Check the opening and mounting depth first
These are 6.5-inch coaxial speakers, so the first question is whether your factory location accepts that size. If you already have 6.5s in the doors or rear deck, the swap is plausible, but the depth behind the opening and the screw pattern still decide whether they seat properly.
We'd consider these for a straightforward upgrade where the factory hole matches. We'd skip them if your vehicle uses a different opening size or a proprietary mounting bracket, because a size mismatch turns a simple speaker swap into fabrication work.

What these speakers can and can't tell you
The S2-S65 is a playback device, so its job is reproducing audio rather than diagnosing anything in your car. A discount on it says nothing about a fault in your existing system or whether your vehicle is safe to drive.
What it does claim is audio performance. The coaxial design puts the tweeter inside the woofer frame, the cone mixes polypropylene, glass fiber and mica, and the HAMR surround is built for cone travel and bass output. Hi-Res Audio certification covers reproduction up to 40kHz.
Diagnostic boundary: this is a speaker, not a fault-finding tool.
Certification claim: Hi-Res Audio, up to 40kHz.

At $120.55, the set sits $24.02 below the typical price over the last 90 days of $144.57, a 17 percent difference. That gives you a reference point, though it is an average rather than a prior sale price.
Buyers have left 174 reviews, which is useful context on the product but not a fitment guarantee for your specific vehicle.
Match the amp and wiring before you install
The power figures are 240W peak and 80W RMS, so check what your head unit or amplifier actually delivers to each channel. Feeding them from a modest factory radio is fine, but the RMS rating is the number to compare against your amplification.
If the speakers will be visible, the KTE-S65G grille is sold separately. Confirm the mounting depth, the screw holes and whether you need that grille before ordering.
Who should buy this set
This set suits someone replacing tired 6.5-inch factory speakers in a vehicle that already takes that size, especially if clean highs and a certified frequency range matter to you. The current $120.55 is below the 90-day typical price, which makes the timing reasonable if the size is right.
If your doors use a different opening, a shallow depth or an odd impedance requirement, measure and confirm before you order, because those checks decide whether this set fits at all.
