Whats the worst that can happen, they catch on fire?

>>25650204 I think it damages them and the amp if I understand correctly though it should be safe to run more power than they need if they have impedance within the amps range of 2-8 ohms..

also, why doesn't windows 11 have 2.1 channel audio mode?? I want to run stereo setup with a subwoofer in the subwoofer plug but windows only sends signal to the subwoofer plug in 5.1 or 7.1 mode so you have to use 2.1 channel amp which are more expensive and run it out of the front stereo channel plug

>>25650266 >in 5.1 or 7.1 mode Those are proprietary modos supported only by your soundchip manufacturer, not wangblows itself. >>25650188 165W at 4ohm advertised means theoretically 110W for 6ohm at 100% volume knob. For real usable volume cut that amount in half. Most importantly, check what impedance your subwoofer is, and how much power output this shitbox can offer for it. Don't buy Fosi, their stuff is bad for the price - noisy, distorts, sounds poor in general. See if you can grab any speaker amp from SMSL or Topping audio, those two are high tier/audiopedofil approved, yet with very reasonable pricing.

>>25651034 >>25650188 Also no, too much power isn't an issue - you will be able to tell by the sound volume, and lower the knob accordingly (thus lowering the delivered wattage)

>>25650188 >I have speakers rated for 6 ohms impedance but the wattage is unknown, I think they're 80 watts max each would a 165w x2 mini amp be enough to power them? Wattage is irrelevant in audio. Well theoretically not but practically the numbers used are fantasy. You can (theoretically) use any audio amp with any speaker. But there are bad weak amps, regardless of the watt number they claim and print on it, that will struggle to power certain badly designed speakers. The important factor is in fact the impedance of the speaker, not the nominal one but the actual minimum resistance, Ohm on the impedance curve. Nominal 6 Ohm speaker should be no problem for any amp, but the important factor is will the impedance go lower than 4 Ohms on any point of the frequency/Ohm impedance curve? The lower the effective resistance of a speaker at a given frequency, the more difficult amps will have to drive a speaker. That is a logical result of Ohms law were lower resistance results in higher current, Ampere, but amplifier are not able to deliver infinity Amperes. When the demand of the speaker for Ampere rises the quality of the amplifier signal falls until you have pure distortion, that theoretically can destroy a speaker. In the end you can control how much Ampere will flow from your amplifier with the volume knob who controls the voltage that will appear at the output. Less Volt, less Ampere at any given resistance/impedance Ohm.

>>25651034 it does 350 watts for the subwoofer and the sub is 4 ohms I'll look at those brands too, thank you bernd! >>25651043 Ah okay that makes sense >>25651730 I think I read somewhere that the minimum they'll go is 3 ohms but I'm not sure and that polish bernd did say that fosi is noisy.. I'll keep looking thank you audio bernds!

Basically any amp works with any impedance (as long as it's in the usual range and that is not a hard limit). The lower the impedance, the lower the output (in watts) of the amplifier. If you never use maximum volume (it is very loud, too loud), none of that stuff will matter. Btw good choice to buy a class D amp. Based on experience, I recommend ones with ST chips over ones with TI chips.

>idk how impedance is calculated isn't it just Ohm's law?

>>25655265 pretty much all of them I can find on amazon use TI chips..

>>25655277 what am I, a mathematician?

>>25655400 school grade 8 physics I mean it's an easy one: current (amperes) = voltage (volts) / resistance (ohms) how you get watts from here idk

>>25655419 Watts = volts * amps Therefore watts = volts * volts / ohms
