Most spl amps are not as efficient as a small sound quality amp. You can calculate an amps efficiency by dividing the power in by the power it puts out. However,  an easy way to tell is just to touch the amp because an amp that is 75% vs an amp that is 90% efficient will be operating at different temperatures. The more efficient amp will stay cooler because all that 25% of power consumed but not output is released as heat.. again I've had some old school amps ppi, hcca, punch, etc that you could fry eggs on but they were good amps that also put out a bunch of power just were also power hungry because they were not very efficient.</p></blockquote><p></p>
