Lexus LS600h Speaker FAQ

What speakers should I replace first in my Lexus LS600h for the biggest sound improvement?

Start with the front door panel 6x9 inch speakers. These handle most of your music's midrange frequencies and vocals. The front doors typically see 50-100 watts RMS, making them your primary sound source. Replace these with quality component speakers rated for 4-ohm impedance. You'll notice immediate improvement in clarity and staging. The dashboard 4 inch speakers come second - they fill in the soundstage but won't transform your system like the front doors will.

Can I install a component system in the Lexus LS600h front doors?

Yes, the front door panels accommodate component speakers. The existing setup might already separate tweeters to the A-pillar location. Mount the woofer in the 6x9 inch door opening, then run new wiring to the A-pillar for the tweeter. Check crossover placement - some fit behind the door panel, others need mounting elsewhere. The 4 inch A-pillar space should handle most aftermarket tweeters, though you might need custom mounting brackets.

What's the difference between the coaxial and component speakers in the LS600h?

Coaxial speakers combine multiple drivers in one unit - tweeter mounted on the woofer. The dashboard and rear door coaxials are simpler installs but compromise sound quality slightly. Component speakers separate the drivers. Your front doors can use either coaxial 6x9s or component systems with separate tweeters. Components typically sound better because each driver optimizes for its frequency range. The crossover networks also tend to be more sophisticated than coaxial designs.

Should I upgrade the rear deck lid subwoofer in my Lexus LS600h?

The 8 inch rear deck subwoofer handles bass frequencies below 80-120Hz. Factory units usually run 20-40 watts RMS, which might feel weak. Upgrading gives you deeper, more controlled bass. Consider the enclosure type though - deck lid mounting limits box volume. A quality 8 inch sub with higher excursion might work better than going larger. Some owners bypass the deck location entirely and install a proper subwoofer system in the trunk area instead.

What power ratings should I look for when replacing LS600h speakers?

Match the factory impedance first - typically 4 ohms. Front door 6x9 speakers should handle 75-150 watts RMS comfortably. The 4 inch dashboard and rear door speakers work fine with 30-60 watts RMS. Don't over-power the smaller drivers. The rear deck subwoofer can take more power - 100-200 watts RMS if you're adding an amplifier. Factory head units usually output 15-25 watts per channel, so high-efficiency speakers matter more than maximum power handling.
