price not worried about, but I do shop and compare prices before I place an order, what is a kx600.4--is that Kicker I'm assuming ? I searched ebay and came up with several brands under 600.4
Its Brand NEW!!! This amp is VERY under rated. I would say it puts out almost double what is advertised. I have seen this amp push 2 competition 12's extremely Hard. My brother has one of these in his 93 Z28. The 2 front Channels are powering 2 25mm 300 Watt Bullet Titanuim Tweeters. The other 2 channels are pushing 2 American Bass Cast 12's. I was Shocked to sh1t when I heard how loud this thing was. Heres some specs right off the manual, but trust me its waay more powerful than this.
