Can a good 375 RMS subwoofer safely handle a 500 RMS amp?

Could I match a Boston Acoustics 12 inch dual-coil 4 ohm to an AQ750 at 2 ohms producing 500 watts if I didn't have the gain up very high?

As long as the signal to and from the amp is nice and CLEAN yes, That woofer should be able to handle that amount of power in a properly designed enclosure.

But doesn't turning the gains down result in less wattage, even if it DID supply too much power can't that be adjusted with the gains setting?

I never said anything about turning the gains down. I said as long as the signal to and from the amp are clean it will be fine. Which means zero clipping and minimum distortion.

But to answer your question...yes turning the gains down results in less output, and yes if you did supply too much power you can turn it down by adjusting the gain.

Dont confuse the gain knob as a volume knob.

What do you mean? When did I do that?

You didnt. Many people get in to that mentality when asking the same question you have posed.

Oh okay. How am I supposed to think of the gain knob then? Does it just regulate the amount of wattage sent to the speakers?

its a line signal device to match the voltage from the hu to the amp

Oh I see... so how are gains supposed to be accurately set then?

in other words, if your headunit throws out 2 volts from the preouts, the gain will be set higher to make the amp produce those 500 watts. if you're starting with a 8 volt preout, the gain will be much lower to get the amp to supply those same 500 watts. if you were to have the gain set at the higher 2 volt setting and swapped for the 8 volt source, you would get considerable distortion and clipping until you matched the amp setting to the 8 volt in.

That makes good sense. Thanks for the insight!

It took me a while to realize that the subs I was looking at weren't good for SQ, which is my main priority. I'm sure they're great subs, but nobody was noting that they weren't good for SQ until I was about ready to buy lol. I had to rethink my game plan

I say you save up your money for a ****** sq system and go focal or eclipse or somethin of that nature haha. If I could I would go back in time and get what I want to get now haha
