My Buying Guides on Under Seat Subwoofer With Built In Amplifier
When I decided to upgrade my car audio system, I quickly realized the importance of a subwoofer. After some research, I found that under seat subwoofers with built-in amplifiers were a perfect fit for my needs. They provide deep bass without taking up too much space. Here’s my comprehensive buying guide to help you find the right one.
Understanding the Basics
What is an Under Seat Subwoofer?
An under seat subwoofer is a compact subwoofer designed to fit under the seats of your vehicle. These units are great for enhancing bass response without sacrificing precious space in your car.
Why Choose One with a Built-in Amplifier?
Having a built-in amplifier means I don’t need to worry about additional components cluttering my car. It simplifies installation and saves space, which is perfect for my needs.
Factors to Consider
1. Size and Fit
I always recommend measuring the space under your seat before making a purchase. Most under seat subwoofers are designed to be compact, but it’s crucial to ensure it fits comfortably without interfering with seat movement or comfort.
2. Power Output
Look for a subwoofer with adequate power output, usually measured in watts RMS. I found that units with at least 100-200 watts RMS deliver a satisfying bass experience without distortion.
3. Frequency Response
The frequency range of the subwoofer is essential. A good subwoofer should have a low-end response that reaches below 30 Hz. This ensures that you can feel the bass in your music, which is something I always appreciate during my drives.
4. Build Quality
I’ve learned that durability matters. Look for a well-constructed unit with quality materials that can withstand the vibrations and conditions of a vehicle. A sturdy enclosure helps in producing better sound quality.
5. Connectivity Options
Consider how you’ll connect the subwoofer to your audio system. Many models offer multiple connection options like high-level inputs for factory systems and low-level inputs for aftermarket setups. I found this flexibility extremely helpful during installation.
6. Ease of Installation
Some under seat subwoofers are designed for easy installation, often including mounting hardware and wiring kits. If you’re not a DIY enthusiast, I suggest looking for a model that comes with clear instructions or consider professional installation.
Additional Features to Look For
1. Adjustable Bass Control
Having the ability to adjust the bass level is a feature I found invaluable. This way, I can tweak the sound according to my music preferences or the genre I’m listening to.
2. Built-in Protection Features
I always look for models with built-in protection against overheating and overloading. This feature extends the lifespan of the subwoofer and ensures consistent performance.
3. Remote Control
A remote control adds convenience, allowing me to adjust settings without having to reach under the seat.
