I had an extra 99' Orion HCCA15D sub still BNIB from back in 99' on my old dakota r/t build (4 - HCCA15D's / 4 -250R's) and I know it's not a very big deal now with all of the good audio we have to choose from, but those 15's were fkn AMAZING !!! They were so ridiculously efficient and would get loud as fvck on very little power by today's standards... They really only needed 600 watts clean rms to really get down, could take a bit more on burps, but 600 was all they needed and they sounded GOOD ! I Had a buddy who bugged me for years to let him buy it and I finally caved in 2 summers ago and sold it to him for $350 still in the box never mounted, never powered... I soo wish I would've kept that sub //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
