So a friend of mine was looking into some new components for his '01 GMC Sierra Ext cab. He was going to power them off a stock head unit, but after I explained that they'd be severely underpowered, we started looking into new head units, and probably amps for the components. Then, I found the Panasonic MXE CQ-C9800U. 4x60w RMS?!?! I know that this Tripath amp stuff is supposed to be really efficient, but come on, can they really mush that big of an amp into that small of a package? Has anyone used one yet, and how does it sound? For the cost of a good amp and a head unit, I don't think the cost is too shabby, but I want to make sure the thing is good before recomending it!
