Best Cheap Car Subwoofers Series [under $50 & $100]

Home » Car Subwoofers » Best Cheap Car Subwoofers Series [under $50 & $100]

If you’re looking for budget subs with size options, your best bet is to go with the Rockville or Skar Audio models. They are affordable, have a good power range which goes to a maximum of 5,000 watts, something that few others can’t offer. These subs are stable, lightweight, work efficiently, and can handle the heat.

But if you want to fall back on a brand name the Rockford Fosgate P1 series will suit you well. They are made for low distortion and high output and there are many size options. The peak handling is not as good as Rockville but these subs are efficient, durable, and compatible with a range of amplifiers.

Available sizes: 8-inch, 10-inch, 12-inch

Power (in watts RMS): 150 (8”), 200 (10”), 250 (12”)
Price: All under $55

The IX subwoofer series has three variants—8 inches, 10 inches and 12 inches. The Skar Audio claims that these are the most powerful and reliable drivers while also being affordable. If you are looking for a budget model subwoofer that is perfect for your car, you definitely want to check these out.

All of them come with a single slug premium ferrite magnet which helps it perform at peak levels safely for a good period of time. The subwoofers also come with a two-inch BASV voice coil which allows for optimal performance and cooling.

This is of high quality and is the feature that essentially keeps this woofer line in the running for some of the most powerful subwoofers in its class. They also come with an option of 2 ohms or 4 ohms.

The IX series subwoofers are a terrific combination of efficiency and reliability whether you plan to use them in a sealed application or a vented one. The rating is conservative and the drivers are assembled using components made of the highest grade. This is precisely what separates it from the rest of the competition.

The 8-inch subwoofer (more options) has a maximum power of 150 watts RMS with a maximum handling capacity of 300 watts. The 10-inch variant is rated at 200 watts RMS and a maximum of 400 watts. Lastly, the 12-inch subwoofers come with 250 watts RMS with a maximum power capacity of 500 watts.

All the subwoofers in the series also have an advanced cooling system. These products also have a high roll foam surround and premium strength paper cone which makes the driver quite versatile. If there is a con to these products, it is that some users have reported a little disappointment in its frequency range.

Power (in watts RMS): 250 (6.5”), 500 (8”), 800 (10”), 1000 (12”), 1250 (15”)
Price: All under $140

If you ask us what are the best budget subs given the price, specs, materials, and size availability, the answer would be Rockville K9 series subs. You’ll be paying around $140 for the biggest 15″ option, everything else is cheaper.

These subwoofers have an RMS power range of 250 watts to 1,250 watts with a peak power range of 1,000 watts to 5,000 watts – NO ONE COMES NEAR THESE NUMBERS (give the price). All the models come in 2-ohm and 4-ohm options.

The subwoofers also have two-inch, four-layer ASV voice coils that are wound with oxygen-free copper (OFC) wire that is made in the USA which makes the subwoofer stable.

Each of them also comes with a high-quality magnet and a cast aluminum basket with a finish that makes it efficient and lightweight. There are two chrome-plated post terminals that are the best in the market and can accept wires of any gauge.

They have a non-pressed paper-cone finish which makes them very stiff. The cone comes with reinforcements that make sure the sub runs for a long time. Additionally, there is a polypropylene dust cap.

The subwoofers can also handle a lot of power because they are thicker and stronger than most other subs in the market. The incredible sound quality comes from the thick foam surround and there is minimal distortion too. The heat is managed well as it is dissipated from a vented hole.

Another nice affordable option from Rockville comes in form of K6 series subs. These subs come with an RMS power capacity range from 500 to 1,000 watts. And their peak power handling ranges from 2,000 watts to 4,000 watts.

Each of the subs comes with a high-quality magnet that is double stacked and weighs 100 ounces. The aluminum basket has a black sanded finish which makes the sub efficient.

The non-pressed paper cone is reinforced with fiber and has a polypropylene dust cap. The exceptional sound quality comes from the thick foam surround. There are custom-made rubber boot magnets that make the woofer look good while protecting the magnet. It is also why the sub is easy to mount.

Available sizes: 8-inch, 10-inch, 12-inch

Power (in watts RMS): 400 (8”), 500 (10” and 12”)
Price: All under $100

Our second recommendation is also from Skar Audio. First, let’s talk about the VD series which is a range of shallow mount subwoofers. It is best used in applications with a limitation on depth.

