Amp matching?

[olds1959special]

How do I match amp levels? Amps A are dual Kenwood LM-05 amps (100 watts) driving the bass of my 2ci’s. Amps B are dual Fosi ZA3 Class D amps (120 watts) driving the midrange treble. The issue is, even though the Fosi amps have more power, I can’t tell if they are louder or softer (when maxed) than the Kenwoods.

I think the class D amps are indeed more powerful as stated by ratings so I turned those down.

Probably with a 1KHz tone and then measure the amp’s output voltage.
Once you know the ratio, then you could PAD down the power of the one with higher gain, to match the one with less amplifier gain.

But at some point a DSP might be easier, as you can do it all digitally.

I just played pink noise and measured with an RTA to see the effect of the crossover and adjusted based on that. I had my treble/midrange turned up a little too much, which I suspected.
