I was told some of there older shit was cool, what about the mojo 15's!
ive done the same thing! that 1000d is a SOLID amp.Their amps are TOUGH as nails and do NOT overheat. I had a Memphis 1000D running 2 L5 10's...I shit you not I rode from GA to TX (about 800 miles) and I NEVER turned off the system. I beat it at prolly 1/2 - 3/4 volume for a solid 10 hours without having it miss one beat. that was the moment when I fell in love with the Memphis line of amps. They are tough, put out the power, and stay cool.
BTW that was with the amp running at 1-ohm
