Collection: Audio

Car audio improvements range from swapping the speakers to fitting a new head unit, amplifier and subwoofer. Factory systems are usually the weakest link, so speakers often give the biggest improvement for the least money. Fitment is model-specific, so speaker sizes and head unit dimensions have to match your vehicle. Think about what bothers you about the current sound, then start with the component that actually causes it.

What car audio components are there?

A system is built from a few parts:

• Speakers: the biggest single improvement over factory units, in sizes specific to your vehicle's door and dash openings.
• Head unit / car stereo: the dash stereo, adding Bluetooth, phone mirroring and better output.
• Car amplifier: drives speakers properly at volume, where a head unit's built-in power runs out.
• Car subwoofer: handles the low bass that door speakers physically can't produce.

What size speakers fit your car?

Car speakers come in standard sizes matched to the openings in your doors, dash and rear shelf, and the size varies by make, model and even trim level. Common sizes include 5.25 inch, 6.5 inch and 6x9 inch, but you need to confirm what your vehicle takes rather than assume. Mounting depth matters as well as diameter, since a speaker that's too deep will foul the window mechanism inside the door. Check both the size and depth for your exact vehicle. Tip: upgrading front speakers first gives the most noticeable improvement, since that's where most sound is directed.

Do you need an amplifier?

A head unit has a small built-in amplifier, which is enough for moderate volume with efficient speakers but runs out of headroom quickly. The symptom is distortion as you turn it up — the sound gets harsh and muddy rather than just louder, which is the amplifier clipping. A separate amplifier provides clean power so speakers perform properly at volume and stay controlled. It's essential for a subwoofer, which needs far more power than a head unit can supply. If your system sounds fine at your normal listening level, you may not need one.

Common questions

What size speakers fit my car?
It varies by make, model and trim — common sizes are 5.25, 6.5 and 6x9 inch. Check both diameter and mounting depth for your exact vehicle, since a deep speaker can foul the window mechanism.

What gives the biggest sound improvement?
Replacing the factory speakers, particularly the front ones, since factory units are usually the weakest part of the system and most sound is directed at the front.

Do I need an amplifier?
If sound distorts and gets harsh as you turn it up, the head unit's built-in amplifier is clipping and a separate amp will help. A subwoofer always needs one.

What does a subwoofer add?
Deep bass that door speakers physically can't produce because of their size. It gives music a foundation and weight rather than just making things louder.
