Define "high output"
Hypothetical.....
90dB @ 30w
93dB @ 60w
96dB @ 120w
99dB @ 240w
102dB @ 480w
Factor in baffle stepped response, off axis listening effects, road and engine noise, more.
Then consider amplifier efficiency.
Then realize that an amp rated a 30w doesn't put out 30w all the time. RMS power is not average power.
