On realm excursion theres a vidoe of a guy with one 12 inch type r powered by 2 memphis 1000d amps witch are 1100 watts rms each a type r can handle that much power can it?
That's Mark a.k.a Spkrman from the caraudiobox.com...and trust me..he's clipping the hell out of those amps. Gains have nothing to do with actual output. Technically, you can reach full output with the gain all the way down on ANY amplifier. The Type R 15 can handle PLENTY of power..much more than what its rated for. Currently he's running 2 Type R 12's in a wall on an Orion 2500D...and they take that power all day.
Well, obviosly you can reach full power output with the gains all the way down, I know that. But if the gains are all the way down you have to turn up the volume ALOT more, and it also depends on what the actual line out voltage on the HU is. The gain does control how much power the amp puts out.
it controls how much input signal for "x" amount of output signal. so the more sensitive the gain, the less of an input signal you need to get the same output.
the amp will make it power regardless of the gain knob.
besides that, if the coils are rated at 500wRMS, they will melt after about 800wRMS or so, they just aren't made for any more heat, regardless of excursion.
now i know most every sub is underrated as far as power handling, to protect the manufacturer, but i doubt that they could take 4 times the power w/o damage.
