Getting Started: Prep Work for Your Kicker Speaker Installation
Before you even think about popping off a door panel, a successful installation begins with proper preparation. From my years of experience in the garage, I can tell you that having the right tools and parts laid out beforehand turns a frustrating afternoon into a rewarding project. This initial phase is all about making the actual installation process smooth and efficient.
Essential Tools and Materials
Gathering your tools first is non-negotiable. Scrambling to find a screwdriver mid-install is a recipe for lost screws and scratched panels. Here’s a checklist of what I keep in my own toolbox for a standard speaker swap.
- Panel Removal Tool Kit: This is my number one recommendation. A set of plastic pry tools is crucial for removing door panels without scratching paint or breaking delicate clips. Do not use a flathead screwdriver.
- Screwdriver Set: You’ll need both Phillips head and flathead drivers in various sizes. A magnetic tip is a lifesaver for not dropping screws inside the door frame.
- Socket/Wrench Set: Many factory speakers are held in with bolts, often 8mm or 10mm.
- Wire Strippers/Cutters: Essential if you choose to splice wires instead of using an adapter.
- Wire Crimpers & Connectors: For creating secure, lasting connections.
- Drill with Phillips Head and various drill bits: This is often necessary for mounting the new speaker, especially if you need to use a speaker adapter bracket.
- Speaker Wiring Harness Adapter: This is a small adapter that plugs into your car’s factory speaker connector on one end and has terminals for your new Kicker speaker on the other. I strongly advise using these to avoid cutting factory wiring.
- Speaker Adapter Brackets: Most factory speakers aren’t a standard 6.5″ screw pattern. These plastic or MDF rings allow you to mount your new Kicker 6.5 speakers securely in the factory location.
- Sound Deadening Material (Optional but Recommended): A product like Dynamat or Kilmat applied to the metal door panel behind the speaker dramatically improves bass response and reduces rattling.
Choosing the Right Kicker 6.5″ Speakers
Kicker offers a fantastic range of speakers, and picking the right one depends on your goals and budget.
- Kicker CS Series: The most popular choice for a factory upgrade. They are efficient, sound great on stock radio power, and offer a massive improvement in clarity.
- Kicker KS Series: A step up in sound quality and power handling. These are a great choice if you plan on adding a small amplifier later for more volume and dynamics.
- Kicker QS Series: This is Kicker’s top-of-the-line, reference-grade series. These are designed for high-power systems with amplifiers and deliver true audiophile-level performance.
You’ll also see Coaxial vs. Component options. Coaxial speakers have the tweeter mounted in the center of the woofer, making for a simple, all-in-one installation. Component systems have a separate woofer and tweeter, which allows for better sound staging and imaging but requires a more complex installation. For this guide, we’ll focus on the more common coaxial speaker installation.
Safety First: Disconnect the Car Battery
Before you start, always disconnect the negative terminal of your car’s battery. Use a wrench (usually 10mm) to loosen the nut, then pull the cable off the terminal and secure it to the side so it can’t accidentally touch the post.
This prevents any accidental short circuits that could damage your car’s electrical system or your new speakers. It’s a simple step that I’ve seen countless DIYers skip, sometimes with costly consequences.
Step-by-Step Guide: How to Install Kicker 6.5 Speakers
Now for the fun part. We’ll break down the process of how to install kicker door speakers into manageable steps. We’ll use a common front door installation as our example, but the process is very similar for rear doors or side panels.
Step 1: Carefully Remove the Door Panel
This is often the most intimidating step, but it’s straightforward if you’re patient.
- Look for Screws: First, inspect the door panel for any visible screws. Common locations are in the door handle cup, the armrest pull-handle, and sometimes along the bottom edge of the panel.
- Pop Off Trim Pieces: Many of these screws are hidden behind small plastic covers. Use a small flathead screwdriver or your plastic pry tool to gently pop these covers off. The trim piece behind the side mirror is also a common removal point.
- Use Your Pry Tool: Once all screws are removed, start at the bottom of the door panel. Slide your plastic panel removal tool between the panel and the metal door frame until you feel it hit a clip.
- Gently Pry: Give the tool a gentle but firm twist to pop the clip loose. You’ll hear a “pop” sound. Don’t worry, this is normal. Work your way around the bottom and sides of the door, releasing each clip.
