Crutchfield Customer Review (What's this?)
After a lot of research, I chose the MTX Thunder564 becuase it represented the best value I could find on a car amplifier. It even came with a certificate filled out and signed by a 'human' stating measured power output and THD. <BR><BR>Having worked as a car audio seller and installer for seven years, I appreciated the no-nonsense clearly lableled controls, inputs and outputs. During installation, I didn't even need the owner's manual. <BR><BR>I am driving a pair of Polk db6500 and a pair of Polk db650's in parallel off of 2 stereo channels, and a Polk GNX-10 sub off of the other two bridged mono. As this amp can suck a lot of juice at full output with arrangement, I also bought (and recommend) a 4G power distribution kit for this amp.<BR><BR>It's not all good though. The high frequency detail is not the best I've ever heard, a little edgy at low-to-normal levels and breaking up a bit at higher levels (I know what clipping sounds like, and an not clipping the amp). The low freq performance of this amp is very good-to-excellent, and the mids are generally smooth, but lack articulation in the upper registers. Some of these qualities could be aggravated my Polks or speaker location in my Honda Pilot.<BR><BR>With that said, considering that most amps this price and quality have 30 watts x 4, the excellent balance between power output, price and sound quality earn this amp 5 stars in my book.
