Single DIN and Double DIN Stereo Installation
The Metra 99-8151 offers flexible installation options for Lexus IS300 owners.
Single DIN Installation with Pocket
For drivers who prefer a traditional radio design, the kit accommodates a compatible full-recessed Single DIN receiver with a storage pocket.
This configuration is ideal for Bluetooth stereos, digital media receivers, and compact aftermarket head units.
The pocket provides additional storage space below the radio while helping maintain a finished dashboard appearance.
Double DIN Stereo Installation
For owners upgrading to a larger multimedia receiver, the kit supports compatible Double DIN installations.
This makes it suitable for many aftermarket touchscreen stereos offering features such as Apple CarPlay, Android Auto, Bluetooth calling, and navigation.
Actual compatibility depends on the receiver’s chassis and faceplate dimensions.
Two Stacked ISO Units
The kit’s mounting design also supports two stacked ISO units, providing additional installation flexibility for compatible equipment.
Factory-Matched Matte Black Finish
One of the most noticeable problems with an aftermarket stereo installation is a mounting kit that doesn’t match the surrounding dashboard.
The Metra 99-8151 features a painted matte black finish designed to complement the original Lexus IS300 interior.
Its vehicle-specific design helps minimize exposed gaps and provides a cleaner transition between the aftermarket radio and the center console.
For enthusiasts restoring an early-2000s Lexus, this is an important detail. A well-installed stereo should look like it belongs in the dashboard rather than being an obvious aftermarket addition.
Quick-Release Snap-In ISO Mounting System
Metra’s snap-in ISO mounting design is intended to simplify the installation of compatible aftermarket receivers.
The quick-release arrangement provides a practical alternative to improvised mounting brackets and poorly fitting universal trim pieces.
Key installation benefits include secure receiver positioning, convenient mounting configuration, and a cleaner final appearance.
Proper installation still requires following the manufacturer’s instructions and using the appropriate mounting hardware.
Modernize Your Lexus IS300 Audio System
The first-generation Lexus IS300 remains a popular platform for audio upgrades, especially for owners who want to add modern functionality without replacing the vehicle’s original dashboard design.
A compatible aftermarket receiver can introduce:
-
Apple CarPlay and Android Auto
-
Bluetooth hands-free calling
-
USB music playback
-
Touchscreen navigation
-
Backup camera support
-
Expanded amplifier and subwoofer connectivity
The Metra 99-8151 provides the physical mounting solution. These electronic features depend on the separately purchased stereo.
Lexus IS300 Factory Amplifier and Wiring Considerations
When replacing the factory stereo in a 2001–2005 Lexus IS300, remember that the dashboard kit is only one part of the installation.
Depending on your vehicle’s original audio configuration, you may also need a wiring harness, antenna adapter, or factory amplifier bypass or integration solution.
Some Lexus IS300 configurations use a separate factory amplifier behind the glove box. If you’re replacing or bypassing that amplifier, verify the speaker wiring and electrical compatibility before connecting a new receiver.