- Lift Up and Off: With all the clips released, the panel will be hanging from the top window sill. Lift the entire panel straight up a few inches to unhook it from the door.
- Disconnect Cables: Don’t pull the panel away yet! It will still be connected by the door handle cable and the electrical connectors for the window/lock switches. Carefully disconnect these. They usually have a small tab you need to press to release them.
Step 2: Access and Remove the Factory Speaker
With the panel off, you’ll see the factory speaker. It’s usually a lightweight paper cone unit held in by three or four screws or bolts.
- Unscrew the Speaker: Use your screwdriver or socket wrench to remove the mounting screws.
- Disconnect the Harness: The speaker will have a small plastic electrical connector on the back. Press the release tab and pull it off.
- Remove the Speaker: The old speaker can now be removed and set aside. I often take a moment to clean the mounting area with a rag to ensure the new speaker sits flush.
Step 3: Prepare the New Kicker Speaker Wiring
Proper wiring is critical for sound quality and speaker longevity. You have two options: using a harness adapter (highly recommended) or splicing the wires.
Method A: Using a Wiring Harness Adapter (The Easy Way)
- Take your speaker wiring harness adapter.
- Plug the plastic connector end directly into the factory speaker plug you just disconnected.
- The other end will have two metal terminals: one large (positive) and one small (negative).
- Connect these terminals to the corresponding tabs on your new Kicker speaker. It’s that simple! No cutting, no guessing.
Method B: Splicing Wires (The Hard Way)
If you don’t have an adapter, you’ll need to cut the factory plug off and connect the wires directly.
- Identify Polarity: You must determine which factory wire is positive (+) and which is negative (-). You can often find a wiring diagram for your specific car online. Getting polarity wrong will result in thin, weak bass.
- Cut and Strip: Cut the factory plug off. Use your wire strippers to remove about a half-inch of insulation from the end of each wire.
- Connect: Use crimp connectors (like butt connectors) to securely attach the positive factory wire to the positive terminal on the Kicker speaker, and the negative wire to the negative terminal.
- Insulate: Ensure no bare wire is exposed. I always wrap my connections with electrical tape for extra security.
Step 4: Mount Your New Kicker 6.5″ Speaker
Now it’s time to get the new speaker in place.
- Install the Adapter Bracket: If your car requires a speaker adapter bracket, secure it to the door first using either the factory speaker screws or new ones.
- Connect the Wires: Attach the speaker wires to the terminals on the back of your Kicker speaker.
- Position the Speaker: Place the speaker into the adapter bracket or the factory mounting hole.
- Secure the Speaker: Use the screws that came with your Kicker speakers to fasten it to the bracket/door. Tighten them in a star pattern to ensure the speaker is seated evenly, but don’t overtighten and risk cracking the frame.
The Pro-Tip: Add Sound Deadening
While you have the door panel off, this is the perfect time for an upgrade that makes a huge difference. Applying a sheet of sound deadening material to the metal of the door directly behind the speaker does two things:
- Reduces Vibrations: It stops the thin metal door from rattling and resonating, which cleans up muddy bass.
- Creates a Baffle: It helps create a more solid enclosure for the speaker, significantly improving mid-bass response.
From my experience, this is the single best “bang for your buck” addition to any Kicker speaker installation.
Testing and Reassembly: The Final Steps
You’re in the home stretch! Don’t rush this part. A proper test and careful reassembly ensure your hard work pays off.
Step 5: Connect and Test the Speaker
Before you put the door panel back on, it’s critical to test your work.
- Temporarily Reconnect: Plug in the window/lock switch connectors to the door panel.
- Reconnect the Battery: Go back to the battery and re-attach the negative terminal.
- Turn On the Car/Radio: Turn on your car’s accessory power and your stereo.
- Test the Sound: Use your stereo’s balance and fader controls to isolate the sound to only the new speaker you just installed. Play a song you know well.
- Listen For:
Step 6: Reinstall the Door Panel
Once you’ve confirmed everything is working perfectly, it’s time to put it all back together.
- Disconnect Again: Disconnect the electrical switches and the battery’s negative terminal one more time.
- Reconnect Door Mechanisms: Re-attach the door handle cable and any other mechanical linkages.
- Hang the Panel: Hook the top of the door panel back over the window sill. Make sure it’s seated properly.
- Align the Clips: Look at the panel and the door to align the plastic clips with their corresponding holes.
