Best Spare Tire Sub - Buyer’s Guide

Drawing from our experience when you’re in the market for the top spare tire sub, you’re looking at a unique niche of audio equipment. Spare tire subwoofers aren't just a gadget you pick up on a whim, they are a statement - a commitment to superior audio quality without sacrificing space.

Let’s dive deep into the considerations that are paramount when choosing the best spare tire speaker(sub) for your ride:

Space and Compatibility

The first question you need to ask is: will the subwoofer fit? Measure your spare tire compartment meticulously, noting the width and depth. Most spare tire subwoofers are designed to universally fit standard spare tire wells, but it’s always better to be sure. Compatibility is not just about dimensions; it’s also about acoustics. A spare tire subwoofer should harmonize with your car’s acoustics to enhance, not overpower, the listening experience.

Power and Sensitivity

Wattage is not just a number, it’s about how it translates to sound. Consider RMS (continuous power handling) over peak power. RMS gives you a clear idea of how powerful your spare tire subwoofer will be on a regular basis. Sensitivity, measured in decibels (dB), is also crucial. A higher sensitivity rating means more sound from less power, which is especially important in the confined space of a spare tire well.

Sound Quality

The core purpose of a spare tire subwoofer is to deliver deep and precise bass. Look for features like built-in amplifiers, high-quality cone materials, and advanced sound technologies that ensure clarity at all volume levels. Distortion should be minimal, and the sound should be pure, regardless of how loud you like your music.

Connectivity and Integration

In the modern age, connectivity is key. Your spare tire subwoofer should seamlessly integrate with your existing audio system. Whether it's through simple RCA inputs or high-level speaker inputs, ensure that the subwoofer you choose can connect easily with the equipment you already have.

Durability and Build Quality

Your spare tire subwoofer is going to be in a place that might see a lot of movement and possibly even moisture. Look for a subwoofer with a sturdy build and materials that resist corrosion and wear. Features like rubber surrounds and treated cones add to longevity.

Additional Features

Consider if you want a passive or active spare tire subwoofer. An active subwoofer has a built-in amplifier, which simplifies installation and usage. Look also for subwoofers that offer remote controls for bass level adjustment and other settings that can enhance user experience.

Brand and Warranty

A reputable brand often means a quality product and customer service. Check the warranty and support options. A longer warranty can be a sign of the manufacturer's confidence in their product.