However, power and sound are left uncompromised. These subwoofers have a two-inch voice coil with a high-temperature range. There is a low-profile single stack ferrite magnet which makes it possible to handle a good deal of power while keeping the footprint shallow which makes their application quite versatile.

The 8-inch subwoofer has 400 watts RMS power handling with a maximum capacity of 600 watts. The 10-inch (more options) and 12-inch models come with 500 watts RMS and have a maximum handling capacity of 800 watts. All of them come with a dual 2-ohm capacity.

Sound Ordnance M2 Series

Available sizes: 8-inch, 10-inch,

Power (in watts RMS): 50-150 (8” and 10”), 50-250 (12”)
Price: Under $70

The selling point for this budget subwoofer series from Sound Ordnance is that it adds “some boom to your ride”. To begin with, there are three variants in the M2 series—8, 10 and 12 inches and they are all conveniently priced.

You can add more than one of them to your car if you want a little extra bass without burning a hole through your pocket. The subs are made of a tough glass fiber cone which keeps its shape and bass intact even when the volume is turned up.

They all also come with a butyl rubber surround sound which promises to keep the woofer movement on point for many years. The subs come in a steel basket which is a nice, little enclosure for the device.

The 8-inch model has a peak power capacity of 300 watts as does the 10-inch while the 12-inch model goes up to 500 watts. The 10-inch model comes with a dual 4-ohm voice coil so it gives you more stability while you play your music out loud.

Also Great

Kicker CompR Series

Available sizes: 8-inch, 10-inch, 12-inch, 15-inch

Power (in watts RMS): 300 (8”), 400 (10”), 500 (12”), 800 (15”)
Price: All under $150 except 15″ option

If you are looking for budget subs, you might want to check out the 8- and 10-inch models. But the entire series has four models. These subs are sold by the Kicker as powerful and reliable. If you like your music loud and for a long time, you might like the Kicker CompR series.

The 8-inch model has a power capacity of 300 watts RMS with a peak capacity of 600 watts. The 10-inch sub has a power of 400 watts RMS and its maximum is 800 watts.

Now, all the subs have a double-stacked magnet and a powerful bass and there is a low-end response for thump. This series also comes with a signature red double stitching which makes the woofer cone and surround sound bond well which means the bass stays deep at all volumes.

All the CompR subwoofers also come with a suspension system that has a large diameter to eliminate distortion and accommodate linear movement.

Now about the heat. There is a forced-air cooling system that keeps the subs 25 percent cooler than the previous models from the same manufacturer. All the subs in this series come with two sets of coils that have brass terminals. They are spring-loaded and come with a satin nickel finish. Gently push the terminal and you will get the wiring options.

MTX Terminator Series

Available sizes: 10-inch, 12-inch

Power (in watts RMS): 150 (10”), 200 (12”)
Price: under $70

Here is another economically priced subwoofer series. This is the Terminator series from MTX. This series has two variants—10 inches and 12 inches. While the 10-inch model only has dual 2-ohm voice coils, the 12-inch model comes with an option of 4-ohm coils too.

The subs in this series are the pride of MTX engineers because of two main features. The devices have a spider plateau venting which cools the coils and keeps them from overheating. The second is the linear drive system which is asymmetrical and makes the cone move only in the linear direction and prevents distortion.

The venting technique also keeps the performance levels of the subs top-notch. For a budget subwoofer, this series has a lot to offer. It is described as a “badass pounder” which has an extended pole piece too. This makes the output smooth and piston-like drive.

The subs are also equipped with rubber surround sound, which makes them more durable and keeps them working for a long time.

The 12-inch model is known to give you bass in any rig and is labeled the classic Terminator. It is an entry-level sub but is touted to be better than every other model in its class and offers great performance. It has a single voice coil and has all the features that the 10-inch model does.

Here’s an interesting fact, these subwoofers are actually turned by some of the expert engineers in the business so that the output is a signature JBL sound. Something the manufacturer is quite proud of.

All the speakers are rigorously tested to make sure the efficiency and durability of the product are not compromised after purchase. This includes testing them in a variety of climatic scenarios. The products are frozen, baked, and shaken vigorously. They are also subjected to a blast of UV rays and are played at high power for days to make sure the product lives up to the promise.
