Best Amps For 330W Paired with 225W

All Comments say it loves lots of Power and Have read to go for 1.5 - 4 Times The Power Limit is this meaning RMS? WATTS? But not ohms? What about The Difference in RMS or WATTS of the 2 Different Requirements of the Speakers How would you adjust the power for them Both and every amp ive read says nothing about adjusting watts for the correct settings needed

Specs Below
KAPPA 93IX

 Power Handling 110W RMS, 330W peak

Sensitivity (@ 2.83V)   96dB

  Frequency Response 35Hz – 30kHz

Voice Coil Diameter 1-1/16in. (35mm)

 Impedance 2.5 ohms
-----------------------------------------------------------------------------------------------------------                                          
Infinity KAPPA 62IX

Power Handling  75W RMS, 225W peak

 Sensitivity (@ 2.83V)  95dB

 Frequency Response 45Hz – 25kHz

Voice Coil Diameter

1-3/16 in. (30mm)

 Impedance 2.7 ohms

"Power limit" would mean the continuous rating.  Adding headroom on top of that provides for peak handling.

The peak capability of the speaker is what it can do without hitting the end-stops.  The continuous capability is what it can sustain without the voice coil overheating.

But not ohms?
Every amp spec will tell you the MINIMUM impedance it can drive, and how much power it can deliver to a variety of impedances.  Any amp which doesn't tell you that isn't worth buying.

The limitations of a power amp are:
  • The voltage of the output stage power rails;
  • The maximum current of the output stage;
  • The thermal dissipation of the output stage.
The voltage limits the amount of power that can be delivered to a load (the speaker) of any particular impedance.  Drive a 4Ω speaker with 45V and you get 500W, drive an 8Ω speaker with 45V and you only get 250W.  However, if the output stage can only handle 6A, then you'll still get 250W into 8Ω, but connect a 4Ω speaker and it will either limit at 150W or blow a fuse (and by "limit" I mean heavy distortion).

Class D amps don't generate much heat in their output stages (comparatively), but any linear amp will get hot, and that also limits what the amp can do.

You don't adjust the power output of an amp except by the use of the volume control.  If you want to make sure you cannot overdrive the speakers, you choose an amp with a lower output capability than the speakers can handle.  If you want to take the speakers to their max, choose an amp with more than sufficient power capability and be careful with the volume knob.
It's your privilege to disagree, but that doesn't make you right and me wrong.

Relevant: these are in-car speaker units. I suppose they are for in-car use, and not to build home speakers?

Back in the day when I was fiddling with car amps, there were lies, amplifier power figures, and statistics. Are they more honest now?
