Buying Guide: What to Look For in a 9-Inch Subwoofer for Your Honda Ridgeline Back Seat
When I decided to add a subwoofer to my Honda Ridgeline, I knew the back seat was the perfect spot. It’s a protected, space-efficient location that doesn’t sacrifice the utility of the truck bed. But not all 9-inch subwoofers are created equal, and the unique environment of a truck cabin demands specific features. Here’s what I learned to focus on during my search.
First, you need to think about the type of enclosure. For the back seat, you’re almost always looking at a pre-built, powered subwoofer or a custom shallow-mount setup in a slim box. A powered sub, like one from Rockford Fosgate or Kicker, is a fantastic all-in-one solution. It comes with its own built-in amplifier, so you just need to run power and signal wires. This is a huge time-saver. The alternative is a component subwoofer, which requires a separate external amp. This gives you more power and customization potential, but it’s a more complex installation. For most of us, the convenience of a powered unit is the way to go.
Next, consider the power handling. Look at the RMS wattage, not the peak power. A subwoofer with a higher RMS rating, paired with a robust built-in amp, will deliver cleaner and more impactful bass, especially when the engine is running. Since the Ridgeline’s cabin is a relatively small space, you don’t need a massive amount of power to make a big difference. A unit with 150-300 watts RMS is more than enough to fill the cabin with deep, clear bass without overwhelming everything else.
Finally, pay close attention to the physical dimensions. The space under the Ridgeline’s rear seats is limited in height. You must measure the available clearance carefully before you buy. This is why shallow-mount subwoofers are so popular for this application. They are designed with a smaller mounting depth, allowing them to fit into tight spaces where a traditional subwoofer would never go. A slim, compact design ensures a seamless installation that doesn’t require you to modify or lift the seat. Getting the right fit is the most important step in choosing the best 9 inch subwoofers for a Honda Ridgeline back seat.
FAQ
Is it difficult to install a subwoofer under the back seat myself?
It depends on your comfort level with car audio projects. Installing a powered all-in-one subwoofer is a very manageable DIY job. The main tasks are running a power cable from the battery through the firewall, finding a good ground point, and tapping into your factory head unit for an audio signal. If you’re using a component sub and separate amp, the complexity increases. There are many good tutorials online specific to the Honda Ridgeline that can guide you through the process. If you’re not confident with wiring, having a professional do the installation is a smart investment.
Will a 9-inch subwoofer be powerful enough for my truck?
Absolutely. A 9-inch subwoofer is an excellent size for the cabin of a Honda Ridgeline. The interior of a truck is a smaller, more enclosed space compared to a large SUV or sedan trunk. This means you don’t need a gigantic 12-inch or 15-inch sub to feel the bass. A well-designed 9-inch sub, especially one with adequate RMS power, will produce a surprising amount of clean, punchy bass that complements your door speakers perfectly. It fills out the low end you’re missing without being overkill.
Do I need to upgrade my factory stereo or speakers?
Not necessarily. Most powered subwoofers have high-level inputs, which means you can connect them directly to the wires going to your factory speakers. This allows the sub to work with your stock stereo. However, if your Ridgeline has a premium factory system, you might need a special interface to convert the signal properly. As for your other speakers, adding a subwoofer actually takes the strain off of them, as they no longer have to struggle to produce low bass notes. This often makes your entire factory system sound clearer and louder.
How much space do I actually have under the seat?
The space under the rear seat of a Honda Ridgeline is generous in terms of width, but the height is the main limiting factor. You typically have between 4 to 6 inches of vertical clearance, depending on the model year and the specific spot you’re measuring. This is why you must get a tape measure and check the exact dimensions before purchasing any subwoofer or enclosure. This measurement will immediately tell you if a particular model will fit or if you need to look for a slimmer, shallow-mount option.
Can I still use the underseat storage with a subwoofer installed?
This is a key consideration. Most custom enclosures and some pre-built powered subwoofers are designed to sit on the floor, potentially blocking access to the in-floor storage bins. However, many models are built with a low-profile design that tucks neatly under the seat frame, preserving that valuable storage space. When you are shopping, look specifically for models that advertise a “slim” or “low-profile” design and check user reviews to see if other Ridgeline owners confirm that the storage remains usable.
