Last night on my way home from a gig my yorkville AP-6040 fell out of the back of the van (damm boot wasn't shut properly) after taking the top casing off and bending it back into shape a little to my great delight the amps still works perfectly - and you can hardly tell it took a drop! WOW!!! these things are built tough and they can drive 4 18: subs like you wouldn't believe!!!! go the AP-6040 they just don't make em like this anymore!

Compare to the other power amps, this one is cheap.

Draws a lot of current.

I have 2 of them, and they have not given me a problem. A lot of power and good price with a clear sound
