Hifonics ampm is 90% efficient the jbl amps are not efficient at all mybe 70% so to run 2 jbl's u would need a 200 amp alternator so thats why the hifonics amps are slightly better as for 2 amps ive herd that the orion isnt that efficient either...... but u could always buy a hifonics collosis... nobody ever mentions these same power as the orion more efficient
