Oldsmobile LSS Speaker FAQ

Which speakers should I replace first in my Oldsmobile LSS for better sound quality?

Replace the front door panel speakers first. The 4 x 6 inch front speakers handle most vocals and midrange frequencies you actually hear while driving. Rear deck speakers mostly add bass fill and ambient sound. Front replacement typically gives you 70-80% of the total sound improvement for half the work. The Oldsmobile LSS front location also tends to have better acoustic positioning than the rear deck.

What's the difference between coaxial and component speakers for the Oldsmobile LSS front doors?

Component speakers separate the tweeter from the woofer - tweeter mounts separately, usually in the door panel or dash. This might give better soundstage since tweeters can be positioned closer to ear level. Coaxial speakers combine everything in one unit, which makes installation simpler in the LSS front door panels. Components typically cost more and require more wiring work. The 4 x 6 inch size somewhat limits the benefits of going component since the woofer area is already constrained.

Can I install 6.5 inch speakers in place of the 4 x 6 speakers in my Oldsmobile LSS?

Not directly. The 4 x 6 inch mounting holes won't accommodate round 6.5 inch speakers without modification. You'd need adapter brackets or custom mounting. The LSS door panel depth might also be insufficient for larger speakers. Stick with quality 4 x 6 inch replacements - you'll get significant improvement without fabrication work. Look for speakers with 20-60 watts RMS handling and 4-ohm impedance to match the factory setup.

What should I look for in replacement 6 x 9 speakers for the Oldsmobile LSS rear deck?

Focus on speakers rated 30-80 watts RMS with 4-ohm impedance. Triaxial designs include a small midrange driver plus tweeter and woofer, which can provide fuller sound than basic coaxials. The rear deck location in the LSS actually works well for 6 x 9 speakers since they have room to move air. Look for frequency response extending down to 35-40 Hz for decent bass output. Sensitivity around 88-92 dB helps ensure adequate volume from the factory radio.

Will replacing speakers improve bass in my Oldsmobile LSS without adding a subwoofer?

The 6 x 9 inch rear speakers will provide noticeably better bass than factory units. Quality aftermarket 6 x 9 speakers can typically reproduce frequencies down to 35-45 Hz with reasonable output. However, the LSS cabin size and speaker mounting locations limit how much true low-end bass you'll achieve. The front 4 x 6 speakers won't contribute much bass due to their size constraints. Expect improved midbass punch and clarity rather than deep subwoofer-level bass.
