Shallow Mount Subwoofer Buying Guide
These 10 subwoofers are the best of the bunch, and whatever your personal set-up, we’re confident you’ll find something on our list that fits the bill. To help you choose, we’ve compiled this brief guide. Below we run through what to look out for when selecting a shallow mount subwoofer for your vehicle, why you might want one, and how to get started.
What to Look for in a Shallow Mount Subwoofer
When it’s time to choose a slimline subwoofer for your vehicle, watch out for the following features:
- Slim Design
Shallow mount subwoofers are meant to be just that – shallow. When shopping for one of these speakers, make sure it’s slim enough to fit into its proposed space. Most of these subwoofers measure somewhere between 3.25 and 3.5 inches in depth, which is usually slim enough for most automotive applications. If in doubt, carefully measure your planned installation space before making your final decision.
- High Quality Cone
A subwoofer’s cone is one of the most important elements, so it’s important to make sure that it’s made to a high standard of quality. Anodized aluminum, mica-injected resin, and carbon fiber are three of the best materials to look out for. Because they’re strong and rigid, they help to produce an accurate sound.
Nobody wants to install their new speaker only to have it give out after just a few uses. For this reason, it’s important to choose a slimline subwoofer that can stand up to regular use. It can be hard to tell how long a component will last by description alone, so check out reviews from other customers if possible. Stitched tinsel leads and a good quality cone also imply that a subwoofer is built to last.
If you’re a dab hand at audio systems, you might want to choose a subwoofer that can be installed in multiple ways. If this is the case, look out for a device with dual 2 or 4-Ohm coils.
- Cooling System
A good shallow mount subwoofer won’t overheat during use. To make sure your new component won’t run too hot, watch out for a good venting system. Many slimline subwoofers use the same spider venting as their larger cousins.
Benefits of Shallow Mount Subwoofers
Adding a shallow mount subwoofer to your sound system comes with a whole host of benefits:
- Compact, slimline subwoofers are more affordable than their conventional counterparts
- Shallow mount subwoofers don’t take up much space in your vehicle
- Adding a slimline subwoofer to your sound system significantly improves sound quality
- Shallow subwoofers come in a few different sizes, so it’s easy to find the right fit
- Subwoofers provide a crisp, clear sound
- Shallow mount subwoofers help drivers rediscover their favorite music
- Many slim subwoofers offer a comparable performance to traditional designs
How to Install a Shallow Mount Subwoofer
With a little electronic know-how, you can install a shallow mount subwoofer in your vehicle at home.
Although different models may vary, you can expect to work through the following steps when installing a subwoofer in the trunk.
- A subwoofer box
- The subwoofer itself
- Wiring kit
- Basic toolkit
First, you’ll need to run power from the vehicle’s battery. Find an opening in the car’s firewall (the metal wall under its hood, near the windshield) and run most of a power cable through the hole.
Strip the insulation away from the wire at the battery end, and wire the in-line fuse to this end. Don’t connect the wire to the battery at this point.
Next, run the remaining length of power cable under the car’s carpeting, all the way to the trunk. While the carpet is loose, run a 16-18 gauge wire and two RCA cables from the trunk to the back of the stereo head.
Remove the stereo head unit, and look at its back. You should see two RCA connections, each of which should be connected to your RCA cables.
The 16-18 gauge wire must also be connected to the stereo – the appropriate wire will be labelled ‘Amp’ or ‘Amplifier’. This ensures the amplifier comes on when the stereo does.
Once this wiring is completed, place the subwoofer in its box, and secure it as appropriate. Set the box in the trunk of the car.
Next, you’ll need to wire up the amp, by connecting the power cable (from the car’s battery) into a port with one of these markings:
Connect your 16-18 gauge wire into the port reading:
Ground the system by connecting a three foot, 10 gauge wire to the place marked:
And, finally, connect the other end of the ground wire to a bolt that meets the car’s body.
Next, connect the speaker wire to the + and – speaker ports on the amplifier. Connect the other end of these wires to the + and – ports on the subwoofer itself.
Return to the battery, connect it to the power cable, and you’re done.
When installing a shallow mount subwoofer, you’ll have a few different placement options. If your vehicle has a rear speaker deck, placing the device here may be a better idea. With the subwoofer in this position, you’ll be better able to hear the bass sounds produced.
Although it’s often easier to position a subwoofer in the trunk, here you’ll feel the bass as much as hear it, and a lot of sound will be lost to the outside world.
If in doubt, may workshops will be able to install your new subwoofers for you.
Best Shallow Mount Subwoofer FAQ:
Q: What is a shallow mount subwoofer?
Subwoofers are a special type of speaker, specifically designed to produce low frequency sounds between 20 and 80 Hertz, otherwise known as bass. Inside a subwoofer, electrical signals are passed through a magnetic coil that causes a cone to vibrate. We perceive these vibrations as low pitched sounds. Subwoofers are a useful piece of kit if you want to experience a ‘beefier’ range of sound. However, they should be combined with other speakers for best results. In terms of practicality, one key difference between regular speakers and subwoofers is that the latter requires an external power source. Slimline, or shallow mount subwoofers work by the same principles as their conventional brethren, and produce the same frequencies. However, they are much slimmer, allowing them to be fitted in tighter spots, such as vehicle interiors.
Q: What size of shallow mount subwoofer should I pick?
This really depends upon how much room you have in your vehicle, and how much you want to spend. This type of speaker ranges in size from eight to 15 inches – larger options tend to be pricier, but they do offer a wider range of low frequencies.
Q: How do they compare to regular subwoofers?
Although shallow mount subwoofers function through the same principles as regular versions, they do differ in a few key ways:
- Slimline subwoofers consume less power
- Slimline subwoofers are more affordable
- Slimline subwoofers take up significantly less space
- Regular subwoofers produce a greater range of low frequencies
