Subwoofer Equipment Costs

The Subwoofer

Subwoofers come in various sizes, qualities, and power ratings. Here’s what you can expect to pay:

• Budget subwoofers ($50-$150): These entry-level options provide basic bass enhancement without breaking the bank. They typically handle 100-300 watts RMS and work well for casual listeners.
• Mid-range subwoofers ($150-$300): These offer better sound quality, durability, and power handling (300-600 watts RMS). Brands like JL Audio, Kicker, Rockford Fosgate, and Alpine fall into this category.
• Premium subwoofers ($300-$600+): High-end subwoofers deliver exceptional sound quality, can handle 600+ watts RMS, and are built with superior materials for optimal performance and longevity.

The size of your subwoofer—typically 8, 10, 12, or 15 inches—also affects the price. Larger subwoofers cost more but can produce deeper bass.

Amplifiers

Your subwoofer needs an amplifier to power it properly. Amplifier costs include:

• Budget amplifiers ($60-$150): Basic mono amplifiers that put out 300-500 watts RMS.
• Mid-range amplifiers ($150-$250): Better quality amps with 500-1000 watts RMS and features like subsonic filters and bass boost controls.
• High-end amplifiers ($250-$600+): Premium amps with 1000+ watts RMS, advanced cooling systems, and audiophile-grade components.

Make sure your amplifier’s power output matches your subwoofer’s requirements. An underpowered sub won’t perform well, while too much power can damage it.

Subwoofer Enclosures

The box that houses your subwoofer plays a crucial role in sound quality. Your options include:

• Pre-made enclosures ($30-$150): Generic boxes designed for specific subwoofer sizes.
• Vehicle-specific enclosures ($100-$200): Boxes designed to fit particular vehicles while maximizing available space.
• Custom-built enclosures ($150-$400+): Tailored to your exact specifications and vehicle dimensions for optimal performance.

The enclosure type—sealed, ported, or bandpass—affects both price and sound characteristics.

Wiring Kits

A proper wiring kit is essential for a safe, high-performing subwoofer installation:

• Basic wiring kits ($20-$50): Include the minimum necessary cables and connectors for a simple setup.
• Complete wiring kits ($50-$100): Higher quality wires with better conductivity, fuse holders, remote turn-on wire, and all necessary connectors.

When choosing a wiring kit, consider the gauge (thickness) of the power wire. For systems under 500 watts, 8-gauge wire works well. Systems between 500-1000 watts need 4-gauge, while anything over 1000 watts should use 0-gauge wire.

Professional Installation vs. DIY

Professional Installation Costs

Having a professional install your subwoofer system costs between $50 and $250, depending on:

• The complexity of your audio system
• Your vehicle make and model
• Local labor rates

Professional installation often includes:

• Proper mounting of the subwoofer and enclosure
• Secure installation of the amplifier
• Running power wire from the battery
• Installing a fuse near the battery
• Connecting the remote turn-on wire
• Running RCA cables
• Setting up gain and crossover settings
• Testing the system

Many car audio shops offer installation packages or discounted labor when you purchase equipment from them. Some shops charge a flat rate, while others bill by the hour ($75-$150 per hour).

DIY Installation: Costs and Considerations

If you’re handy with tools and have basic knowledge of car electronics, you can install a subwoofer yourself. DIY installation costs include:

• Tools ($25-$100): Wire strippers, crimpers, screwdrivers, drill bits
• Additional materials ($15-$50): Wire ties, electrical tape, sound dampening materials
• Your time: Expect to spend 3-8 hours on installation

The main benefit of DIY is saving on labor costs. However, mistakes during installation can damage your equipment or even your vehicle’s electrical system. Professional installers also guarantee their work, which provides peace of mind.

Additional Costs to Consider

Sound Deadening Materials

Adding sound dampening materials ($30-$100) to your doors, trunk, or cargo area reduces vibrations and improves bass response. This step isn’t strictly necessary but can significantly enhance your listening experience.

Line Output Converter

If your factory stereo doesn’t have preamp outputs, you’ll need a line output converter ($15-$80) to connect your amplifier to the factory system.

Capacitors

For high-powered systems, a capacitor ($30-$150) helps stabilize voltage during bass hits that demand large amounts of current, preventing your lights from dimming.

Upgraded Alternator or Battery

Very powerful systems might require electrical system upgrades:

• High-output alternator: $200-$500+
• Additional battery: $100-$300

Custom Fabrication

Custom work like fiberglass enclosures, custom panels, or integrated designs can add $200-$1000+ to your installation cost.

Cost Factors That Impact Subwoofer Installation

Vehicle Type

Your vehicle make and model significantly impact installation costs:
