Lexus GS350 Speaker FAQ

What speakers should I replace first in my Lexus GS350 for the biggest sound improvement?

Replace the front door speakers first. These handle most of your music's midrange and vocal frequencies. The 6 x 9 inch front speakers in newer GS350 models typically run around 25-50 watts RMS at 4 ohms. Component speakers will give you better sound separation than coaxials - the tweeter mounts separately for clearer highs. If your Lexus GS350 has the factory subwoofer in the rear deck, upgrading fronts becomes even more critical since they'll handle everything above 80-120 Hz.

Can I install component speakers in all Lexus GS350 door locations?

Yes, both front and rear door panels accept component speakers. The front 6 x 9 inch locations might need mounting brackets though - not all component sets include oval adapters. Rear doors take 6.75 inch or 6.5 inch components depending on your specific GS350. Component systems separate the tweeter from the woofer, usually improving frequency response by 3-6 dB in the upper ranges. You'll need to find tweeter mounting spots or use the factory locations if they exist.

What's the difference between coaxial and full-range speakers for the Lexus GS350?

Coaxial speakers have a tweeter mounted on top of the woofer cone. Full-range speakers attempt to reproduce all frequencies with a single driver - no separate tweeter. The 4 inch center dash speaker in newer GS350 models can be either type. Coaxials generally perform better above 2-3 kHz because of the dedicated tweeter. Full-range speakers might struggle with high frequencies but can sound more cohesive since there's no crossover point. Power handling is usually similar - expect 15-30 watts RMS for the center dash position.

Should I upgrade the factory 10 inch subwoofer in my Lexus GS350 rear deck?

The factory 10 inch sub might be adequate if you're not seeking deep bass below 40 Hz. Most factory units produce around 100-150 watts RMS and roll off sharply around 35-45 Hz. Aftermarket 10 inch subs can handle 200-400 watts RMS and extend down to 25-30 Hz. The rear deck location isn't ideal acoustically - trunk mounting often provides better bass response. Consider whether the factory amplifier can drive a replacement sub properly. Some GS350 models have integrated amplifier systems that complicate upgrades.

What impedance should I choose for Lexus GS350 replacement speakers?

Stick with 4 ohm speakers. The factory Lexus GS350 amplifier is designed for 4 ohm loads and will produce maximum power at this impedance. Using 8 ohm speakers will reduce power output by roughly half. 2 ohm speakers might overload the amplifier and trigger protection circuits. Most quality aftermarket speakers come in 4 ohm versions anyway. If you're adding an aftermarket amplifier later, 4 ohms still provides the best flexibility for most amp designs.
