Sometimes we say that a product works with your vehicle. This means that it doesn't necessarily fit in a factory location, but that it's designed to be compatible with your vehicle's electronics or interior design. Compatible products include products like adapters (for Bluetooth or smartphone control, for example) that plug into your vehicle's stereo wiring harness and device holders mounts in a specific spot on the dash.

We also carry a wide range of products that are designed to work exclusively with specific vehicles. See below to learn more.

If you're in the market for new speakers, here's what you'll find when you shop with us:

• Filtered lists of speakers that satisfy the depth, diameter, and height requirements of your vehicles factory speaker openings
• A breakdown of speakers available for specific locations in your car
  • These can include locations that don't have factory speakers, but can be adapted with certain mounting adapters, such as pods that let you mount speakers in your kick panels
  • We won't list a given location if no speaker option is available for it. When you use Outfit My Car^sm, you'll see the kinds of essential factory stereo and speaker information our research team gathers.
• Alerts to add the required brackets and harnesses to your cart — these are free when you buy any set of speakers from us Speaker orders also qualify you to receive the vehicle-specific installation instructions we offer.

Many manufacturers have designed products that work directly with specific vehicles. These include:

• “Direct” replacements for certain products, such as speakers.
• Products that take advantage of unused space in the car, such as subwoofer enclosures custom-designed to fit in places that don't sacrifice trunk or cargo spaces.
• Products that plug directly into your car's wiring and work with your factory stereo, such as Bluetooth hands-free adapters or sound processors.

Many car A/V products we describe as “universal,” in that there aren't dedicated factory locations for them. With many of these products, you'll have to check your vehicle for available space, and carefully plan your installation in advance. The most common include:

• Amplifiers Amps require three things: a mounting location, power wiring directly to your car's battery, and wiring for musical signal. You'll need to check the dimensions of the amps you're interested in, which we provide, then measure the available space you have in your vehicle. Mounting locations can include underneath seats or in the trunk or cargo area. We'll show you the size of wires you'll need when you make your purchase, and we can offer tips online and by phone for wiring strategies.
• Subwoofers Just about all subwoofers need to be mounted in an enclosure, which then fits in an available spot in your car. As with an amplifier, you'll need to measure space in your vehicle to see if the subwoofer you're interested in will fit, while leaving you enough cargo space for your needs. If you choose a powered subwoofer, we'll make sure you get the right power wiring; if you choose a sub and box, we'll recommend the right size of speaker wire, which you'll connect to the external amp that'll send power to the sub.
• Portable products such as GPS navigators, radar detectors, and dash cams. You'll just want to make sure that you have a dash or windshield large enough to accommodate the mounting systems of these sorts of products without interfering with your sight or operation of the vehicle.
