMS Power Handling
This is the total RMS power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total RMS power handling for all of the subs combined.

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 giving your subwoofer(s) 75% - 90% of the recommended RMS rating.
500 watts
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
500 watts
Total Peak Power Handling
This is the Total Peak Power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total peak power handling for all of the subs combined.

Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements.

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.
Vented / Ported
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
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
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
Box Exterior Color
The color of the enclosure's exterior/outer finish.
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.

Definitely a really good budget system!

October 28, 2016

I am very satisfied with this system. It's more than I expected from a $150 subs.

This system even hits decent lows. Shakes my seats and windshield. I would definitely recommend this to people who want to add bass to their car and still be able to turn it up good! Very good purchase for kids in school too. Just keep in mind these are not able to compete with better systems. The amp gets pretty warm, almost hot but hasn't failed me. Subs stay cool even through a 1 hour drive bumping them to their limits the entire way..still very cool to the touch.

Again I highly recommend this to kids in school or people who want trunk space and more bass in their system.

Only complaints would be the amp gets pretty warm and I don't really like the bass knob. OTHER than that I really enjoy this!

Belva BPKG210v2 Amplified bass package

October 24, 2016

Having spent 30 years in the aftermarket audio field,as a professional installer/tech,made me want to try something other than product I was already familiar with.I was curious to see just what Belva was about.That being said,dollar for dollar,you won't really find any better deal than this when it comes to eveything you get.A complete,amplified subwoofer system,with everything it takes to install it into virtually any vehicle it will fit into at this price point. I will say,the enclosure is well made,with internal bracing,and a front facial laminated board so that the subs look like they are flushed in,as well as being nicely trimmed out with durable "speaker box" material.It's a very nice looking set up overall.I will say,the box is just a little too small for these woofers,and the amplifier could have been a bit stronger than it is,BUT,it does sound very good overall,and performs rock solid.I haven't heard,or have seen any other package deals in this price range that would give it a run for the money,and there are several out there.I'm just not too sure of the quality of the build of other products being up to par with this deal.

What a great deal for the money

October 18, 2016

This bass package was just what the doctor recommended for my van , just the rite amount of bass and doesn't draw to much attention to our van . My 8 and 10 year old daughters LOVE the feel of the bass and want to tell all their friends about it , but Dad said if we want to keep our system you cant tell all your friends Dad even installed an alarm system to insure we keep it !!! This system is so awesome for the money , came with everything you need to do the install and all that is left is the enjoyment of it . Great bang for the buck !!!!

Great Low Cost Option

August 16, 2016

I was looking to get some bass in my ride, but I was also on a limited budget. The Belva kit gave me everything I needed to get bass back in my life, and was at a great price. Have friends that bought the other packages that are similar to the Belva package, and they have now bought the Belva package after they heard mine. Great bang for the buck!

Alot better than I expected!

March 2, 2016

This was alot better than I originally thought it would be. All pros, one small con.... The ring terminals they send with the set are too small to ever go on a battery terminal and that forced me to use the included zip ties to make it work.. It's fine for Now but I'll need to go buy a new ring terminal to use

Will this fit in a 2010 Chevy Cobalt sedan??
A shopper on May 7, 2017
Best Answer: It's... to my understanding... designed to fit behind the seat in a regular pick up truck... there's not a lot of room behind that seat... I have not installed mine as of yet... but it is wedge shaped and appears that it will fit... I'm not sure where you intend to mount it in your Cobalt... but you can view the demensions on line and then with tape measure in hand... check out the space you intend to place it in... I'm guessing it will work...

What kind of amp would be an upgrade to the one that comes with the package? One that would still match with the subs. The amp that came with it is under powered for me.
Jwalker2 on Feb 26, 2017
Best Answer: Before you waste your money on another amp, check your settings on your amp. The frequency setting should be between 80 - 120 Hz. The bass boost turned all the way up and use the remote that came with the amp. If you know the preamp voltage of your head unit set your gain on your amp the same. Remember that it is a ported box, it will be loud but not tight. Good luck.
