Question about Legacy Audio American Legacy II LA290 Car Audio Amplifier
Check the unit for any Fuses, Fusable Links etc, if they are OK proceede on to testing, I often troubleshoot these issues via a stereo head set, modify the leads so you can "Touch" them onto the Speakers Output Terminals, connect the "Shields" together, thats "Earth" and the other Two, are Left & Right... with a Sinal feed in & the Amp's volume turned to about 25% volume, connect up the Earth wires to the Chassis with a clip, under a srew etc, just make good contact... then touch the Left & right wires onto the output, ya should hear sound... if not most probably the Output device(s) may have gone faulty.
