  • Excellent sub for sxs
Style: Singe 12" 1 Ohm
As a veteran of mobile sound systems I believe that I have found the best equipment for the price. The cost is deceptively low for performance. I would put Rockville's product against any name brand out in the market and win every time. Very satisfied. Still haven't found max volume setting. I run out of ears before I run out of volume ... show more

  • Getting the right power configuration
Style: Singe 12" 1 Ohm
I like it so far but I have yet to figure out the right setup for the amp pushing it. The gain on my 1400w 500RMS amp is barely a 1/4 up and it sounds as if it’s going to blow. So I have to do some more adjusting, but overall it plays great. I just can’t crank it all the way up yet.
