500w is not overkill for your needs. One of the biggest misperceptions I fight in car audio is your amp RMS rating can't exceed the RMS of the sub. Optimally, you should shoot for an amp with 1.5x-2x the RMS power rating of your subwoofer. In pro-audio, this concept is called "program power." Thrle manufacturers recommend you run an amp with 2x the RMS of the speakers. If you use a 300w amp on a 300w sub and push your amp past 300w, then you will send a clipped signal to your sub, turning your voice coil into a heating element. You'll also need to keep your gains turned way up, which can add static noise to the system. Use a bigger amp and turn the gains down. That way, you can ensure you're always delivering a clean signal to your speakers. Answer from ClownShowTrippin on reddit.com

r/CarAV on Reddit: Good budget 250-300W RMS monoblock amp with high level speaker input for one 10"?
February 3, 2025 -

Does such a thing exist? I either find good brands that are 500W which are overkill for my needs or cheap ass brands that make bold claims on wattage but only push ~150W RMS or less when tested. Is there any "budget friendly" monoblock amp in the 250-300W RMS range?

I haven't been into the car stereo scene in a couple decades and while I'm not looking to rattle the mirrors off like I did in the past, I like good clean and loud music.

That speaks of other issue and could apply to many amplifiers. Most amps these days tolerate a swing from 12 to 16 volts, that should not be an issue unless your electrical system/design is the limiting factor. The stinger is a good design, neighbor has been running two of the monos since they came out, no issues, work well and are meet or exceed spec.
